Yeah, alternator whine can be tough to deal with. I know where to look first, because the connections from the factory low-level signal to the amp is a pretty "getto" setup that is just asking for trouble. Just did that to see that I had the right connections, and will do a different setup the right way. If that doesn't work I'll start looking at other possibilities.

Anyway, thanks for suggestions.


alternator whine...oh god.
I've been through this. but am far from expert.
-often remedied through proper grounding of head unit or amps. Check that amps are grounded properly or have a seperate ground run back to the battery. see "ground loop" stuff on web.
-may not apply to you but a head unit with higher voltage preout often helps, 4-5 volts.
-bad or old battery can also be a factor.
-coils may be used at the power source to amps, for ultimate solution, though suboptimal as it will increase resistance of power to amps.
