It seems that regardless of how I hook up the wiring there is still no sound coming from the speakers behind the seat

Did you have sound behind your seat before you changed the head unit?
The 6.5 subwoofer behind the seat would pit out low frequencies only.
When I hooked up my kenwood marine 558bt I used the wiring harness adapter and not have to hookup rca's.
I upgraded my factory 6.5 to the pyles, just alittle modification to the basket, makes a difference.
Didn't the base model of 05 and newer not come with the 6.5 subs behind the seat?
