Here's the wiring specifics for both amps:
- 8ga power from mono (350W rms) amp --> battery
- 8ga power from 4channel (220W total rms) amp --> battery
- 2 8ga ground wires from each amp --> same ground point
- 2 remote wires from each amp --(crimp connector'd)--> remote wire to deck
The only reason I have two separate 8ga power wires instead of a 4ga/distro-block setup is because I added the sub about a year and a half later, and I went with the quickest/easiest install method by running another 8ga wire to the battery for the sub amp.
The amp is the alpine mrv-f340, in case that matters. The LED brightens, then immediately dims every time.
