I'm starting to lose it.. I'm trying to troubleshoot some alternator whine... Things I have:
Pioneer 4000dvd..
Triple Shielded Klarity RCAs..
Big 3 in 1/0..
Kappa Amps
200 amp dB electrical alt
Things I have tried:
Swapping unit to a JVC 810 ( Pioneers known to have RCA issues )
Grounding RCAs
Running RCA right from unit down middle of car to rear ( to eliminate chance of small power wire I have on RCA side ( but they are triple shielded so just ruled out that because it still whined )
Things that are weird:
When I do a rev my voltage hits 15.4 which throws amps into protect. ( 15 volt cutoff ) So i'm thinking that increase in voltage is spiking everything and making the whine
I'm not sure if I did an alt ground with 1/0 so i dunno if thats making it spike
What should I do? I just want to have no noise... and everything to work properly... What i'm thinking is take out this alt, throw back in stock 120 and roll like that. I am only running around 1200-1300 RMS and I have big 3 maybe get a better bat.. ANY INPUT IS NEEDED I WANT TO GET IT SORTED OUT.
