Hi hippymailman, I'm heading down the same path as you did. I've already had someone put in an
Alpine ILX-W650, Rockford Fosgate amp and
speakers, and had the console
speakers disconnected. I'm now looking to tackle the subwoofers. The main problem I'm trying to solve and so far have been unsuccessful is the 'pop' from the subs when you turn the car on, as I still have the original factory setup with the sub amp that is bolted on to the one sub. So unless if there is a quick solution to the 'pop' problem, I'm thinking about bypassing the subs. So I'm interested in understanding more about the sub that you had built that is behind the seats and how well that is working for you. I'm thinking about putting a powered sub unit on the rear deck that is typically used for under a car seat. My other option would be to bypass that factory sub amp and drive it from the Rockford Fosgate amp. Do you know how to get to the subwoofer area from the back by removing the 'curtain' such that I don't break anything and can hopefully easily reinstall it if I decide to head down this path? Thanks, I appreciate any insight you can provide!
