Alright fellas, I just recently installed/rewired all the stock speakers/tweeters etc. onto my new 6 channel ADS amp...so far so good but I got this low wheazing/buzzing noise that gets louder as I excellerate! Very annoying ghead I check my GROUND its only 10-12"long...thats pretty short. I scrape the area around/near the ground area to make sure it has good contact. Still has that annoying buzz. Is there any option? I must get rid of it! I hate it! Grrrrrrrrrrrrrrhhhhhhhhhh! Any other ideas? Please.......... Thankz!

Hmmm okay I reasearch about GROUND LOOPS maybe since I have it connected to the common ground opposite side thus giving me...that grounding looping interference such and such. So I hook it up to only ONE common ground still that engine whine/noise....it wasn't making this whine with the stock Siemens amp......I dunno.....man I have all this top of the line shit....and it sounds like ASS!!!!!<---just the whining part.................

Well, you are at least correctly adressing the problem. Alternator whine is certainly a ground issue. A ground loop isolator is somewhat of a band-aid cure, i really wouldn't look into that as a fix (it does sometimes work, but usuallly just masks it somewhat).

What are you using as your ground? You might try a new ground location, or even the neg. term on bat.

Also where did you get your amp? Could be an internal ground issue. Try another amp if you have one laying around, or swap that one out if you can.

As for grounding,I have it place just behind the rear seats lower left side(my seats fold down) on the metal frame supporting backseats. I have my amps screwed onto the back of seats if I use the battery ground, that will be tooooo far? Shouldn't it be as short as possible? Can it be because I have multiple amps sharing grounds? I dunno. I will disassemble everything aaaaaggggain....look for another ground. I'm running the whole stock speaker system with an ADS 6ch amp...and one 12 eclipse sub via phoenix gold amp.....I have exactly NO whine comming from the subs at all....just from the MIDS and Tweets....aaahhhhhh everything sounds good except the whine...DAMMIT my car sounds ghetto man....aaaaaaaaahhhhhhhhh! Thanks for yallz help!

Yes, the ground should be as short as possible, but if your getting noise, the spot your using is obviously no good. You won't have that noise coming out of your sub (unless you are an idiot and don't the sub crossed over---lol) because your sub amp prevents such higher frequencies from reaching that speaker.

Bottom line man, there are a lot of variables with ground issues. I wish i could give you quick fix. That is what i attempted to do with an earlier post, but if that didn't work, you will just have to try a few different things (move ground, seperate ground for each amp, ground loop isolator, etc.) until you eliminate that FREAKIN, ANNOYING, HIDEOUS sound!

Yeah Busta, people will drive themselves insane trying to diagnose a ground issue only to find out later it is the amp!

If you ran new speaker wire it could be inducted from power cables... just a possbility.
You can run a ground wire as long as you want to, just be sure to use the proper gauge wire to handle the load, Still though, not reccomended. Try runing one to the battery post to see if that fixes it. If it does, there's your solution. I'd run 0 guage or thicker if I could, depending on how much juice your pulling.
