The subs are rated at 400 watts RMS and 800 peak, so a JBL BP1200 would be a better fit than the BP600. Also, depending on which ohm subs you have (hopefully the 4 ohm ones), you could look into a Rockford BD1000 which maexes power at 2 ohms. If you have 8 ohm subs, then you'll need something that maxes power at 4 ohms bridged, like a PPI PC2600, RF Punch 800, Phoenix Gold ZX600ti, etc....

SiClone is right, it depends on the subs you have and thier ohm load.
What is your budget for a new amp? |
