Yes, go to the HD amp channels connected to the underseat woofers and set the gain on those two channels to mid point. The midbass is there, but the MS-8 output is absurdly low to those channels...

The amps and processor are grounded to the factory battery ground in the trunk using 0/1 ga wire. It then travels to a distribution block where I go 4 ga to the amps and 8 ga to the processor. Are you suggesting that I connect the ground distribution block to the factory amplifier ground on the driver's side of the car? I guess I can throw a 4ga wire between the two and see what happens.
Yes, eliminate as many ground cables and junctions as possible.

Having that stealthbox means the whole thing has to come out though - bummer.
Test first and then install... shit happens.
