[Andy099]

well i been working on this car audio all night..but to make it short i connected my stock cd player backin to rule out and issue

but the rear speakers aren't playing...the front workfine i make sur ei connected all the connections to the back of the unit and nothing makes sense.....i checked all the fuses and its all good to go...i dont see a fader/balance control to have all the sound up front

i even plugged up a stock speaker to see if my rockford fosgates are blonw..any help is appreciated

check to see its any wires are grounding out against the chasis. use a test speaker and test all the channels directly from behind the radio.
