Subs and Amp - quick question

Hey there, I'm looking to buy 2 Rockford Fosgate P212s4 subs and a Sony XM-2200 GTX amp. Is that amp enough power to run the subs to their potential and decent sound? Have any of you ever had any experience with either of the two? And if not what other 2 channel amp (s) you guys recomend? Thank you

a friend ran a sony amp in a tempo and the install wasnt great. which cant say alot for the sony amp itself. but it really wasnt loud at all, it was a tollerable sound if anything when he had it 'cranked'... now that line of sony amp seems a little higher up on their list of amps, than my friend had, so you may have better luck, but i'd definitely look around for amps of the same price before buying a sony.

Forget the amp..I don't care how far up the line it is in Sony products..It's still sony..known to fail..known to disapoint..There are so many products out there that are better in the same price range..shop around on ebay.Dave

It's Loud

Yes I agree. I ditched the sony amp and bought a Rockford Fosgate P5002 Amp to pwoer the P2 subs.I think that will be a better choice.

Anyways these are the specs on the Sub and Amp as posted on www.crutchfield.com Amp: RF P5002 Key Features:         »      125 watts RMS x 2 at 4 ohms         »      250 watts RMS x 2 at 2 ohms         »      500 watts RMS in bridged mode at 4 ohms         »      stereo or bridged mono output         »      4-ohm stable in bridged mode         »      CEA compliant         »      MOSFET power supplies and outputs Sub: RF P212S4 Key Features:     * molded polypropylene woofer cone     * 60-ounce magnet     * frequency response 20-200 Hz     * power range 50-200 watts RMS     * peak power handling 400 watts     * sensitivity 86 dB     * 4-ohm impedance     * top-mount depth 5-13/16" (without removable magnet cover. With cover, depth is 6-1/8")     * sealed box volume 0.85 cubic feet     * ported box volume 1.75 cubic feet Anyrecomendations on an enclosure and should i use a capacitor?

That looks like a good match. If you are going for sq go with a sealed box. As for the cap you probably don't need one. Try the setup without it first than if you think you need one you can always get it later.

Well you shouldn't need a cap for 500W. And for the box well it all depends on what you like, most people say sealed for sound quality and ported for spl. Really you should see if you can listen to the subs in a ported and sealed box, and see which sounds better to you. Also if your building the box yourself a sealed box is easyier to build.

Cool thanks for the help. I had one more question. I was looking between two RF p2 subwoofer models. One p212S4 and P212S8 the difference is that the first is 4ohms and the second is 8 ohms, which shuld i go with? Which one is better?
