Loud little monsters

The following review is for THUNDER68, which is a part of the bundle you are viewing.

Like any of the MTX thunder line, these speakers are great! Piping around 100 watts to them and they scream. Decent mid bass and crisp highs.

Helps

The following review is for CVM, which is a part of the bundle you are viewing.

Installed on the trunk lid, was easy to place down stuck well and defiantly made the trunk heavier and stiffer. Didnt have quite enough to do all that i wanted but helped with rattle some what.

Great product

The following review is for CVM, which is a part of the bundle you are viewing.

Works great, bought a few of these and installed in my car in the doors and top to bottom in the trunk where my single 12" sub is. And what a difference it makes. My small system is much better sounding, and the increased bass response is incredible. Is it the best product of its kind, maybe not. But Is it totally worth the money, yes. I have used the much more expensive dynamat in a previous vehicle and this stuff is just as good, not to mention it costs a lot less.
