shepherd92683 Posted April 27, 2014 Report Posted April 27, 2014 I changed my rear battery and amp grounds from the seat belt bolt (yes I can't believe I did that in the first place) to grounding my battery to the frame and my 2 amps to my rear battery. Now I have much more stable voltage and an incredible ground loop! The noise happens when I apply the brake of shift gears and it is very loud. I tried to ground the rcas on both amps to different locations and no luck. Can someone give me an idea where to start or what to do to fix this, thanks!! 2017 Honda Accord Touring Build coming soon
shepherd92683 Posted April 27, 2014 Author Report Posted April 27, 2014 After removing the mid/hi amp ground, problem was gone. I put a new ring terminal on it, reconnected it but nothing changed. Seems to be in that circuit somewhere. What else to check? 2017 Honda Accord Touring Build coming soon
rockFord_Expedition Posted April 27, 2014 Report Posted April 27, 2014 Are both of your amps grounded to same place? Have you: - grounded alt case to frame - front battery to frame - add hu ground to chassis - chassis to frame ground All grounds 1/0 or bigger except hu of course.

jdshott Posted April 27, 2014 Report Posted April 27, 2014 Ground it somewhere else and use sandpaper or steel brush .... that's first thought how close is your battery to amp ? how are your rca's ran ? if they cross any power it must be a 90 degrees or 18" from higher power . is your battery grounded with correct size wire ? No 1 But me paid for this stuff and NO FREEBIES so no brand names (No Free Advertisement ) A SQ head unit 6 5.25 2 X 6x9s 7804 P400.4 4001D 1 34s (Maybe time to change brand) 4 X 15" s !/0 @ 2/0 OFC Wiring :morepower1: :morepower1: ill say it like i always say it. F##K the DD-1. I don't care if you or anyone buys one. (well i do, but that isn't my point) Get an O-scope in the very minimum and learn how to use it or you are just guessing your settings like every other noob. once you master the O-scope then step up to a DD-1 or even better a DD-1 Plus.
