    2007 Camry XLE
    I don't have any audio output from the jbl 86280 0w390 amplifier. My left rear speaker blew and became very hot. I cannot access the settings of the speakers from the dash board - it appears that there is no connectivity between the head unit and the amplifier. Is there any way to reset the amp or are there any fuses on the amp itself. I have checked the three fuses in the car's fuse boxes and checked the battery - no problems found. Should i try to find a replacement amp and install it? All help is most appreciated.

    What fuses should I check to try to determine what caused the fault (2007 Camry SLE). I don't want to install a new amp without knowing (if possible) the cause. Anything else I should check prior to installing a new amp....should I remove the connections on the battery prior to the install of a new amp. Appreciate your help and want to restore the audio.

As you said "the left rear speaker blew and became very hot". This is a symptom for problems at the amplifier stage (burn out internal amp parts, not protected by any fuse and giving DC output power at the speaker may cause this exact kind of problems at the speaker). I suggest a full check for the JBL amplifier at a service center. I don't suggest to use this amp at another speaker. This may destroy this speaker also. Depending on the exact kind of problem at the amplifier you may have to check the wiring between the amp and the burned speaker also, before you install the amp back to the original location.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.

    The possible fault connection you have to check out is the cable from the amp to the speakers. Verify that there is no short circuit between them. Also check the speaker cables for possible damages at the outer insulation. These could cause a problem. If this is not the cause for your problem, the next suspect is the too much power at the speaker, or internal amplifier's error. No fuses are responsible for these problems. I don't suggest to disconnect the battery, this could cause a reset at all the settings for your car (including radio cd player). Just connect all the rest connections to the amp BEFORE the power supply connector, so that the power connector is the last one.

    In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.

Hi you might need to do some troubleshooting... may not be from the amplifier,might be from the speakers too or any where...

Its the power transistors that would be affected by low voltage. It delivered till it finally gave up 'cos the output wattage to be generated at low voltage means more current flowing through the equipment. This high current will adversely affect all small solenoid valves & transistors and IC's. Even failure of one section of any IC is rarely detectable with the naked eye. It has to be thoroughly checked with a multi-meter to assess the damage correctly.



First check and sure you have battery voltage and twelve volt turn on on the remote term. of your amp. Be sure u have a ground also. Next take your speaker leads disconnect them and pop them with a battery, and make sure it pops. I(f that all passes you need to make sure your amp is getting an input signal because you could have a bad rca cable.

If the speaker only cuts out sporadically verify that the connections are all good. Cutting out is usually caused by a loose wire connection or an old connection that is corroded and shorting out.

If you cannot diagnose the problem on your own, you should take your vehicle to a professional.

Be careful working with vehicle electronics you can be shocked.


Check the Power

car batteryThe first thing you should check is the power. In my case, the red power light was coming on so the unit had to be getting juice from somewhere. I have a new battery and my vehicle always starts fine, so I didn't think it was a battery problem. If your car battery is getting old and especially if it seems sluggish in really cold weather, you may consider buying a new battery if your amp is having trouble.

A properly wired amplifier should include an in-line fuse on the cable that runs from the positive post on the battery to the amp's main power input. This is to prevent the amp from being overloaded or 'blown' and will save you a lot of trouble in the long run. I checked the fuse on my cable and found it to be intact although there was some black charred marks on the connectors.

Before you unhook any cables from your amplifier, make sure you disconnect that in-line fuse. Otherwise, you'll be holding a hot wire going straight to the battery and it can be dangerous, especially if it accidentally touches any other metal inside the vehicle. I know this from experience.

After checking the fuse and connections, my amp and subwoofer still didn't work, although the light showed that it was getting power.
Check the Ground

Improper grounding is one of the main causes for an amplifier not working properly. The most common place that people ground the amp is by running a wire to one of the bolts that holds down the front seat. That's how I have it wired in my truck. What's most important is for that wire to make good contact with the metal. Often times a lot of paint can interfere with the connection, and it is recommended that you wire brush away any paint to expose metal where the ground wire is connecting. I did this on mine, but in a way that was not at all conspicuous once I put everything back in place. Be careful not to scratch up the inside of your car.

