Someone wants to sell a used electronic Legacy crossover. I could use one and this is real cheap. But how can I test it to make sure it works and I don't get screwed? I don't have any systems put together yet. Just gathering the pieces
I would recommend a mtx 3 way crossover they work great and helps the ground noisy problem. If still want to check that crossover , the only way to do it is to connect it to a system a listen to it.
Specifically an mtx crossover. What does it do??? does it make it sound better?
A crossover tells your speaker what you want it to play. You can have it set to play only low frequency parts, middle or high, or in between the few if it is a turn knob. If you are using one on an amp for subs, set it low so only low levels of sound bass through it for your bass to play.
crossover: Simmetry EXP2; Tweeters: Kicker R13
They're probably capacitors, not condensers. If you're using a separate active crossover then no, you shouldn't need to use the filter caps.
Hello, This is what I have going, 2 5 1/4 two was speakers (front). 2 5 1/4 speakers (rear). They are very low wattage, rating right under the Head unit output rms. I am not using any amps, just the head unit to power. Everything worked but then I tried to add an electronic corssover (boss) to try and tune the sound further. When I hook it up (and I double check all connections) There is no sound from the speakers connected to the crossover. There is power to the crossover, it is lit up and speakers are all connected good. What could the problem be ?? I only connected the rear speakers to test so the front are connected directly yet, they produce sound but the rear going through the crossover, has nothing, just dead and the crossover is powered up. What could it be ?
you have to have an amplified signal running through your crossover in order to get sound from your speakers. to use your external crossover you have to have an amplifier hooked up as well. only way around this is to buy a head unit with built in high and low pass crossover like an alpine head unit. check out my profile for a list of my car audio goodies
Amp - Boss CH-1500 Class D Mono - 540rms @ 4ohm / 800 rms @ 2 ohm - 1500 peak
Electronic Crossover - MTX Rt-X02A crossover. Two high pass & one low pass crossover points, Selectable bass enhancement circuit, 12dB/octane slope (http://i2.ebayimg.com/02/i/000/e2/98/a598_1.JPG)
Sub - (Single) Kicker S12L5 - DVC - 1200 peak / 600 rms
Enclosure - Slot Port Vented and Tuned to 35hz
...........Also note that I will be setting my amplifier input sensitvity via voltometer to match that of my head unit.
If building a complex system using
eg subs mid bass and then components for mid bass and high freq's
yes add a xover between amp and head unit this way one can easily dial the freq's much more accurately to match the systems design....in other word there is much more flexibility's to grow the system...to mutli speakers and amps' and keeping the tuning of them much more accurate and efficient...by dividing the freq's prior to the signal being amplified.
If just running Sub(s) and full range....it is not necessary to add an electronic xover if the amp already has one...and the amp listed does and would do the job for your subs
The MTX xover listed is a 12db/octave which is common xover slope in many of the amp's today
note since you are using a ported enclosure and want a excellent crossover and want to add one....look for one with at least an 18db/octave subsonic filter to accuately tune your subs(many amps also have subsonic filters)
I currently have a Kenwood amp running my 2 10" subs. i want to add an amp to power my alpine 6x9 speakers. do i need to buy an electronic crossover? distribution block? relay? and can anyone send me a link that has a diagram on how to setup 2 amps. thanks a lot!
a distribution block is the first thing a 4 gauge wire from the battery to the distributer then from the 2 separators split to 8 gauges to the cap.
the capacitor goes to the amps with 8 gauge wires. and the amp goes to the speakers with 14 gauge wires
I need to know if I need an electoronic crossover and a distribution block?
How and what do you connect a capacitor?
Where should the fuses go?
*What else do I need if a get a deck, one sub+one amp, 4 speakers+another seperate amp, a capacitor, a distribution block, an electronic crossover, and fuse holders, fuses, and wires?
Have a pro do it. There is WAY too much to explain that can be put on here.
Go here for starters so you know some terminology:

Here's a diagram of my system:

How to install a cap:
It has to be charged just before you supply power to it.
It's best to install it as close to the amp as possible. You may need to get addition power and ground wire the same size you have now. Otherwise, cut the ground and power wire leaving enough room to mount it. The overall length of the ground wire should as short as possible (18" or less if possible, not critical).
Remove the fuse at the battery. If you don't have one, you need one that is rated the same as the total fuses that are on the amp. It must be no more than 18" from the battery.
Connect the ground from the chassis to the cap then to the amp.
Connect the the power wire (from fuse by the battery) to the cap then to the amp.
To charge the cap, get a 12v light bulb with leads. Temporarily connect the power wire from the battery to one side of the bulb (at the fuse) and connect the other side of the bulb to the wire going to the cap. The bulb will light and over a period of time (10-20 seconds) it will get dimmer. When the bulb goes out, the cap is charged. Basically, your going to put the light bulb where the fuse was.
Now you can re-install the fuse.

