Gday everybody, I need your help to workout what ive done to my beloved sound system..i have 2 amps inda boot,2 custom made subs, and a capacitor, all came with my car when i bought it so therefore i dont know 2much bout it, anyway i took off the big black wire in one of the amp to inspect as wear n tears is visible and i drobbed it on the big read wire which normally sit next to and it made a terrible spark(forgot to disconnect negative on battery).Now everything works as normal but i dont get any sound.I dont wanna mis my system too long so can someone point me in the right direction of how to ressurect my sound system pleeeeeeese..have i damage the HU or one or both amps??or the speakers??ive checked the fuses on both amp and they look fine.

nevermind.

You sure the fuses are ok?? Do they amps still turn on?

lol. Well something you'll never do again i gather now. Check the fuses on the amp as mentioned. there should be a big one in your engine bay aswell going to the amps.

sometimes looking at a fuse it will look fine, but it will actually be screwed, if possible get a multimetre and check for resistance, there should be none! if it shows resistance the fuse is bugged, also check fuses in engine bay/drivers door box

And or the amps :( Check fuses, make sure amps turns on. If fuse are blown and you replace them and the amp seem to be on. Amp maybe stuff due to the short :(

thanks for the advise everyone, cheers, il check all that was mentioned tomorow as it was getting dark when it happend, and i do hope its a fuse, wil keep yous updated

thanks all for your comment and advise, il look closer at it tomorow as i panicked after it happened and it was getting dark and i wanted to share my pain with someone lol, ive worked out what ive done, i got 2 amps in the boot, one is for the subs by the look of things and the other amp in question has my 6 by 9 rear speakers on it plus other connection which runs to a black box under the driver seat which den has connection to the HU and so on, anyway the Ground cable wire touched the 12v cable wire as i drobbed it and produced the sparking ive got 2 sunvisor, 2 headrest dvd screens and are all connected to this box under the seat and they stil work just no sound, il post tomorow of how i went checking all that was mentioned in all your post, nite nite for now my fellow forum buddies.oh the amp light doesnt seem to be on when i turn on system

U were right TUFFTR had a look under the bonnet dis morning and the big ass fuse on the red power cable has fried, wil pop a new one in disarvo and i hope that was the only damage ive done, i wont be lazy in the future as i like to play and get to know things il disconnect negative on battery everytime as lesson learned thanks all for your time, very much appreciated.

just keep in mind that every time you disconnect your battery, youll reset your ecu, meaning youll have an hour of 2 of stalling every time you stop at an intersection until the ecu relearns a proper idle.

Tis a right pain in the ass.

Next time don't disconnect your battery, just remove that big fuse. ECU will still be powered up, but your amps etc will be safe to play with.
