Stereo - No Sound!?

[thorpe84]

after spending thousands on my car stereo i was driving around yesturday with it up loud (35/40) and it just turned off.

i though it might have been one of the amps over heating but if that was the case then the sub should of still been going?

im hopings its the fuse at the back of my head deck?

both amps (soundstream 4 channel and pioneer mono) are not turning on at all!??

head deck is turning on playing cd's ect but no sound is comming through anywhere?

i have checked the fuses on the car (electric 1 and 2 and car audio).

any help would be great thanks

edit, i posted it here because the car audio section doesnt get as many readers

do you have a fuse between the amps and the battery? check the fuse on the back of the head unit.

also check that your head unit's face is attached properly and you haven't accidentally muted it... yeah I know, stupid idea, but it could happen.

yeah there is a big ass fuse between the battery and the amps, it is fine

i have a double din pioneer deck so the face doesnt come off

dont spose anyone would know the type of fuse it would take as i cant find the manual for it, and cbf driving around with my dash all over the place trying to buy the friggin thing, from memory its was a red blade fuse smaller then the ones that are in the car fusebox?

Yeah those are the types... I always thought those were for the onboard amplifier though, someone correct me if I am wrong, but I have never actually blown a fuse in the back of a head unit...

Simplify everything, start with step one... Grab some power (with an inline fuse) and a remote wire from the headunit (if you have all external amps, and they won't turn on, it could very well be this) and run new wires to one amp and see if it turns on... If you can't make the amps turn on like that, I would start to worry...

just test stuff one by one...

to be honest i have no idea when it comes to electronics, i have paid alot for all this shit to be installed into my car and im not confident enough to start f**king around with all the goodies, i would probly end up frying myself.

i know basic electronics but nothing too crash hot

i was thinking, because both amps arnt working it would have to be a power problem wouldnt it? grounding or something like that

[DRD-00F]

That or the remote wire... That tells them to turn on and off, if that got shafted and earthed out, it wouldn't be able to tell them to turn on...

Got any friends that can help you out with checking wires and stuff? You just need to run some extra wires to the amps to see if it is a wire problem... That's step one

that happened to a friends sterio , had no sound but the head unit still had power. Took it to a auto elec and what it was was a wire was not quite crimped right and the whole unit stops working as a safe measure. Btw this was a alpine headunit

was justs kimming thorugh the thread, does your head unit still turn on? get a test light or DMM, check for power at the thick power cable on the amp and the remote wire (little one next to power wire) on the amp, if both have power your amp(s) are gone (if the headunit doesnt turn on, there wont be power on the remote line)

the inline fuses may look alright, but make sure your getting power at the other end, same thing happened to a mate, fuse looked brand new, still wasnt passing power though

edit - there will also be a fuse under the dash somewhere (cant remember for R33's specifically) that supplies power to the headunit, try that one first if the unit isnt turning on

head deck still turns on, dont have a multimeter but will get one soon

all the fuses seem to be okay =/

The fuses used are pretty beafy, but when they go, the break can be quite small. I had the fuse go on mine, and by looking at it, you couldn't even tell. If you are getting a DMM you can test the fuse with that. Otherwise, I'd recommend buy a fuse and replace the current one. They are only a few dollars, so if it isn't the problem, it hasn't cost you much, but could save you money in the long run.
