MTX took the volume that they had to work with , and tried to make the best accoustic box they could, i think. you can't really shake a penny off the car next to you or trigger car alarms with this box. if you are in house, you might hear me go by, but it doesn't really hit that hard. i don't care really, as long as it sounds good to me in the cab. also, i think it would help if i installed Dynamat. anyone have this? does it help? my cab vibrates too much

In doing so, you sacrifice low frequency extension. There were so many times when I could not hit lower then 35 or so Hz. And that is with (2) 10" subs.

I would have rather settled for a single ported 10" or 12" enclosure.
