Where did you ground your amp ground wire to in your trunk???? I was told I needed to reground the amp.
I'm getting noise out of my subs. And when I turn the frequency up on the Amp you can really here it.

 

ground it under the back seat on one of the bolst thats on the chasis. that plate looking thing, make sure you sand off the area first!

 

i grounded mines to a screw behind the back seat but try your question in the audio forum. did you try using a noise filter on the rca plugs?

 

I did mine to the strut tower

 

i grounded mine on the bolt that holds the jack in place. the first bolt (i think 10mm) that you see when you open up that cover.

 

i drilled a hole thru the trunk and put a bolt thru the hole. it was on the right side of the trunk. if u pull back the carpet and look at the right side of the trunk there are two bolts already goin thru the trunk. i put the bolt thru right next to them and attached the ground wire to that.

 

I've been told by an installer that the bolts on the strut mount are bad for grounds.

Just drill a hole on the trunk floor anywhere, sand it, clean it, and use a nut/bolt combo and use that for a ground.

 

My amp is grounded in the spare tire well. Drilled a hole and grounded it there.

 

i havent had any problems with it
