Amp help!!

[devils_fuel]

My current amp worked before I swapped it for a second hand amp, the second hand amp and now my original amp doesn't work! I have checked all fuses and connections and they're ok...I'm stumped!

I've even disconnected the battery so the stereo can reset its self

[MarkTD]

Has it got a good earth connection?

[devils_fuel]

Yeah, like I said it worked perfectly until I swapped amps, now neither amp works

Could possibly be the remote wire from the head unit, try bridging the +'ve to the remote and if the amp works then you know it's the remote causing the problem

I hadn't thought of that fella ...I was thinking about ripping it all out and starting again with new cables, hopefully the amp works
