Weird stereo problem

[Cheese Monkey]

So my (intended) set up is -

LG head unit

Amp + sub

2x door speakers front channels

2x 6x9 speakers rear channels


So, I have connected everything up, but as soon as I connect the 4th rear channel I lose all sound to the speakers (still and always get sound from sub). It happens on both sides. This happens even with the rear speakers disconnected, if I only connect the rear channel cables as soon as I connect the last one I lose all sound from speakers again. Tried swapping cables, speakers, sides, disconnecting the amp, everything I can think of.

The only thing left is a dodgy head unit? Seems like it just wont do 4 channels.



I dont know, I'm stumped. It worked for 2 min . Was really enjoying wiring the sub and amp in n all.

Going to parell up 3rd channel and run that until I can get it sorted. Bit lame, only getting half the power output then

Does sound like faulty head unit, but could have been caused by faulty speaker, or short in speaker cable

Both speakers work fine and cables are literally brand new

Time to hit ebay I think

Having said that could a faulty speaker cause that but still sound ok? If one of them is shagged it hasnt taken anything else out because I been playing with both of them for ages!

Nailed it

Was a speaker cable trapped under the 2 front seat catch and earthing out
