osamio Posted January 29, 2011 Report Share Posted January 29, 2011 Yeah that ground is JUNK! Ground to the strut tower or somewhere near it. Can't be on something that is thin as a fingernail. x2! That is a thin POS ground, and that part is probably not a part of the chassis of the car, it's probably spot welded and glued on... Look for a bolt that you KNOW is going into the frame, strut tower would be great. OR find a spot on the main body of the car, if your car is newer it will be a unibody car, so any LARGE, key word LARGE metal area is fine, like the bottom of the trunk, or even the floor of the passenger area, like under a seat. Sand off the paint just like u did, and bolt it on. You will see a NOTICEABLE improvement with the headlights dimming etc... if u fix the ground. it might even fix the problem 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

But does it do it as bad? Did you also grind the paint away around the area on the shock tower before you grounded it there? Rest In Peace mother.
