PopTartBandwagn posted a topic in Audio, Infotainment Navigation, MyGig, UConnect, etc.Hey everyone, I'm curious to know if anyone has installed an aftermarker AMP and sub on their Journey. I've installed an AMP, however my sub isnt producing the bass I'm looking for. I'm sure it has to be the RCA cables, so my question is where can i tap the RCA cables to? I currently have mine tapped to the rear speaker wires behind the head unit. is there anywhere else i can so that?
