So I ordered an aftermarket JL sub and amp to replace the factory one that came in my truck. I don't want to change the head unit etc, just the sub. So I pulled out the factory box today from under the seat and discovered a little silver amp that powers the factory sub. My question is this. I wanted to just run RCAs off of the factory sub wires and into my new amp etc. but now it looks like I will have to incorporate that little amp because it has a big harness going into it, and then two positive and two negative wires leaving it (the wires I will tap into for my new sub) does this all sound right? I can post pics if needed.
