I'm looking into buying the Precision Power PPI P900.4.. It's got 2 different rating.. which one do i match with the speakers? Thanks for the help.

RMS Power Rating (14.4V):
4 ohms: 145 watts x 4 chan.
2 ohms: 225 watts x 4 chan.
Bridged, 4 ohms: 450 watts x 2 chan.
RMS Power Rating (12V):
4 ohms: 100 watts x 4 chan.
2 ohms: 150 watts x 4 chan.
Bridged, 4 ohms: 300 watts x 2 chan.

14.4V is when car is running
12V when it's not

Conservatively, go by the 12V since you know you'll always be getting that power.

I miss my p900.4, wish I didn't sell it. Oh well, still have one more. It really depends on how you plan on listening to your system. Hopefully when the car is on more often than not
