Installed my amp/subs today. Everything actually went very well. Tapped into the sub output wires and remote wire at the factory amp. Ran the power cable down the driver's side of the car, and the RCAs and remote wire down the passenger's side of the car. I grounded the amp to the body at a mount for the back portion of the back seat.

In any case, after the install I seem to have a reduced signal when listening to FM. I haven't tried AM yet. Most stations that came in very clear before, now come in poorly. Any idea why this may be? Is the antenna wire ran down the driver's side of the car and maybe my amp power wire is causing a problem? I can't see it being a problem with the harnesses on the factory amp as I don't think the antenna wire would run through there.

Also -- I have not fully secured the bottom of the back seat yet. I have put it back in, and secured the clips, but not the bolt next to the arm rest.

Any ideas?

 

Ok... After doing some research on the Audio forum it seems my Class D amp may be the problem. Anyone else run into this?
