Can I turn a pair of JBL JRX125 speakers into subwoofers by changing the crossovers?

Can I remove the tweeter and crossover and replace it with a JBL subwoofer crossover and turn them into subwoofers? We have 4 JRX125 speakers and really only need two of them so I was wondering if we could turn the other ones into subs? Thanks!


yes you would play lower frequencies accustomed to hearing from subwoofers but the magnet and driver are not made to hit that low and will end up melting the leads or frying the voice coil.


In theory any speaker can be made to run at a lower frequency if given the right signal (the limiting factor being the size of the coil and magnet apparatus). If you indeed removed the crossovers and replaced them with subwoofer crossovers (assuming the power ratings are the same) you would be able to reproduce frequencies down to about 35hz... decent for a subwoofer.

Can anyone post the specs (crossover frequency, etc.) for JBL 2600 speakers?

I found an old pair of jbl 2600 bookshelf speakers. I could not find any manuals online. If someone could post a link, or at least the frequency response, I'd appreciate it. Thanks.


I know you went on-line, but did you go straight to JBL's support area? Here's the link: http://www.jbl.com/home/product_support/default.aspx?Language=ENG&Country=US&Region=USA. See if you can find your product and download the manual. Good luck.

I just want to know what JBL SPEAKER model the 2445 J/H compression driver used?

cause i have two 2445j compression driver and i'm looking for the crossover before i use it.
please help.thanks in advance.


I looked online, but could not find what pro JBL speakers those are used in. It is definitely used in a professional PA system speaker.

You might want to call JBL - they are pretty helpful.

what does a crossover do?

i was just wondering if i need one. in my car i have 2 4"x6" and 2 3.5" jbl speakers wired into my cars system, but i also have 2 mutant 6"x9"s and 2 mutant 5" the mutant stuff is powerd my a mutant 300 watt amp. i also have another mutant amp, a MTPK12-A that is just sitting in my living room till my 15" mutant xxx sub turns up. would i need a crossover for my 6"x9"s and my 5" speakers?


A crossover allows a certain range of frequencies to pass to a speaker or set of speakers. For mids and highs you'd want to block bass to reduce distortion. Likewise when you get your sub, you'll want to have the LPF (low pass filter) on the amp turned on and set just below the highest frequency of the sub.

For instance if the sub is 20-200Hz, then the LPF would be set around 170Hz.

Check the other speakers frequency response to determine what crossover settings you'd need. From there it's all a matter of taste of what sounds good to you.


for me a separte crossover clears out the speakers especially the inside speakers. for me i have a amp for bass a amp for the inside speakers. the crossover sends bass to the bass amp and highs to the inside amp. the built in crossover don't do much you can barley tell a difference. the best ones i use are clarion 3way and kicker 3way. Good luck


Think of a crossover as a filter that removes certain frequency ranges from the audio signal. A high-pass crossover filters out bass; a low-pass crossover filters out high frequencies. (low-pass = low frequencies pass). A crossover might be useful to remove low frequencies that your smaller speakers can't handle; your 4x6, 3.5" and 5" speakers aren't able to handle a lot of bass, so removing the bass will make them sound better and protect them from damage.

are these good speakers let me know before i buy them thank you?

Beefed up low-end from this 2-way box!
This amazing dual 15" 2-way speaker functions as a quasi 3-way: the upper woofers cover lows and mids, and the lower woofers are crossed so they only cover lows-acting as built-in subwoofers. Progressive Transition WaveGuide horn design for enhanced high-end performance and SonicGuard circuitry to protect driver voice coils from feedback and clipping damage. Built with American-made JBL drivers, beefy JBL crossovers, roadworthy MDF cabinets, heavy-duty recessed handles, curved steel grilles, and rugged carpet covering. The JRX100 speakers are built to withstand the rigors of constant touring while delivering renowned JBL sound night after night.

SonicGuard circuitry to protect driver voice coils from feedback and clipping damage is not what it's cracked up to be. Just set the gain right, match the RMS power to the amp and go.

The purpose of the gain is to match the signal volts RMS coming from the source (CD player, etc.) to the input of the amp.

Here is a guide that will help you set the gain correctly http://www.datafilehost.com/download.php?file=6d26c621

You'll need a multi-meter (AC voltmeter), Microsoft Excel and a way to burn an audio CD from an MP3.

Need some help on setting my x-over and my gain?

I have a 12" kicker L7 750watts rms frequency response: 20 - 100 K. I need help on setting gain and my crossover on my jbl gto 1201.1 787watts rms at 4ohm's. If you need more information just ask me and ill get back as soon as possible THANKS!!!

