Great fit - big sound and still have most of trunk!
Crutchfield Customer Review (What's this?)
This unit fits great in my 2014 Mustang GT. Love that I can get big bass and still get to the spare tire if I need to. I put in a Rockford Fosgate 12" P3 sub and it puts out some big bass. Note that the instructions say to screw the unit down through the floor of the trunk and then install the sub. I did not do this - I used some of the industrial velcro instead - so far, no movement. I may fasten it to the bolt that sits above it sometime later, not sure.
Pros: - As advertised, gives you a sub enclosure that fits your Stang without sacrificing the whole trunk. I can still lift up the spare tire cover and not brush against the sub - after I cut the carpet.
Cons: - It seemed kind of weird that the enclosure would not fit the MTX sub - at least the 500W one which was 1/8" too deep according to the specs. The Rockford Fosgate P3 fits just fine - but I had to screw the grille in separately as it would not fit into the inset. In the end, it all works and looks good though.