Hi, I bought a new JBL SCS 140 system with amp HK


Fuses blow when something is shorted. In this case it will be a semi-conductor of some kind. If the device uses IC for the main amplification then you are right to be worried!

The 158 amp is totally unsuitable for the JBL.
This is the specification of the JBL:
  • Recommended Amplifier Power 10 Watt
  • they are also 4 Ohm speakers.
  • 158 is: Output Impedance / Channel
    8 Ohm.

2007 solara convertible got wet from roof open all radio 'not jbl' functions seem to work cd everything no sound . could a fuse have blown if so where?


If you have functions but no sound, its unlikely that there will be a separate fuse for the factory external amplifier. Have your owners manual? It has an appendix with a page number to the relevant fuse locations

2007 toyota camry and no sound


I have a 2007, Camry XLE, V6.


Thought I post this as some of you might be looking for an answer.


So, if you recently overpacked your trunk, you might have knocked a bar in the trunk loose. If the stuff in your trunk presses the bar against the rear speakers, it will short circuit your JBL amp located under the front passenger seat.


This happened to me and I smelled some electrical burning while driving. Also, I felt an electrical field in the car. You should bring it to the dealer immediately, but they might quote you some expensive price.


If you want to buy time to research like I did, you need to first move your passenger front seat to the most forward position. Next, disconnect your battery by disconnecting the negative (black) wire only. You have to disconnect the battery because even if the car is turned off, there is an electric current going to the amp.


Next, pull off the black cover of the amp. you need to disconnect the three wire inserts by depressing the button on top of each wire. Then, disconnect the ground wire by loosening the screw. Finally, you can unscrew the main screw that keeps the amp in place.


Be careful as I believe the amp still has charge in it. Don't leave it anywhere as I left it on my desk and a few days, I heard some burning noise and then a strong electrical odor. I ended up leaving it out in my back yard.


The other thing is that you need to check if your fuse is blown under the car hood. Most likely it is. You need to go to the car store and buy a micro profile fuse. There are three different fuses out there and the one you need for the Camry is the micro profile fuse one 25a. The back cover of the fuse box will tell you where the amp one is. You can tell that it's burnt if the connection no longer is bridged together underneath the plastic. Inside the fuse cover, you should have a tool to help you pull the fuses out.


I ended up looking online for a used amp with the same model number, 86280-OW390. Although, this model has been replaced by a newer one: 86280-OW391


It costs around $665 if you bought it new online. I found a recycling used parts place for $220. I read someone was able to buy it for $125. Ebay was selling it for $350+ when I looked.


So I figured I'll buy the used one and see if it works. If my speakers blew out, then I would have to replace everything. I would have sold the old one on ebay for the price I bought it or more.


In the end, the old one worked from a 2009 camry and I am pretty happy.


Last, I wrapped electrical tape around the bars in the trunk where it could have made contact with the speakers. There are two bars and I wrapped the possible contact points there too just to be safe.


I hope this helps someone out there. It was a headache to do, but glad it's resolved now. I also read that some 2007 camries can catch on fire. This was definitely a potential candidate.

Jbl gto 75.4 right channel not working


Hi

It's rare that 2 channels will fail simultaneously, are you sending 4 signals to the amp or just 2?

If you are sending just 2, perhaps the problem lies before the amp in the cabling to it, or the output from the headunit. If you are sending 4 signals then there may be a fuse in the amp that drives 2 channels out of the 4. Of course this may be the case should you just be sending 2 signals.

Bloon Fuses!


You don't need schematics to replace the fuses.
Open the speaker unit by unscrewing the back. The fuses are located near the on/off switch assembly. Replace them and screw the the unit back together.
To avoid blown fuses, try lowering the volume.
