Hooking up Two Amplifiers

[njknittle 10+ year member]

Well currently i have one Mono Block Amp for the subs. I want to invest in getting another amp for my mids. Now the only question i have is that how am i suppose to go about hooking up two amps to my headunit? there's only one remote wire on the back of the headunit and ill have two remote wires from both amps. what to do?

Run a jumper from the remote connection of amp 1 to amp 2. or you can split it @ the HU.

So all i would have to do it run a wire from the Remote terminal on the Mono block, onto the remote terminal on the 4channel?

yea... 2 remotes from the HU will work perfectly fine... anything more then that, and you'd want to run a dedicated relay

Personally, I had to run a relay just adding the 2nd amp, for whatever reason... It was sending the HU into protect. But hopefully the same is not for you, and you just run a little piece of power wire from the Remote On of sub amp, to the Remote On to the 4ch. It should hopefully work for you. If it's turning on, then shutting off and not turning back on, the HU is going into protect and you need to run a relay for the remote. Don't worry about that unless you have to though, just try jumping it for now.

If amps are functioning properly, you can connect all remotes in one. If one of them fails in a particular way (happens with Rockfords) you can have your another amp constantly on draining a battery. Relay/Diodes can be a safer solution. Search for these...
