I am using the Stinger Bullet series RCA's so they are a little bit higher quality than most of the RCA's out there. Not top of the line, but by no means close to the bottom. I'm using 0 gauge Stinger Expert power and ground wire from the battery as well as Stinger Expert 4 gauge to the amps power and ground.
The only direct way I can find has me crossing the battery cables running from the front of the boat to pod and engine. I also would potentially be crossing the power/ground wires to the amps. I would be able to cross them at a 90 degree angle but is this okay?
By the way, I have a Kicker 800.4 and 600.4 in the boat or on it's way in the boat right now. I also have a Kicker KQ5 pre-amp on the way to run the tower speakers. Future plans are to add a third Kicker 1200.1 to run two subs.
