Hi everyone! Get my soul I bought last night later today! So excited. It's a 2013 +. I've been reading a lot of the posts on aftermarket sub installs and it looks like a lot of people used the factory sub's hookup for running the line in's to the aftermarket amp. A question I have and couldn't find an answer for, is that ok to do? What I'm wondering is aren't those speaker wires getting fed already from one amp so is that going to mess up sound quality or possibly hurt my amp with those coming in as high level inputs, or does that matter that they're coming from an amp to another amp versus a headunit to amp? I'm no audio guru just know enough to be dangerous and want to do it right. Appreciate any help you all can give.
