I wanted to install under the helm because the HU is there and I was going to use the power run to install a fuse block at the helm and connect the HU to the same power source.
I tried to fit the amps on the starboard side farther back - but they interfere with the armrest/cup holders on that side - so that's a no-go.
My existing battery is on the starboard side under the rear seat - and there's a spot for another battery on the port side - on the opposite side of the v-drive access - that's where my stereo battery will go. See here:
Now I'm thinking about moving the amps and sub to the port side storage area. I've removed all the seat backs from the boat so I can have access to see what works best. You can see where I have the amps sitting - I'm thinking about that spot to mount now.
If i do this - I'll need to get long RCA cables from the HU to the amps and run a separate power line back to the helm side. I'll have to try to find a spot to run under the floor at the helm from the starboard side to the port side. Not sure what else to do. Any ideas?
