Speaker Whine

unkone · 04-07-2008, 01:13 PM

Just got done replacing my rear 6x9's, and I notice there is an low whine coming from them when the music is off. I grounded the amp to the battery ground. Is this a good idea? Where are you guys grounding your amps to?

It could be my rca's to I am not sure if they are correctly shielded.

how long is your ground wire? also i would check the rca's.. one of mine broke at the tip and i got the whining noise till i replaced it

Try the easy stuff first before pulling out the deck again. does the wine come from both speakers? if not, try switching the RCAs on the amp and see if it changes, or even disconnect the RCAs and see if the wine is still there

The whine could also be caused from a poor ground on the head unit. If of course you have an aftermarket head unit.

grounding your amp straight to the battery isnt bad they say you should run a ground fuse reason being if your battery ground to chassis dies its gona search for ground elsewhere which at that point is the ground through your amp.... and looks like everyone hit the nail on the head with wine

amp ground to long or just not good enough
head unit ground
rca cables

I cut about 12" of the ground and that did it. Thanks!
