hi all

just a question how do i get rid of the engine noise through the speakers the speakers are all hooked up to a rockford p4004 which when you turn up the gains on the amp you get this noise through the speakers

should i use some sort of rca balancer bit confused!

btw all the earths are connected properly and have been tested including from the back of the head unit

any help would be appreciated!

thanks guys!

Check earths on head unit RCA grounds.

time to whip out the shorting plugs i think....

What are shorting plugs?

Shorts out the inner of the rca socket to the outer.

Why would you want to do that?

tried that! what other filters are available to get of this also when you turn it right down it lets out a "pop" through the speakers!

I already told you what the fault is in the first reply to this thread.

Get the head unit checked by Pioneer.

by shorting out the inner and outer of the rcas u can then plug them inot ur amp and if it buzzez u kno its in the amp
if not plug em into the end of ur rcas say at the HU(will need femake 2 fealmale adapters) end and it buzzez but not when u plug it straight into amp u kno its ur RCAs introducing noise.
