I posted this over on the RL forum, hopefully I can get more info here. On my '04 RL w/ Bose and Nav, I was wondering does the deck output a level signal w/ no EQ or crossing? If I tapped this before the amp is it a full range signal? I was hoping I wouldn't need a sophisticated summing piece like a Rockford 3Sixty or JL Cleansweep. I would like to keep us simple with a 4 channel LOC. I also understand that by bypassing the bose amp I will lose my nav prompts and bluetooth, is this true? If you have any info please let me know!
