I built this with myself in mind. I seriously doubt that you could find better quality anywhere else. Check out reviews on the sub. It top of the line, and according to all reviews it hits hard when cranked up. I've only tested it at low power because it's not broken in yet. The sub is a JL Audio 8w3v3-4.
Very nice job, I used to do stuff like this years ago but now I just want to go the easy route. I planed to do just that but the dealer messed up my order on my JKU and the Alpine system is no longer in my build. So now I need an alternative and was looking toward the Kicker system but the sub seems to go behind the seat and I want it to be part of the Jeep. Plus the cost is crazy for the sub but I like that it says plug in and go. Is there wiring hiding somewhere in the Jeep that is ready to go for a system? Could I just buy the Kicker speakers and say get that Infinity BassLink and tap into the factory wiring instead of running it all like days past?
