Wiring question

[drewkeen]

I am trying to install a Sony CD player in a 1995 motorhome. The motorhome has a ground, constant power, ignition power, 4 wires (one for each speaker) and a couple of more things on it stock. The Sony has 2 wires for each speaker (8 total), the two power wires, a ground and some extra remote wires, etc. How do I connect the headunit properly?

4 wires (one for each speaker)

Are you sure it's not; 4 wires (2 for each speaker)?

I have had some old cars where they use a common ground for all the speakers and then just run a hot to the speakers.

Yes, I am 100% sure that there are 4 speakers. It is a 1995 model so there may be a common ground. Would I just bundle all of the ground wires together and connect them to a common ground if there is one? Any idea what it would be abbreviated as in the wiring diagram?
