I want to add a JL Cleansweep to an 08 Suburban w/Bose and Navigation. I'm adding new door speakers (front comps and rear co-ax's) and 2 10's in the cargo area. I'll have 2 different amps driving the speakers/subs. My question is do I tap the speaker wires to feed the Cleansweep BEFORE the Bose amp, or AFTER the Bose amp. I have a local guy telling me I need to tap after the amp, but it seems to make more sense to me that I would want to tap before the amp? Any help is appreciated.
