who has any ideas on how to fix it? my amp ground is on the back wall. and my positive speaker connection i used spade terminals and my negative i did not. i bought ground loop isolaters they made my sound more clear but now i cant even adjust my amp and they didnt get rid of the whine. please i need suggestions ive been messing with it for so long and have gotten nowhere.

 

Make sure your power wires are away from your rca's...which means that they are run down different sides of the truck and never come close to each other. Also try to screw a piece of MDF to your back wall, then mount the amp on that... And one more thing to check is your ground wire is the same size or larger than your power wire and that you are using a good ground... paint scraped off to expose bare metal.

 

yep, i'm with proto

 

MDF? yes my power wire is on the other side of my truck, but the back wall simply just does not seem like a good ground. my - speaker terminals the wire is just tied to it could i not be getting a good ground on my speakers?

 

use a solder gun for all connections for one. If you amp has spade connections on it, get some spade's and solder the wire to the spade then plug it in.

second// use a jumper wire to quickly re-run your ground wire to your amps and see if that changes the noise at all. Use this method to try to isolate the source of your problem.

I bought a pioneer head unit and had major noise problems. I had to ground all the (-)'s on the rca's and I had to run a new power wire to the head unit from the battery.

I won't buy another pioneer.

 

Get your ground off the back wall, and run a search for proper grounding methods. Because you need to properly ground via DMM.

After that, then start on other things.

 

Just use a jumper like I said to make sure the ground is the problem.

Otherwise you will be go to a lot of trouble re-running wires that don't need to be.
