I've just rewired my rear speakers from the head unit, everything ran fine when i tryed it for the first time. Now the speakers will cut out, leaving on the subs. I've double checked the wiring and everything is tight and taped up. Any suggestion to the cause of the problem would be appreciated.

Solder your connections, don't just twist and tape. When I installed my first deck, I used those electrical twist cap things and just twisted the wires. It worked ok for the first few months, then my front left speaker didnt work, connection broke. Soldering guarantees you a solid connection unless your rip the two wires.

my mistake, the wires are actually butt connected to getter the taped over the wires and connector.

So i think i found the problem,as weird as it sounds i disconnected my radio antenna cable from the headunit. Theres been no problems since....
