I have a Massive Audio d1200 Class D Mono amp. Purchased new last year, only ran at 4 ohms.

250 watts @ 4ohms
450 watts @ 2 ohms
600 watts @ 1 ohm
LPF 40hz to 220hz
Subsonic off to 50hz







Want to trade for an IDQ 12 Dual 4 or JBL GTO1214d Dual 4 or other 12" dual 4 ohm sub that leans more towards SQ. Must be in good shape.
