Ok, so I'm putting my old Clarion deck in my buddy's 1990 Doral Concept (boat)....
There are two wiring harnesses in his boat's dash. One is for power, the other is for speakers. The speaker harness has 5 conductors. 4 of them are labelled: RF+, LF+, RR+, LR+
The last wire has no label. Now, I remember old car stereos (installed in a car) used the car ground as a common negative terminal. Newer decks have obviously gone away from that with discrete positive and negative leads. But how do you hook this up in a boat? Especially as a boat's, ummmmh, chassis..... is not grounded. I hooked all the positives up to the new deck positives, and then one of the decks speaker negative leads to the fifth wire in the boat's harness, and I do get sound from all the speakers, but the back ones are very quiet, even with the fader adjusted evenly.
At a bit of a loss here....anyone know? Short of running new speaker wire....

yeah your best bet will be to run new wires.
Without running new wires I got nothing either

If it is IMPOSSIBLE to run new wires, I do have something for you, but it will cut your output power in half. From 17 watts per channel to around 8 watts per channel.
