I've been reseaching about why subs hum, and I've tried pretty much everything I've read, except things like LOC and Ground-loop isolator. I traded someone in my family cash for an audio system out of a Ford Ranger.(Maybe it was damaged or dropped is the problem???) I put it in my 98 Sable, so it sounded okay at first, but I got a better and vented box for the 10 inch kickers. Now I can hear a very loud buzz/hum. At first I had all the same wires running next to each other, so I moved the RCA to the other side of the car...it kind of helped, but not too much. I can hear it beat, while it's humming, if I push the trunk lock, and I've even noticed when I stop, then take off, it gets a bit louder then levels off...This is only really noticeable with no music playing. When the radio is off or the deck is loading is when it hums so loud you can feel it in your chest. Now if I go and just look or feel the subs while music is playing I can feel and see it beating not to music, but to a constant interferance tempo....Everything I've looked at tells me GROUND problems, but I've checked them again and again. The amp is grounded under the rear seat, and the deck plugs into a harness, which the ground comes out to the truck screwed down. I used wire nuts to secure the wires on the back of the deck. If I unplug one of the RCA from either side the humming cuts almost to none, but if I unplug 2 from one side, it hums really loud again. I'm no pro at this, and I'm thinking I'm overlooking something, or could it be damaged amp or deck? Since this car has me used a harness I had the amp remote, deck remote connected to harness ignition.
I'm also ASSUMING this worked in the Ranger without a hum, I didn't it hear, but could see it with the small boxes (I saw it hitting with not music playing in MY car), but now with the "Polk Audio" box....well the hum.
Here is what I'm using-
new sosche wiring kit (remote, power, ground, RCA all for amp)
new sosche 98 sable kit ( 98 conversion harness, NOS faceplate,antenna,)
used Proformance Teknique DVD deck
used Power Acustic amp
used 10 inch 2X kickers (not sure what OHM or anything)
I really want this solved, if you need pictures I'll take them.
Thanks, Aaron