IMPORTANT: Make/print a sign/note that states:
"WARNING: This vehicle employs a large electrolytic capacitor for the electrical/audio system. The capacitor holds a charge EVEN when disconnected. When changing the battery, remove this fuse. Take caution and charge the capacitor prior to replacing this fuse. SEVERE INJURY OR DAMAGE MAY RESULT IN FAILURE TO COMPLY!"
Have a big red arrow pointing to the fuse and one of those yellow triangles with the exclamation point in the center. Laminate this sign and place it near the fuse by the battery.
Something like this:

So we decided to get a Weber grill but have questions about some of the differences between different models of Weber grills. I checked Weber's website and they have no information about the following::
1. One type of grill has a "crossover" ignition, while the other type has an "electronic crossover" ignition. What's a "crossover ignition" and what's the difference between the two different types of ignitions?
2. One grill has porcelain enameled cooking grates, while the other has porcelain coated cast iron. When the grill has porcelain enameled cooking grates, what material does the porcelain enamel cover?
3. Is a sideburner worth the extra cost?
Thanks for the help.
crossover ignition just means that one burner can be lit by the flame of the other. electronic crossover has an electronic igniter for each burner.
porcelain enamel, unlessotherwise stated, is probably over steel.
and, i rarely use my side burner. unless there is no wind, they are very fussy, and the unsheltered flame tends to blow out.
i'm trying to figure out how to make my own electronic passive crossovers for my speakers. i know the equations for inductive and capacitive reactance, but the idea of resonance is escaping me. i am trying to calculate a high pass filter for an 8 ohm load and a low pass filter for a 4 ohm load, the crossover being 2KHz. i'd like to know the general equations used, so i can apply them to future projects.
look up an elctronics book at the library

