Is car stereo always this frustrating?
I've about had it with my stereo install. Perhaps a few clubwrxers with more know-how can school me so I don't go ape and just destroy everything.
So I have the dreaded miscelaneous car whine and buzz/hum sound. I've isolated that the culprit is my basslink subwoofer.
So here's the low-down. I have an amp connected to my headunit. There is a very very slight hum at volume 0, but I can live with that, since you can't hear it once you turn the music above 0. However, my basslink is introducing a lot of noise in the system.
Here's what happens... whenever I connect my rcas to the back of the head unit, I get a strong humming sound, which is greatly magnified when I start the car and rev the engine... the so-called alternator whine.
What's odd, is that if I touch with my bare fingers the rca plug on the back of my headunit, I get the same hum, so now I'm not so sure what the problem is. I have my amp grounded in the back with a big 0 guage ground wire to a bolt I screwed in (sanded and prepped). I also have my basslink grounded to the same bolt. I've heard it's better to ground to the same point.
My headunit is just grounded to the stock ground wire. I notice when I touch any rca plugs (metal part when connected to HU), it gives me a hum, but when I touch the rear or subwoofer rca plug of the HU, it's even louder.
Everything was fine before I introduced the basslink. I've noticed I'm getting shocked more frequently too when I touch my car. Could this be a grounding problem?
Any help would be greatly appreciated!
