i recently soldered the inputs to the bose amp with some RCA connectors and hooked them up to my aftermarket amp. The signals are pretty strong except i get this buzzing sound from my speakers when my car's engine is on. My question is will the Monster Cable ISM201XLN Silencer™ work?

 

meeh416:
You could have a whole host of problems. Did you insulate all the wire? You may need a ground loop isolater in there yeah...but it could be as simple as a poor RCA connection. Is it a whine? And it only is there when the engine is on? If that's the case you've got alternator whine...ground loop isolator and insulate everything.

sup man...its not a whine...its a buzzing sound...ZzzZzzz...and yes it only occurs when the engine is on...=T any1 tried that monster thing before?

 

meeh416:
I assume that device is the same type I am referring to. I would suggest following the suggestions I listed.

i went to get the ground loop isolator. that thing killed the buzzing sound. but im just wondering how does that thing work? is it jus magic?

 

meeh416:
Yes.




Actually no. A ground loop isolator does nothing more than break ground loops you introduced when you hooked your equipment up. Did you ground everything to the same point? Sometimes you cause oscillations in your grounds by not doing that. Think of it as...hmm...one of those little 5 ball structures you see on a desk where you lift one ball and it hits the remaining four, knocking that one up, and back and forth it goes. You creat that push-pull oscillation and it never disappears. The isolator dampens that to the point of elimination.

oic...i have a quick question...did everyone use a ground loop isolator when u spliced the RCAs? or is it just me?

 

GROUND LOOP ISOLATOR!!!


Yes. I had to use one too. I figure it's because we can't ground the aftermarket amp at the same place the headunit is.

Glad you figured that out!
