TBSS07 Posted March 22, 2012 Report Share Posted March 22, 2012 (edited) Ok so i have been helping a friend put in his system in his 98 silverado and i have everything ran correctly (rca's away from power and ground cables etc..) and there is still this buzzing or humming noise through the speakers it doesnt affect the music because when you turn up the volume it isnt noticable but when there is nothing playing you can hear it. He is running 4 alpine type r components and the amp powering them a is a quart 4x125. I was thinking it could be a ground loop but im not positive.

412 CVX Posted March 22, 2012 Report Share Posted March 22, 2012 bad ground? sounds like a familiar problem, i just don't remember what exactly causes it..

My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

rocking.that.eclipse Posted March 22, 2012 Report Share Posted March 22, 2012 Is it from the alt? When you rev up the engine does the buzz change? Quote Link to comment Share on other sites More sharing options...
TBSS07 Posted March 22, 2012 Author Report Share Posted March 22, 2012 Is it from the alt? When you rev up the engine does the buzz change? yes it does change as the engine revs so it is the alternator then?

That's not really a good spot. Did they sand all the paint off the metal? Quote UBL | Build Log Link to comment Share on other sites More sharing options...

KOZ89 Posted March 22, 2012 Report Share Posted March 22, 2012 (edited) when you remove the carpeting from the existing bolt that it's sitting on, you will either have a rubber or plastic style bushing that is probably not making a good ground for the amp sitting around the bolt. Check grounds again, and use sand paper Edit : F.Y.I, my truck has a bushing for every bolt sticking out, so i needed to cut out a piece of the carpet, and make sure there was a clear grounding source Edited March 22, 2012 by KOZ89 Quote build coming late April, early May build log for 1 LVL 5 18" 87%ish done : http://www.stevemead...ab-dc-lvl-5-18/ 1997 Dodge Ram 1500 Slt Laramie Amplifier - AQ3500d.1 Sub - DC LVL 5 18" Highs - (2x) Selenium ST-350 Super Tweeters 8ohm Mids - Selenium 6" 200w midrange 6W4P (pair) Mids/Highs Amp - MB Quart ONX4.125 1000watt 4 ch Wiring - XP Flex 25' Red, 25' Black Alternator - Mechman 270amp Battery - XS power D3100, 1- Yellow top front more to come...
