Is there any better way of hooking up the remote wire (REM- blue wire)other than going from the headunit to one amp, from the 1st amp to the 2nd amp, from the 2nd to the 3rd, and from the 3rd to the 4th?
Its just seems kinda riggish
Don't use the headunit amp remote to trigger all 4 amplifiers - there's a good chance you could kill the headunit by exceeding the amperage rating for that amp remote.
The best way to do it would be to use your amp remote to trigger a relay, then use the output of the relay to turn the amps on.
search on
www.bcae1.com to see how they use a relay to control fans for amplifiers - essentially the same applicaiton - just make sure you fuse it all properly.
