About the MTX ThunderForm Unloaded Enclosure
Crinkled french fries, discarded receipts, old gum wrappers you probably have everything in the hidden corners of your vehicle except great bass. ThunderForm enclosures fill the nooks and crannies of your vehicle with low tones that stand out, but their factory look blends right in.
MTX engineers evaluate the "sonic signatures" of top-selling vehicles so they can design ThunderForms as custom acoustic matches. Each ThunderForm fits and blends inconspicuously into your vehicle, so you get great bass without losing any space. They're made of high-density polyethylene resin to curb resonances they deliver bass that's tight, hard-hitting, and way down low. The airtight enclosure provides the correct internal volume to yield optimum bass response.
This black enclosure comes without a speaker you install your favorite 12" subwoofer. For best results, MTX strongly recommends using a speaker designed for an enclosure with a volume of 1.2 cubic feet. The enclosure mounts in the trunk on the passenger side of select 2005-2009 Ford Mustangs.

MTX ThunderForm Unloaded Enclosure reviews
This enclosure fits good; just make sure you fold the carpet under its self like the directions say to do. Used a AudioFrog 12' (G12D2) along with an JL Audio (JX500/1d) for power. It sounds good. If you don't want to break out the table saw and build something from scratch and want some bass this might just work for you.
Pros: Looks and Fits good.
Cons: Plastic enclosure.

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.
