[QUOTE="zako, post: 7658752, member: 629735"] If you're worried about size, etc, get a PPI Phantom amplifier. PPI P900.4 provides honest power as rated for 4x140watts at 4ohms or 450watts in bridged mode. Sonicelectronix has the 4-channel version for $200 shipped right now minus a 10% discount if you enter the "PPI10" coupon code, if it hasn't expired yet. I bought mine for $230 and I thought it was worth that price. There is also a 1-channel PPI P1000.1 and 2-channel version PPI P600.2.
