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 agree with every one above. OFC is much better. Copper is a much better conductor than aluminum.
