Hi, Based on your post/description, three possible reasons: 1. There is no power going into the amp. The fuses may be good but there is no +12VDC in the big red wire. You have to use a voltmeter to check if there is 12V at the end of the line/wire before it goes inside the amp. In some cases, the fuse might be good but there is corrosion on the fuse terminals and the metal contacts of where it is placed; 2. There is no switching signal to activate/power on the amp. In some setup this is a blue, yellow or orange wire. This can be activated by either the ignition switch of your car, the headunit/stereo, or even a manual on/off switch. This has to receive a 12V also to activate the amp; 3. Internal fault of the amp. The big red wire has 12V, the fuses are good, there is signal 12v to activate amp, but still no power; there is something wrong inside the amplifier. It has to be opened up and diagnosed. This may involve component level repair, circuit analysis, electronics and soldering so you might be better off seeking the services of a qualified professional. Hope this gives you some ideas and work out for you. Good luck and pls post back how things turn up. Kind regards.

The Audio system on my 2005 Solara Convertible just died. I checked and replaced the 25 amp fuse (the old one still looked good), but still no power. What else should be checked?
dead as in all functions and modes dead, all.
?
well it can only be 2 things
1: no 12vdc to head, (use a 10 buck voltmeter from walfart>?)
2: head end is dead.

25amps is the wrong, fuse. even 10 amps is good for 140watts.
the fuse is stated in the operators guide lost that?
some cars its mark,, RADIO.
the fuse that looks bad is
the fuse that looks good,can be , in fact. bad. what most techs
do is use ,yes, the voltmeter again, to measure bothsides of fues
keyon, radio on, to check all fuses related to radio (audio)
12v on both sides wins
if 12v makes it to the Radio and amp (if external amp then that too must have power, for sure) then the radio is bad, or amp.
if the radio scans and finds stations(not stated) then the amp might
be bad or lost power.

radio 101, over and out.

Is there 2supplies to radio cd
sure , but they have many radio options on all cars.
stock and not stock and many stock too.
yes, main 12vdc power runs the whole radio. and memory power
and if it has an outside amp ,it too has power, 12vdc supply power.
and fuses. all power feeds in car are fused, (cept starter)
so fuses are first.
id the dial glowing or not (data, not just back light)
one other power feed to radio is parking lights back ground lights.
called illumination.

post symptoms first, fully, good the bad and the ugly.
all radio symptoms and we can advise you ,easy
even bench testing is easy.

Jbl radio A56840 loses station presets and no volume
Toyota vehicles have a fuse in the kick for the amp and sometimes there is located under the hood ... This is the switch turn on for the amp ... And 1 of the fuses is most likely the memory or constant power. B sure to check all fuses ... I do not have AllData pulled up . If the fuses are all good the amp or radio may be bad ... Or both ... Be sure to check all the fuses ... Many times I get clients that say allthe fuses are good and it is still the first thing I check ..Usually is a fuse ..Good Luck

I accidentally hooked up the battery, reversing the polarity. I corrected the screw-up, but now the radio and interior lights will not come on. Fuses look good. any suggestions on fixing the radio &...
Ouch! Okay, do you have a volt meter? If so you need to check the voltage at your fuse box to make sure that you are getting power to fuse panel If you are getting power to the panel, then you have to diagnose the power issue from the fuse panel to the radio and dome lights. All the lights not working? The radio may have an in-line fuse as well. If you don't have a volt meter, go get one.

I bought a 96 jeep cherokee sport & the interior lights only come on for the front passenger door. the three other doors & the hatch dont turn on the interior lights & i cant find any fuse box...
Can you turn on the lights with the Interior light switch?. If a light works, obviously the fuse is good. You will need a wiring diagram and a test light to figure out where to start.

Have Power going to the amp. Amp does not turn on. Do i need a remote? Bought vehicle with amp in it. LXA 600 Power light does not turn on.
you need to make sure you have 5 things.

1. power connection to the battery/amp
2. make sure you have a remote line radio/amp
3. make sure you have rca's radio/amp
4. make sure you have a ground amp/car frame ( scratch paint away for good contact)
5. make sure the speakers are connected to the radio.

if all is ok then check the inline fuse from the hot wire from the battery is not blown and the fuse on the amp is not blown.if so replace them. with the proper amp fuse.

My 1990 toyota corolla tail lights and dash lights stopped working after i hooked up a stereo and sub and amp system...i checked the fuse and its good..i cant find any wiring problems..help? anybody?
which fuse did you check. verify the wiring to the radio than comes from the light switch to the radio. if all this worked before , then it has to be work that you have done. the only link from the light switch to the radio is for inst panel dimming. first disconnect that wire and ck fuse for tail lights. make sure there is power on both sides of the fuse, use a test light.

Radio/clock will not work. fuse 10 amp is good
There is usually 2 power sources to that stereo, one for when key on & one constant for radio memory & clock, you know that right? Check for that& Make sure it has good ground also. Use another ground source from back of stereo to metal just to be sure, if no luck, probably time for new stereo.

No dome light or radio
It's the IOD fuse. Trust me, I just fixed the exact problem on my '98 not ten minutes ago. The fuse is located in the fuse box inside the driver's side door. It will be the fuse on the bottom and toward the front of the panel with a black cover over it. Just pull the fuse holder straight out and snap the hinged cover forward to expose the fuse. Just a standard 10 amp automotive fuse and you're back in business!
