nigga please, I will toast you both.  And first, we should involve Scott in this too, cause he has us all beat.
Kevin's got the two MTXs, nice subs, but hes got a Pyramid amp...sure its 1000watts, but those are pyramid watts, so its  more like a distorted 500.  Your on a JBL 12, also nice sub, but its very old and low end.  And you're only on a Jensen.....250?  I'm on two MTXs, old models, but in the craziest bandpass box in the world.  Pyramid 600 watt, which is like 250 real watts, but this box does NOT need more than that.  Unless I want to blow out my windows, haha.
Scott, however, is on one MTX 12, in a fucking sweet box, with a JBL amp (soooo god damn nice) and a capacitor.  Plus his Clarion deck, and infinity speakers all around with 100 watts a piece (they were like $100 a piece!)
But as far as you, me, and kevin....I have you beat.
