Bad ground at the amp

[flcb7]

I had the same prob. mine ended up being nad RCA terminals on my head unit. But yes it does sound like bad ground but you cant say its at the amp. Its a good place to start but it sound like the have a bad ground somewhere else. You are going to have fun trying to find your bad ground. Took me like 2 months to find out it was my 1year old head unit (pioneer)
Another rout you can TRY is. Go buy a "ground loop isolator" and try that. But I would try and find the bad ground be4 going to the option.
Good luck hope this helps a little.

did it just appear suddenly or is it just getting to you now?


It's possible that it may just be engine noise coming in from your power AND a bad ground causing interference. But check your grounds first.


Easiest thing to do it start at the sub. check all of the wires INSIDE the box to the sub, then the wires to the sub from the amp. and forward to the amp and on all the way to the HU. If you don't find something loose or looking fried, then i would try to make sure you have good RCA's. the cheapo ones can have bad insulation and that can cause engine noise.


If it's not the grounds and you have good RCA's then you might have to start checking everything with a multimeter to make sure nothing is ohming out.

Sounds like you pitched a RCA or something since it came out of nowhere. That happened to me I couldnt find what it was on my mold system I just got fed up w/ it and ripped the whole system out. While doing that I found I just pinched one of my RAC cables. I was sooo pissed!

I have the dreaded alternator whine coming from my 6's in the back. I bought the ground loop isolator the other day and hooked it to the rca's going to the amp that are powering the 6's but it didn't work, i ended up returning it. Sooo.. next i'm gonna reground my headunit (a pioneer) and amp to see if that fixes the problem.. does anyone use twisted pair rca's, and if you do how much did you pay, cuz the one's i saw are like $60 for just a couple of meters. I want to try to eliminate any problems.

You can try grounding your rca's to the radio's chassis

do you need some special rca cables with grounds or do i have to splice it in myself?

x2, i'd be interested in how to do this too. almost every stereo i've had has had some sort of buzzing, always quiet but i can hear it when the stereo is very low volume.

I have this same issue and I have to solve it since I am running all my speakers through a 4 channel amp.

hope this helps.
