My audio upgrade winter project is coming along now. I have already replaced all 4 cockpit speakers with JL Audio M650 CCX speakers. I have the JL Audio M101 B5 subwoofer on order and should arrive any day now. That one I am going to have to cut a hole for and mount myself and it is going on the wall under the cockpit port side seat, plenty of room for it there.
I have made up my amplifier section and this piece here will be mounted under the sofa bed in the cabin. The old amp was there so speaker wires where already there, the only wire pulling I needed to do was for the heavy gauge power wires and the extra speaker wire for the subwoofer.
I was able to find a small solid state relay board which I am using one relay to turn on the 12 volts to the cooling fans and the other relay turns the 12 volt signal to the remote on feature of the amplifier and sub amp only when the radio is on. I did not want to drive the fans directly from the remote output of my stereo since I did not know the current capacity of this output. This was a safer solution, so my radio remote feeds the transistors that turn on the relays, the relay contacts then turn on the fans and the remote on signals to the amps. With most of the wiring done on this board and brought out to the terminal strips it makes it easy to install and remove if needed.
