ok so i put a new cd player in the car today and i hooked eveyrting up righ tbut yet only 1 of the speakers work the front left one. my rears i think i hooked up the wires wrong but then i swapped um and wouldnt; work. checked all wirde and they all have good connectiong sbut still no sound out of them. any idea's

 

if you check the fade on your deck and its set properly i would quickly take out the back speakers are wire them yourself directly to the HU to see if they work or not...should take about 10 minutes and a few feet of wire.

you can also test the wires by quickly taping them to a low voltage battery (less than 9 volts) you should hear a little pop from the speaker but be carefull not to hold the wires on the battery for more than a split second

 

thanks boomin boy i planed on getting a speaker and hooking it up directly to the HU and seeing if its the wire going to the speakers
