tell you what,i'm thinkin' of doin' nothing to the box after this past weekend.i used my 100 wpc technics receiver with my teac eq to power each sub and this thing POUNDS like never before totally,totally killer.i'm sitting on the floor ckecking it out and from 8 FEET away how i describe the gusts of air from the ports?i need to get some real power behind this thing,i knew about parts express(they will not get a monitor amp back in there)so i'll check this other site in a minute.i had 16 hours over 2 days to beat the hell out of this thing to see if a driver caused the amp to fry so i think these drivers are good to go and it's functional till:
1.i fry the receiver.
2.i justify the cost of an amp
