Those noise filters are not the way to solve your alternator whine problem. Fix your ground, try a different set of rca's, re-ground your head-unit to the bare metal of the chassis.

you have a ground problem, double check them all and make sure you have bare metal, and re ground

If he has a newer Pioneer headunit he needs to ground is rca's to the chassis. Pioneers have a bad problems with that.

quaker is right on the money here.

The noise filters and ground loop isolators are nothing more than a band-aid to cover the problem rather than a cure to eliminate it.

Alternator whine is almost always indicative of a poor ground somewhere in the signal path. It is up to you to troubleshoot just where in the path that bad ground connection is and then remedy it. Could be a bad ground on the HU. Could be a bad set (or sets) of interconnects allowing induced noise into the signal. Could be a poor ground on the amp. It could be all of the afore-mentioned problems.

Find it. Fix it. Done. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Yeah but,

(I've got the same prob)

What if the hu and amp are solidly grounded to the floor, and the rcas at the hu are connected to ground in the unit. There is going to be a loop (and I can't cut the rca shields either).
