Somehow the Remote-on lead on my amp doesn't work anymore. When connected, the amp stays powered on regardless of the car being on or off. I've tried everything to fix the problem, measure all the volts using a multimeter, and have come to the conclusion that it's the Remote-on lead on the amp itself. The amp still works fine, and powers the subs fine. It'll just drain the battery unless I connect it.
So my question is, to avoid having to purchase another amp, can I use a relay and put it in the 12V power cable (8ga), run the remote-on wire to it to trigger the switch, ground the relay, and then run the other part of (8ga) 12V power cable to my amp? Would this work? I'm not wanting to add the relay to the remote-on wire itself, I want to add it to the main power wire, so the amp would NOT have the remote-on wire connected to it period, yet the amp would turn on and off whenever the car did so. Any help would be greatly appreciated!
You can run a wire from ignition (red) wireon the deck to the remote input on the amp . When deck is on, so is the amp.

See, the remote input on my amp is apparently messed up. I believe it somehow shorted to be always enabled, so the amp itself is always powered on regardless of remote input or not. The amp powers on WITH JUST the power and negative hooked up to it. The problem is with the remote input on my amp, not my HU, not my wiring. I just wanted to try a relay before purchasing another amp.
If you have to kill power to the amp like that, use a high amp circuit breaker like
Stinger SCB135.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
you can use a relay inline on the 8 gauge to switch the amp on and off. just make sure that you get the appropriate amperage rating on the relay. do you know what the current draw is on the amp? or if the amp has fuses on it, what size are they?

No I would not relay the 8 ga wire running to the amp. A standard relay is not meant to hold that kind of current. Are you sure that you have your amp wired correctly? Did you remove the radio disconnect the remote wire from the amp and check for 12volts when on and 0 volts when off.

Dreaming about thing that I want only to away to find things that I can't have... But that's life!! And I deal the best way that I know how..Down shifting and taking it to the red!!!!!
Yes you can and if you want to keep your amp without it getting fixed, install a HIGH AMPERAGE relay like the Scosche PMBC200.
