CleanSierra Posted September 7, 2012 Report Share Posted September 7, 2012 You WELDED your ground? How would you think that would have helped?!?! If anything that's the opposite of what you wanted to do. Moving your ground to find a better spot would've been the better approach. What brand RCAs are you using? Where is your power wire in correlation to the RCAs. What kind of deck are you running? What vehicle is it? Where is you front battery grounded to? Where is the secondary battery grounded to? Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...

Skullz Posted September 7, 2012 Report Share Posted September 7, 2012 Don't weld grounds. first thing to do is remove the rca's from all the amps and power them up and see if you get any noise out of your sub or stage speakers. The point is to try and isolate where the noise is coming from. If no noise is present then hook your stage amp up and see if any noise is present when you power it back up. If no noise then hook up the sub amp and see if you get noise when you power it back up. If your getting noise from anything then try another rca jack not mounted in the car ran from the h/u to the amp making the noise and see if it is still there. If you keep getting noise then try replacing that amp and see if goes or stays. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
ALPINE408 Posted September 7, 2012 Report Share Posted September 7, 2012 whats wrong with welding a bolt to the frame and then using that as a ground i have done it many times rca's running along power wire or over an ecu can cause this http://www.google.com/products/catalog?q=ground+loop+isolator&hl=en&prmd=imvns&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.&biw=1572&bih=750&wrapid=tlif134705969071310&um=1&ie=UTF-8&tbm=shop&cid=11587398529593101263&sa=X&ei=939KUOahJ8K0yAGd7IGABQ&ved=0CIcBEPMCMAY these have done wonders for me in the past and there cheap Have you ever had your woofers blown?

Chris Hammer Posted September 7, 2012 Report Share Posted September 7, 2012 Pics of said ground??? I wanna see how you welded it. Follow skullz instructions. It helps if you have an rca adapter for an ipod or another source you can send a signal to your amps with.

You wouldn't have welded a ground in a effort to get rid of that Nasty ground loop, would you have? I was referring to this not being a solution for a ground loop issue, which sounds to me like the OP has a case of. Im not the one you want to try to troll. Just a fyi for you.
