I've pretty much decided that i'm gonna go with a pair of rockford p3 sd ten's for my dodge quad cab. How powerful of an amp do i need. Each sub puts out about 180 rms, 300 watt peak. So would i need around 400 watt rms ? What else should i look for. The amp will only run the two subs. Also what is the difference between two ohm versus 4 ohm in subs ? Thanks

P300-1 Rockford Fosgate (150 x 2 or 300x1) Class D mono block amp is a perfect match for those punch subs. 4 ohms and 2 ohms are resistance levels. The lower the better. (also the way you wire your subwoofers, if you have two subwoofers you would wire them in parallel (putting both positives together and negatives together would get you 2 ohms)).
