thehoe92 Posted October 29, 2009 Report Share Posted October 29, 2009 So I have had some faint engine noise in my system ever since I put my EQ in and its just enough to where I tried fixing it yesterday. Pull off my entire dash and find some threads on the side of my head unit so I get a bolt to fit in with some washers and run some 16 gauge from the head unit to a bolt right by my a-pillar where other accesories in my car are grounded and bolt it down. Put everything back together and start up my car and the engine noise is way worse now. I also noticed that when I turn on my heater/ac the engine noise gets worse as I crank it from 1 to 5. Isn't the point of grounding the head unit to ground the outer shell of the RCA which is the most common source of noise? What should I do?

OrionStang Posted October 29, 2009 Report Share Posted October 29, 2009 (edited) Try grounding it seperate from the other accessory wires you attached it to. Might help. Also recheck to see that your RCAs aren't around other wiring causing the interference.

thehoe92 Posted October 29, 2009 Author Report Share Posted October 29, 2009 I'll try that but wouldn't it not make a difference? A ground is ground right? Its the first time I've done something like this Quote Wouldnt be thehoe92 without teh purple Link to comment Share on other sites More sharing options...
OrionStang Posted October 29, 2009 Report Share Posted October 29, 2009 I always ground everything seperately (may be an OCD thing), can't guarantee it will fix it, but it won't hurt to try it. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...

Its the first time I've done something like this Also make sure none of your wires are running over or around your pcm(computer) or ac/heat module and the noise might be coming from interference caused by your ac/heat module or pcm.

X2... Didn't think about that. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
Kprice89 Posted October 29, 2009 Report Share Posted October 29, 2009 X2... Didn't think about that. At our tech school here in linn we always have people come in with similar complaints becuase they ran wires right next to the computer. lol.

thehoe92 Posted October 29, 2009 Author Report Share Posted October 29, 2009 right now its all off stock wire but I never used to have noise before the EQ. Quote Wouldnt be thehoe92 without teh purple Link to comment Share on other sites More sharing options...
HaMSaMMiCH Posted October 29, 2009 Report Share Posted October 29, 2009 I've seen shared ground paths between car audio and other vehicle accessories cause noise many many times. Try grounding everything to bare sheet metal about 8-12 inches away from anything else. Quote CAUTION! POOR INSTALLATION MAY SHORT BOTH YOUR SYSTEM AND WALLET Link to comment Share on other sites More sharing options...
Kprice89 Posted October 29, 2009 Report Share Posted October 29, 2009 right now its all off stock wire but I never used to have noise before the EQ. Maybe it is messed up?? I'm kinda puzzled now/ :01nocomment8so: Quote That could get interested with her potential positions, this being one of the better..
