Car audio in my house

I've got a 12"  Kicker SoloBaric L7(dual 4 ohm) in a slot ported box that i built, which is about 2.25 cu. ft.. Well, one day i bought new subs for my car, and no longer needed the kicker, so i came up with a great idea (in my opinion anyway). I opened up my powered subwoofer that i have sitting in my room and wired the kicker to that. Im assuming the 8" speaker that came with the powered sub is a 4 ohm sub which would mean the the amplifier supplies 100 watts @ 4 ohms. After wiring the kicker's vc's in parallel, i figured the amp was now producing about 200 watts rms. Then came the day that the amplifier decided it was time to die (oh well ). i guess i pushed it too hard.

It just so happens that i've got an Alpine MRP-M350 amplifier that i dont use.Yes, it works. The amp is capable of supplying 350 watts @ 2 ohms, 14.4 volts (the L7 can handle 750 rms). There are 2 20 amp fuses on this amp, for a total of 40 amps (duh!) i was wodering, if i bought a 40 amp power supply, and powered the amp with that, would that be sufficient to run the amp? Would i burn up the power supply by using it all the time, mostly for music, or are bench power supplies only for testing amps, and not for supplying power for continuous periods of time. Any help would be greatly appreciated.

Thanks for the insight krf01, and thanks for directing me to the adire website. I found some really interesting things there! Anyone ever hear of a motor structure that is capable of 12" peak to peak stroke? yes i said 12 inches of peak to peak stroke!!! Check this thing out at adireaudio.com. Its called the Parthenon. when you find it, read the whole article about this beast.

Again, thanks krf01!
