This is a very good intro 12 inch sub. It hits very well with a 5 channel amp, 250 to the sup. Not sure of the alpine model but it is a recent d rated amp and very efficient. If you need more, you are deaf and it won't really matter what you listen to.

I have 2 of these sws 1243 d. in my grand Prix. They are in a ported box with 1.5 cu ft powered by a Kenwood kac performance series amp. I tested it with the meter and am getting 255 watts to each sub. I have a new Alpine head unit powering the amp and the subs. I wired the subs to 2 ohm's and I was seriously suprised of the amount of bass Im getting out of these alpines. I previously had 2 jLw3 subs wich are great powered by a rockford fosgate p 500 and the alpine kenwood setup is about the same bass. The alpines are hitting hard enough to hear from 4 blocks away. That is a true statement we have tested it. Anywaty I didnt expect to buy the alpine subs or the kenwood amp. I heard a system in a car with the same system and it hit incredibly hard for what it was. check out the Kenwood amps also much better than I expected. Never a drop in power and do not heat up because of the dual cooling fans. anyway great subs for the money.

I bought this sub to replace a 10" blaupunkt that blew. I bought only 1 and a planet audio AC1200.2 amp. at first I had it wired at 8ohm then the other day i wired it to 2 ohm. either way it has pretty loud bass compared to what i had, minus the fact that i just has a 200x system before. this rattles the windows on my house. although it doesnt get the deep notes in some rap i listen to its perfect for all the metal. GREAT investment for the money I plan on buying another one soon.
