Hey guys and gals! After searching here and google, I still haven't found the answers to my questions. Forgive me if the questions I ask have already been answered. I have a 2016 JKU Sport with the stock 130 head unit and no sub. It's awful. I am on a wife imposed budget (probably for the better) and I'm pretty well set on the Kicker speaker upgrade as they are plug an play and cheap. My question is, with retaining the factory 130 head unit(for now), are there any cheap(ish) sub-woofer/amp setups that I can add (via harnesses/adapters) without cutting factory wires that will work? I am not looking to have the best system in the world, just decent sound and decent bass.
