in the trunk where it belongs!
this is what i did its customThat is waaaay too steep for me!
x2.... love mine! They even offer a self-powered one if you don't want to mess with a separate amp.I got the MTX thunderform, and love it! Super light, hidden and best of all, fits a 12" sub:
Thunderform Series FMUST05 | Ford - Mustang 2005-2012 | MTX Audio
The thunderform I got was from ebay. It came with a sub and the box for under $300. The sub is decent, but I wanted a bit more so I got an RF P3 shallow mount DVC running at 1 Ohm.
The box color matches the carpet perfectly and fit a shallow mount dvc with a large magnet just fine. Sounds great too! I mounted my amp on the opposite side for equal weight balance since I hit up road courses.
Yeah, I believe the self powered one runs around $500.x2.... love mine! They even offer a self-powered one if you don't want to mess with a separate amp.
