OK guys, I'm making this so much harder for myself than it needs to be lol. I have a 13 Avalanche with bose. I'm looking to add this Kicker Hideaway powered sub to the truck. I've been searching for a good while trying to figure out what wires to tap and where. I've read that some tap the factory sub wires for signal, some have tapped preamp ect..... I'm drawing a complete blank and wanna do this correctly. I've done systems in the past, but nothing with factory head unit/bose/oem amped systems. Any help is appreciated
