well i had read about it in one of the previews to all the products comming out in 2005, well, i was at a friends house yesterday and i saw pimp my ride and they put that 22inch MTX Jackhammer speaker into a car, it took 4 or 6 amps and 6 caps to power it and they said it went well over 10 decibals....i wanna kno has anyone heard of of these in person, that shit looked bad...
oh i forgot to add, it took like 3 batteries to power it
...if i had a truck or SUV....i would look into to gettign this personally