Necessary Equipment
• AC Voltmeter (Digital display recommended)
• CD with a sine-wave test tone recorded at 0dB reference level in the frequency range to be amplified (ex. 50Hz for a subwoofer amplifier, 1 KHz for a midrange application). Do not use attenuated test tones (-10dB, -20dB, etc.).

The Nine-Step Procedure
Step 1: Disconnect the speaker(s) from the amplifier.

Step 2: Turn “Off ” all processing on the head unit and the amplifier (bass/treble, loudness, EQ, etc.).

Step 3: Turn the input sensitivity control on the amplifier all the way down and switch “Input Voltage” to “Low”.

Step 4: Set head unit volume to 3/4 of full volume.
This will allow for reasonable gain overlap
with moderate clipping at full volume.

Step 5: Cross-reference the amplifier model used and impedance load per channel .....below( i did this for you) to determine the target output voltage.
Note: When bridging two channels, the impedance each channel works at will be one-half of the load impedance. Therefore, it is necessary to divide the actual load impedance in half and use this impedance in the chart when bridging two channels. Also, the voltage found in the chart should be doubled.

Step 6: Verify that you disconnected the speakers before proceeding. Play a track with an appropriate sine wave (within the frequency range to be amplified) at 3/4 head unit volume.

Step 7: Connect the AC voltmeter to the speaker output of the amplifier.

Step 8: Increase the input sensitivity control until the desired voltage (determined in Step 5) is delivered. If multiple subwoofer amps are being used, set each one to the same exact voltage and you have also level matched them. If excessive voltage is read with the control at minimum (full counterclockwise), switch the “Input Voltage” to “High” and re-adjust.

Step 9: Once you have adjusted each amp to its maximum unclipped output level, reconnect all the speakers and proceed to adjust the level balance between the subwoofer and satellite amplifiers by turning DOWN the input sensitivity controls of amplifiers that are playing too loudly. Do NOT increase the input sensitivity of any amplifier as this will defeat the purpose of this procedure by permitting excessive clipping (distortion).

Target voltage for your amp 787W at 4ohms(as you listed) is 56.1Volts

setting xover freq.....tun to approx 80Hz and adjust to your liking in bass

JBL GTO1201.1 Kicker L7?

12" kicker L7 wired at 4 ohms 750w rms gonna get a JBL GTO 1201.1 specs for amp look down. Will my sub be able this amp also gonna be easy on the gain. Also i have a cheap 5g schoche wire kit from walmart package says 700w rms and 1400max will this wore be ok for this amp is ok if the wire is a little smaller than what it needs to be will it hurt the amp or just what it puts out for power? Also i have a 1995 ram 1500 with a 120amp alt will i need to do the big 3 for this amp?


JBL GTO1201.1
12dB per octave electronic crossover
~ RCA low-level inputs
~ Full-range preamp outputs
~ Variable bass boost circuit for optimized system response
~ 787 watts RMS x 1 @ 4 ohms
~ 1114 watts RMS x 1 @ 2 ohms 14.4V supply
~ Dynamic Power 1339 watts at 2 ohms
~ Damping Factor: 6.348 at 4 ohms
~ Frequency Response: 10Hz - 302Hz
~ Maximum Input Signal: 6.1V
~ Variable electronic crossover and bass-boost
also my ground wire is smaller than my power should i fix that?


JBL amps from what I've heard are nice. That amp will put out enough power to that sub. I'm assuming you have the dual 2ohm version? As far as the 5 ga. wire I'd go bigger. At least 4 awg. Look at the link below jbl has a chart for the recommended wire and 4 awg is assuming you are only running 10 feet lengths. Personally you could go bigger if you'd like. That amp pulls 115 amps so you need an amp wire kit that corresponds to that. The second link i posted below is a kicker 1/0 kit for under 80 bucks shipped to your door. Last I heard though onlinecarstereo doesn't have them in stock. You won't find them cheaper than that though from what I've been able to find. The amp has 3 40amp fuses so 120 amps is the most the amp will pull. I'd say you need to at least do the big 3 don't bother with a capacitor. The money spent likely wouldn't help your electrical system like changing out your big 3 would and you should be able to do the big 3 with less money. Have any other questions feel free to ask me.

How do you install tweeters and crossovers?

i have a JBL GTO75.4 II and i have to install tweeters and crossovers and 4 speakers i know about the speakers how do i install the tweeters and crossovers???


