New Engine Noise!!

[Eggrolled211]

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.................

i got the same shit if i fix ill tell ya how

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!

I've been on it for hours and I got it down to a little bit of a whine bearable but still annoying since I know its there I'm very picky! Oh well life sucks...Atleast now my UUC twin silencer exhaust is covering it up.....a bit. I just didn't expect to have this sound in a BMW ....grrrrrrrhhhh. SubOptimal quality.............sighing......................T hanks for the help and advice "Jllphan"

[BUSTaMOVE]

Yeah i bought a new amp and it fixed my problems just went with a 4 channel instead of my five channel

[jllphan]

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.

[Eggrolled211]

Yeah...I think it could be my AMP? who knows....I thought ADS are good amps?....I'mma try getting more better expensive RCAs?....then ground loops isolators etc. If all fails .... the AMP goes!!!! agggghhh...Dammit what a waste of $160.00

[BUSTaMOVE]

make sure no speaker wires from old stock amp or anyhting else is grounding out ( touching your body) i mean anything i fixed my problem

[Eggrolled211]

Okay...I have phoenix gold and rockford fosgate RCAs etc. Those aren't cheap...therefore can't be the problem..I got rid of the kmart brand lol.... I'm using 4guage power and ground source....last thing is the ground loop isolators...but thats $50.00 ................I'll check the speaker wires again....thanks.

Do you have anything (stereo, speakers, etc.) still attached to the factory amp?

[Eggrolled211]

the stock amp powersource etc. is diconnected. all the speaker outputs from stock amp is being run by the new 6channel ADS amp(I cutted them etc.)....I think I might just have tooooo much electronics in my car. Navi/PS2/Monitor are connected but not on or used.(disconnected from powersource when not in use.......
