i had the same problem mate, turned out to be a bad earth off the amp, so check the earth i had to change were it was earthedand now mine is fine :)

bonjour again guys, found the fuse box cover, found broken fuse - this fixed the horn and interior light i gues they on same circuit. Then decided to test remote wire on amp and it wasnt giving signal so i started to rip apart wiring from back of headunit followed it to the amp. I ofund that someone gay had managed to cut the wire slightly making it intermittent so i re-wired it all up and now all is ok!!! cheers and let this be lesson to u be careful on wireing near the folding rear seats

could be a relay , have you got a corsa ? if so can tell u were the fuse box is, then you can check the fuse's and relays

thanks for the input guys its a sony mp3 not too old about 3 years but it has a dodgy problem on the scree but this is due to the contacts on the face off surely doent affect processing etc? connections are ALL connected i assure u all. but what of the links between horn and interior light? im thinking of a fuse but havnt a clue where they are!

I had same prob - tured out to be the HU. How old is yours?

have you got your amp remote wire connected to the correct wire at the back of your stereo

where are you taking your feds from for your amp and that?

dodgy connections is my guess

ttt!!!

i have had this reoccurring electrical problem where my sub and amp are working great then its not powering up amp, all wiring is secure and its odd becuase my horn and interior lamp have stopped working too. Its done this before and I disconnected sub and amp and gave to garage. £300 pound later and an MOT horn and light was working but only recently i noticed amp was on so wired it up n all was fine. Last nite amp and sub was intermittant whilst fronts are fine and now sub and amp not working PLUS inerior light and horn not working!!!!


HELP!!!!:(:wave:
