Car Audio and Electronics
Sponsored by: SKOB on itunes Discuss sub and speaker setups, GPS navigation, XM radio, and anything else related to car audio and electronics.
ok so i put in my mb quartz speakers...and they are great, but they whine. theres an interference somewhere in teh line. when i turn the head lights on it gets worse. I cant figure out what is doing it. the amp is gournded to my shock tower. all the wires are insulated.
what else can be causing the whining of the radio. when i push the gas(rpms go up) then the whining gets louder respectively.
help..its annoying the hell out of me.
We all get the urge...Saturday early morning...nothing to do till noon... BMW FTW

Umnitza now provides a mechanic to install all parts ordered right in the box! It's their new "Total customer service program" that will eliminate all the haters and keep incompetents from breaking **** and blaming the vendor! When you are all set simply call INS and they will pick him up free of charge.
More specifically, it's called alternator whine. Try grounding one of the RCA cable's (-) connections. It's the metal ring part of the plug, not the center pin. That's what I did to mine at the head unit end, and the whine went away. On some plugs, you can unscrew the plug cover to get to the wires.
When running one of your cables you crossed (over or under) a power lead and it's picking up alternator noise. Instead of grounding at the shock tower find a factory "ground group" (they're all over the car = a bunch of wires going to one bolt connection) Or run a ground from each of your speakers separately = coming off neg side straight to a solid metal ground (non painted surface) and adding another for your amp.

if your amp is in the trunk, what is the problem of grounding it right to the battery? or where the battery ground connection is? And always make sure you polish, grind, etc. the surface you are grounding to so you get a clean connection.
what kind of connectors are you using? copper, gold? gold is the best i believe.
