deffo the ground somewhere, check headunits ground, battery ground and the 2 amp grounds.
make sure u use proper grounding terminals too!

sounds like a dodgy ground mate....double check your ground, or move it to a better ground.
failing that, get a ground loop thingy (forgotten name...its too early :lol: ) - can get them from halfords and see if that works :)

na its like a zzzzzzzzzzzzzzzzzz and it changes with the revs of the car

When you say interfernece, do you mean the speakers and subs are making 'crackling' noise...? Cause i had this in my System, and it was because of the REM leads, so all i did was split it at the head unit, and run two wires down, to each amp.

runnin the 1 from hu to big amp then bridgin it to lil amp

do u have 2 remote leads from headunit? or are you running the REM to one amp, then straight to the other one?

very secure

You checked all connections? is the remote lead secure?

right sorry for the wank diagram but when ignition goes on i get terrible interefence tried moving the power cable over but its still there i wa thinking its because im bridging the amps and there right next to each other???? HELP its winding me right up, what should i do



cheers:thumbs:
