Amp new one year ago but just opened about a month ago when subs were built; mint in every way.
Trade MY 1000WRMS @ 4-Ohm desktop-rackmount amp/active LP xo/parametric EQ/continuously variable phase control for YOUR two or three reliable, reputable plate sub amps w/ active LP xo only (need to power multiple subs). My amp's parametric EQ may help flatten room modes or lower the bass cutoff frequency.
Negotiate value difference in cash if necessary.
Cheers!
