Feedback in Subs Options

[Random_Stranger]

It never really did that before, can anyone tell me what that means and how I can fix that? If I undo my seat belt, sometimes that breaks it but it comes right back, or if I lower or raise my window.... It's the craziest thing, but I hate hearing it when I accelerate thinking I got a supercharger or something. It's really annoying.

A lot of mis-information in this thread!

To clarify:

-for a SUB AMP, it is not important to run rca's and power separate. Subwoofers operate at too low of a frequency to be affected by noise/interferance from the power wire. However, a 4 channel amp that powers interior/coaxial speakers will definately need the signal and power wires ran separately.

-Alternator whine will ABSOLUTELY be consistant with engine rpm! As your engine spins faster, your alternator will obviously spin faster too.

-Ground loop isolator's are usually a last resort, after you have troubleshooted every other component in the car.


As other's have said, it can be a number of things
-bad amp ground
-RCA cables might be pinched/exposed
-the head unit RCA pre-outs could be bad
-the RCA inputs on the amp could be bad.

Any questions RandomStranger, feel free to pm me.

just remember you better take into an account peoples setups, not everyone can afford or has resources to have a seperate sub amp. Some people run all their speakers from one amp even the sub. I've been doin this for 12 years. Im not a pro but i don't have problems with audio equipment because of my setups.

my concept, is eliminate any possibities so for sure you don't have to worry about it all. most of all really, is it gonna kill you to seperate the wires.
