Price: $69.50 Pros: Fits perfect under passenger seat inside the tool box area. Discrete, secure. Cons: Road noise at speed makes it near impossible to hear Recommended? Yes
Comments: Installed two Kicker 4" x 6" dash speakers. Removing the originals was a major pain and time consuming but worth the effort. Further installed two weatherproof box speakers under the rear seat, also sourced on eBay. Coupled with the sub-woofer discretely hidden beneath the passenger seat and inside the tool box area, I can even leave the lid closed and feel the low end. Driving over 45 mph with my mud terrains still makes it near impossible to hear anything though.
Price: $110.00 Pros: Adequate Lows, Remote Adjustment, Tunable, Fit Under Seat with modification Cons: Took some effort to install.
I damaged the exterior of the case on seat bracket bolts. Recommended? Yes
Comments: Won't wake up your neighbors but will add some nice tunable lows to your system.
I Managed to squeeze it under the seat with some serious effort. (Seat removal and two washers required for installation)
