my speakers are annoying me for the last time. i get a wine that gets louder when i accel. ive moved the rca away from the power and ground, and ive check to see if my ground is good still i get this

 

try getting new rca cables.

 

ground loop isolator /problems

 

ive gotten new rca's still same thing. and i heard that a ground loop isolator muffs your amp. makes the buzz go away but also a great amout of your speaker sound.

 

Unplug the RCA cables from the amp, turn system on (obviously there will be no music) and see if the whine is still there. If it is, ground loop isolator won't help. In that case consider the battery and the main power and ground wires under the hood.

Some of them distort the sound but the better ones don't.

 

Im having a similar issue and thats a great idea that i never though of. Ill have to try that soon.

 

what type of HU
pioneers trash their rca's causing engine noise

 

ive unpluged them and i get no wine. but im thinking about get a rca loop noise thing. has any one used it. ive also swaped head units and i still get the wine so the noise canceler is my last resort.