As a sign of the times, Lexus is discounting the numeric portion of its mid-size sport ute's name by ten counts, though not at the expense of capability, price, or prestige. To the contrary, the new second-generation GX 460 is slightly quicker and all the more laden with luxury touches. The surname change is attributable to the new V-8's displacement change from 4.7 to 4.6 liters.
While the GX 460 is not part of the headlong market shift to crossovers, it does achieve a couple more miles per gallon in EPA highway and combined ratings. This is the last body-on-frame, live-rear-axle classic SUV in the luxury class, largely because this Lexus shares core components with the lowly Toyota 4Runner, a longstanding member of the ground-pounding (off-road) fraternity.
According to Lexus, the 2010 GX is a clean-sheet design embodying a new body, frame, and powertrain. Unfortunately, customers are leaving this segment in droves. Lexus has its fingers crossed that 56,000 youthful, well-heeled customers will remain behind and that it will be able to snare a quarter of them to sell 14,000 GXs this year. That seems like a stretch to us.
Six years ago, when Automobile blessed the GX 470 with its All-Star award, fuel was cheap, life was great, and a luxurious three-row family hauler was a gratifying ego stroke. Then competitors flooded in, the world economy imploded, and fickle consumers took refuge in smaller, lighter, more fuel-efficient conveyances.
L Finesse Design
While the concept of L finesse is largely lost on western eyes, Lexus offers a machined and polished steel bar as the new GX's thematic model. The GX's exterior is slightly more chunky appearing, especially in the more prominent rear haunches. Basic proportions are longer, lower, and wider though the 109.8-inch wheelbase is unchanged and dimensional alterations are modest. One curiosity is that exterior dimensions now align perfectly with Toyota's mainstream crossover, the Highlander.
Consistent with the solid steel bar theme, curb weight is up a hefty 400 pounds over the previous model thanks to the addition of more sound deadening and added electronic entertainment gear.
Exterior highlights include meatier grille bars, a more elegant front to side surface blend, and a more dazzling headlamp cluster. Eighteen-inch wheels are standard on both base and premium editions. The upscale model has extra side chrome and ding protectors attached to the lower door areas. All rear lamps are LED designs, the wiper is tucked out of sight beneath the roof spoiler, and the rear glass can now be opened without unlatching the surrounding hatch to deposit small items in the cargo hold. ...next page >>
The Kluger’s exterior styling, like its name, is unremarkable. You won’t find any excesses of style or seductive lines here - just a plain, functional, two-box body.
At 1910mm wide and 1760mm tall, the Kluger is larger than the Ford Territory in every dimension except length. It’s a big machine, and its bulging features amplify its size.
The Kluger’s flanks are big slabs of metal. There is some shaping of the fenders to break up the large expanses of steel (and emphasise the wheelarches), but there is little in the way of subtlety.
The 19-inch alloys fitted to the Grande improve the exterior style and the chrome doorhandles (also exclusive to the Grande) are a nice touch.
The Grande also gets foglights, roof rails, a rear spoiler and a large moonroof as well, but aside from some minor differences the bumpers, lamp clusters and brightwork are largely the same as the base model Kluger KX-R.
InteriorIf only one word could be used to describe the Kluger’s cabin, it’d be “huge”. There’s acres of sprawling space in the back, and enough room for seven people to travel in comfort.
All models bar the base KX-R are available only as seven-seaters, with the seven-pew layout an option for the KX-R. The third-row seats fold into a flat boot floor when not in use and are comfortable enough for two smallish adults, although most will find the legroom and headroom a little snug.
There’s no such complaint in the second row. The seats are large, comfortable and fitted with folding armrests. The centre seat can even be folded down, stowed away and replaced by a plastic tray, turning the outboard seats into two individual captain’s chairs.
The second row seats can slide fore and aft and feature adjustable backrest rake. When cargo volume needs to be maximised, the backrests fold flat on top of the squab and line up with the flat boot floor created by the folded third row seats.
Folding the seats is an effortless process, with most actions achievable using just one hand. folding them, however, did require a bit of finessing.
Controls for the Grande’s rear cabin ventilation system are mounted on the rear of the centre console, and are within easy reach of the second row occupants. The Grande also comes fitted with a roof-mounted DVD player for the rear cabin – a boon for parents with children to entertain on long trips.
As nice as the accommodation in the rear is, the front seats are even better. Up front, both seats adjust electrically and feature soft supportive cushioning. The Grande gets heated front seats, and all seats are trimmed in leather.
The driving position is a commanding one, and visibility over surrounding traffic as good as you’d expect from a car this tall. The steering wheel adjusts for reach and rake, and finding a comfortable driving position is easy.
Rearward vision is good (aided by a reversing camera in the Grande), and Toyota has thoughtfully included a wide-angle mirror above the rear-view mirror (so that Mum, or Dad, can keep an eye on the action in the back).
The dash is thoughtfully laid out, and dominated by the four large rotary knobs for the temperature controls and audio system.
All buttons are large and easy to interpret, but the sheer breadth of the cabin makes some of those on the passenger side hard to reach from the driver’s seat. Steering wheel-mounted controls for the audio, climate control and phone systems help alleviate the problem though.
The electro-luminescent instruments are bright and clear in virtually all lighting conditions, and include a tachometer, speedo, engine temperature gauge, fuel gauge and gear position indicator.
A multi-function trip computer screen is mounted above the large central touchscreen display, and also displays climate control settings. A handy feature on the Grande is the ability to set the temperature for the rear cabin from the front seats.
The centre console is wide, and houses four cupholders, two 12V power outlets, a commodious storage box and the gear selector. Each door is fitted with a well-sized storage bin, and there are four more cupholders spread over the rear cabin.
Equipment and features
Being the flagship of the range, the Kluger Grande is packed full of gizmos.
There is the aforementioned three-zone climate control, Bluetooth phone integration, heated seats, moonroof, rear DVD player and reversing camera, along with other standard Grande features like keyless entry, a push-button starter, cruise control, satellite navigation and an auto-dimming rear-view mirror.
There’s also a four-CD changer for the integrated MP3-compatible stereo, along with auto-on headlamps.
The separate glass hatch in the tailgate makes it easier to load small items into the boot, while the Grande’s power-operated tailgate eliminates the need to hoist it open or swing it closed manually.
Active safety features include ABS, electronic brakeforce distribution, brake assist, traction control and stability control, all of which are also standard on the rest of the Kluger range.
St. Paul, Minn. — Sensors in roads and in vehicles provide new ways to minimize crashes, and the deaths and injuries that come with them.
Last year in Minnesota vehicle crashes caused 455 deaths, but two innovations are designed to help drivers avoid them.
Advisory speed limits
For years, Minnesota Department of Transportation cameras have been able to beam pictures of traffic backups to the Regional Transportation Management Center in Roseville.
Now, sensors in the freeway roadbed will detect slowing traffic, according to Brian Kary, MnDOT freeway operations manager.
The sensors control electronic signs over each lane. Within a split second - and seconds count for a lot in crash avoidance - the sensors will tell the signs to post advisory speed limits for drivers.
"We can get people to slow down sooner so they don't suddenly become caught off guard with some stopped traffic downstream," Kary says. "It gets them to take their foot off the gas."
And with luck avoid a rear end collision - statistically the most prevalent kind of crash.
MnDOT's advisory speed limit system on 35W is the first of its kind in the country. The speed limits are advisory; there's no enforcement.
In western Europe where similar advisory speed limits are actually compulsory and drivers are ticketed for infractions.
Emergency braking systems
The other crash avoidance idea is just now in auto showrooms. The Volvo emergency braking system is the first among major automakers.
On a recent test drive, Borton Volvo salesman Tristan Grobel steered an XC60, a crossover model by Volvo, toward three plastic pylons at 10 MPH.
The car's computer, cued by a video camera and laser beam seeing an object ahead, took control and stopped the car, and fast - a classic panic stop.
Also in the car was John Hourdos, a civil engineer and traffic management specialist at the University of Minnesota. He considers the test a success: "There were only three pylons in front of it, which is a much smaller target than a regular vehicle, which means it'll work for a child or pedestrian."
Nearly all the car making companies are poised to introduce these emergency also called invasive braking systems.
For now, the system only works on low-speed crashes. Even so, the emergency braking system is a giant leap forward, says Hourdos.
It marks the beginning of a wave of new vehicle safety innovations.
They include use of more sensors in vehicles and roadways to warn drivers if they're crossing into another lane, or straying off the road or approaching a dangerous intersection.

I was lanning at Zan's and we didn't have a crossover cable, so I rewired this into a crossover and we got 100 Mbps over it. The LEDs on the PC in the background are link and 100Mbps lights for this cable.
