first off, everyone claiming the new amp, IT IS on the way. We did not show iut at CES due it it coming in late, a new van will be showsn, with a wall of Solo X's and the new am,ps at SBN in daytona.As far as the CVT, these were a HUGE hit. We have a demo Toyota with 10" woofers in the front doors. try that with any sub. They rock with the power, have great Xmax for a shallow sub, and 800 max power...what esle do you need for a door, or under the seat application. as far as the SXRC for the SX, that's two year old news.
