Wiring two amps, quick question...

[purerx7tt 10+ year member]

Just picked up a denon DCA-660BL for my rainbow comps. I already have a hifonics amp powering my diamond subs. Now how do I wire this to the headunit. Do I connect both remote turn on wires together and than connect that to the headunits remote turn on wire? headunit is alpine cda-9853 by the way. Another questions is, its a 2 channel amp and I need a 4 ohm load for my rainbow comps. Now do I run one - and + to the left side and than another - and + to the ride side of the car? DO I have to wire anything special for a 4 ohm load, because when I wired a 1 ohm load it was a little bit different. Thanks for all your time.... Install pics of it in my 93 rx7 soon to come....

You can tap into the same turn on wire.

And yes, as long as the comps are 4ohm (and they should be) you just hook up the +-.

ok thanks one more quick question, I did not get a manual or anything, what reccomend size gauge for power? It does 120rms x 2 at 40hm

8ga. would work for that.

8 gauge should work fine if you have a distro block from the other amp just use that

ya remote should go connected to headunit remote( should be blue wire) yup your gonna need 2 sets of wires- one for the right side speaker and one for the left . you mentioned the amp is a 2 channel amp just make sure that when u hok up the speaker leads to it the left gets one channel and the right gets the other one thats left over.

For the remote wire deal, all I did was run the wire from the HU to the Amp and took another piece of wire the same size, twisted them together, and put it in that amp and ran it to my other amp.