Basically this is how the wiring goes. Amp to cross over. That goes into your "Amp In" "Amp Out" or whatever it should say. Then just wire up the speakers, spkr plus spkr neg, twt plus twt neg. The hard part is usually finding a spot to set the cross over. You could always set the crossover in the trunk, but then you'd have to run wires alllll the way to the tweeters and speakers.

i have a CROWN XTi 4000 and dont fully understand how to use the crossover feature?

i need help on how to program my Crown Xti amplifiers to both of my JBL 518subwoofers...What I want is to get as much sound from them as possible without worrying about overheating my amp...oh and also would it be the same for my JBL 515 cabs? Appreciate all your comments, as this will be helpful to others.


Do you have 2 amps? If you're running the subs with 1, run it in stereo and set the crossover to "2 Ch Sub" (I think this is the stereo/sub setting).

The 515's are 8 Ohms and need to be driven with about 800 Watts. Another XTi 4000 will give them 675 Watts, in stereo mode. Which isn't quite 800, but it's still pretty good.

Boss or JBL?

I have skimmed my amp choices down to :

the Boss CH600
800W Max, Chaos Series 4-Channel Amplifier
(400 watts x 2 channels) ---max (I can't find the specific RMS)

and

JBL CS60.4
4-Channel Full-Range Amplifier with Electronic Crossover
(Bridged RMS Power 140 watts x 2 channels)

I previously had 2 channel JBL amp that i somehow managed to fry to death (but i still loved the amp)...

Im matching them with 2 10" kicker CVRs (400 RMS each)....

Im a little unsure about Boss products... so any advise???


if ur running 2 400rms subs both amps are a bad choice. u want a mono amp thats 400rms each ch or a mono amp thats 800rms. check your wiring options and see what u can run them at. the cvr's are dual voicecoil 2 6r 4 ohm.

2011 Toyota Sienna Official Photos and Info Car and Driver

While the market continues its current swing from giant SUVs to smaller crossover vehicles—only after moving from vans to those big SUVs—Toyota believes that the minivan market is poised for a comeback. With that in mind, the Japanese automaker rolled out its third-generation Sienna at the 2009 Los Angeles auto show .

Redesigned inside and out, Toyota promises the new Sienna has been reinvented with contemporary styling and a fun-to-drive spirit. A minivan that’s fun to drive, you ask? In an effort to make good on this promise, Toyota has created a new “sporty” SE model with a unique front fascia, side skirts, 19-inch wheels, smoked taillights, and a lowered, sport-tuned suspension. It will also feature unique gauges and interior colors for those racy moms and dads late for soccer practice.

But contemporary isn’t exactly what we’d call the remainder of the range’s new design. Although the styling is a vast improvement over the ripened previous generation’s, the overall look is much like that of a squared-off Venza. It’s not that the new shape doesn’t look good, but we’re not exactly smitten. We do like how the rear-door track has been cleverly hidden under the window.

The 2011 Sienna rides on the same wheelbase as before but is slightly wider and shorter overall. Powertrain options for the range—which includes base, LE, SE, XLE, and Limited models—will include a 3.5-liter V-6 producing 266 hp or the 2.7-liter four-cylinder with 187 hp, both of which are mated to a six-speed automatic transmission. EPA fuel-economy ratings for the four-cylinder are an impressive 19 mpg city and 26 mpg highway. Steering has now gone full-electric, which Toyota claims will “deliver a more solid direct on-road feel.” All-wheel drive will continue to be offered with the V-6 on LE, XLE, and Limited models.

Luxurious Insides

Seating configurations for either seven or eight passengers will be available. All models are equipped with cruise control, three-zone air conditioning, a power driver’s seat, and remote keyless entry. They also include standard safety gizmos like ABS, stability control, and traction control. Opting for the V-6–equipped LE model will get you dual power-sliding rear doors, a power hatch, a backup camera, rear sunshades, XM satellite radio, a USB port with iPod connectivity, and Bluetooth with music-streaming capability.

The XLE adds leather seating with heated fronts, a sunroof, and an anti-theft system. Optional equipment on the XLE is a navigation system with a JBL 10-speaker sound system and a panorama rear camera, and a rear-seat entertainment system with a 16.4-inch widescreen display that can show two different programs side-by-side.

The top-level Limited model will feature luxurious second-row “Lounge Seating,” offering pop-up leg support. Also included are power-folding third-row seats, parking sensors, dual sunroofs, HID headlights, rain-sensing wipers, and a pre-collision system with radar cruise.

While we don’t exactly see the new Sienna being the sporty and enthusiastic vehicle that Toyota describes it as, we are looking forward to experiencing what appears to be a plush new interior. Sales will begin in February of 2010 and pricing has yet to be released, but Toyota says the base 2011 Sienna will be cheaper than the current model, which starts at $25,340.
