Help with aftermarket stuff

Hey what's up guys, I want to add a sub or two to my 2000 SLS with Bose, I know about the line level output converter and all that jazz, and am just wondering about some other things:

I'm 99 percent sure I'm getting either one 12" Memphis M3 sub or two 12" Memphis M3 subs. I can get a good deal on them, so price (on the subs) is not really an issue. My concern is picking the right amp and whatnot.
Each sub is 400 watts RMS, 800 watts peak, DVC two ohms. What type/size amp would be best for running this system?

Any help would be appreciated, please let me know about anything else you think I should know about this project

thanks guys

alright, thanks for the replies -
I'm also wondering - for anyone that "knows their subwoofers"... if you were looking for a good, reliable, well built sub that sounds good with all types of music, would you go for memphis m3's or mtx 5500's? I heard from someone that Memphis are "competition subs" and that they are designed to be louder than others, yet wear out faster than others. Any input on this?

so could you vouch for the practicality of getting two 12" m3s? Are they designed to be louder, yet wear out faster?

It's generally the same thing in catamaran sailing / racing - you can buy a $4,000 carbon / mylar laminate sail that will be dead in two years, but is the fastest design, or a $2,000 dacron sail that'll last for 10 years but isn't quite as fast.

That's the vibe I was getting when I talked to the dude I know that has one - they aren't the type of subs you want to be using everyday just for listening to music driving down the road, they are for the "once-in-a-while, blast your ass" type. But I don't know anything about subs which is why I came here.

Alright, I really need some help with picking an amplifier.

I purchased two Memphis M3 12" subs - each sub is 400 watts R.M.S., 800 watts peak, and is 2ohm DVC.

The thing that really has me confused is the power and impedance ratings - bridging and whatnot, and the dual voice coils, as well as amp channels, etc.

The amps I have been looking at:
MA Audio HK798, 800 watts, 2 channel - http://www.maaudio.com/product.jhtm?id=5&cid=12
MA Audio HK598, 800 watts, 4 channel - http://www.maaudio.com/product.jhtm?id=4&cid=12
Kicker KX800, 800 watts, 4 channel - http://www.hifisoundconnection.com/...fp/SFV/30046/vpid/3145924/vpcsid/0/rid/118099


Any help would be really appreciated, this is way too hard to figure out.
