I used to run nothing but Cerwin Vega subs.
I have had probably 15-20 Vega model subs.
And switched to MTX.
I now run nothing but MTX8000's
They dont blow as much as vegas, are sound alot better for my use.
But, for hard knock deap as hell bass, nothing beats 2 12" vegas in a death box. (drools) I dont like having an extra 300 lbs in my trunk though. hehe.
