Installed a MTX Stealth sub with a MTX Pro150x2 using the speaker level inputs and the sub inputs from the Bose system. Rocks hard when playing a CD, but getting a bunch of static when playing the radio. Any ideas? I figure its a ground issue, but am looking for any suggestions. I grounded it at the right hand side rear lap belt bolt, after grinding away the paint there. Tried using one of the existing holes in the sheet metal by the spare tire, still there.

 

A different ground and not using the pink wire for the amp turn on fixed it. The pink wire only had 9.8v on it by the time it was at my amp, so I had to run a wire from the fuse box to turn it on. It JAMS now.
