I have an Alpine MRP-M650 amplifier and i need get subwoofers. What should i buy?

Answer 1

Since that amplifier is rated for 600 watts RMS at 2 ohms, then if you want two subwoofers you should pick either 4-ohm single voice coil subs or 2-ohm dual voice coil subs. Each sub should be rated for close to 300 watts RMS, which eliminates many single voice coil designs.

If you want to stick with Alpine, you can get Type R or Type S subs with 2-ohm dual voice coils:

If you're careful, you could use that amp with two Alpine Type E subs, though they're not rated for quite as much power as the amp can deliver.

Answer 2

alumapro are the kickin subs!!! i have an alumapro m-16 in my blazer. that is clearly more than your amp can handle but alumapro 12's will hit VERY nice with that kinda power. plut you really can't get a cleaner sub these days. check all car audio rev and you will see. they blow kicker,infinity and everything else out of the water. hope this helps.

Try ebay, sometimes you can get great deals there. Also, try spelling the item you want wrong, sometimes you can get a great deal that way.
