Ok guys and gals,

At a point and not sure what I can do. I have an 04 Accord sedan with the stock headunit. Running a JL Audio Cleansweep and the Memphis Big Belle amp. I have the newer Alpine Type-R 12 to run for the sub but I am not happy with the way the Cleansweep is setup.

A local shop did my install and have the rear/sub channel on the amp off the same signal input off the Cleansweep.

Guess my question is what is a possible way to go to separate the rear and sub channel pre amp?
