I have a 2004 Wrangler TJ that i put an unloaded ThunderForm in with two of these subs and a THUNDER500 amplifier. I can't believe how loud these subs are. I listen to a lot of rock and country and I am amazed at the difference having a subwoofer has made in how much of the music I actually here now, its like hearing some songs for the first time. Great subs, great box, and great amp, thanks MTX!
I've owned a lot of different subs, I put these in an MTX bass slammer box for a 2003 chevy silverado extended cab, and they are by far the best sounding hardest hitting subs I have ever had, I was skeptical at first being the shallow mount, but they are better than any regular subs I have ever owned !! Great job, I would recommend these to anyone and everyone thinking about adding subs to their vehicle... Super happy!!!
