Need help with a new sub, a couple of n00bish questions
I'm trying to figure out how to figure out what size amp i need for this woofer
Rockford Fosgate P1S415:
15" 4-ohm subwoofer
molded polypropylene woofer cone with poly-foam surround
17-gauge steel bend frame
power range: 50-200 watts RMS (400 watts peak power)
frequency response: 24-250 Hz
sensitivity: 87 dB
top-mount depth: 6-5/16"
Polk Audio MM1240D:
power range: 100-360 watts RMS (180 watts RMS per coil)
peak power handling: 720 watts
frequency response: 27-200 Hz
sensitivity: 88 dB
top-mount depth: 4-5/8"
sealed box volume: 0.88 cubic feet
im planning on making a ported enclosure
for this kinda driver i only need a 250watt amp?
I bought both $50 each in box so no complaints also im using one for my car but that takes back seat for the one for the home theater
the wall with the tv to the kitchen is about 30 feet
Thanks a bunch from a confused little friend

Power isn't critical; there's a lot of leeway for a home theater application because the bass is usually intermittent. Not a like a car or party situation where it may be pounding at full volume for extended periods.
200 watts seems like a nice amount to aim for. Don't overlook used "pro" amps; they generally give you more watts per buck than a plate amp. Keep your eyes open at thrift stores, pawn shops and yard sales, if you can be patient. Or watch eBay for auctions near you; shipping costs may deter people from bidding.
