newbie! please help

My HU is an Alpine 9807 that has 3 pre amp outs. I also have a momo MM12 that I bought from a co-worker that was down and out. My question to you experts is can I use a Kenwood Excelon 5 Channel Amplifier KAC-X650D to push the MM12 or is it to small? Question #2 is what does it mean by 2 or 4 ohms. Don’t ohms measure resistance? Question #3 it says 12 V or 14.4 V I assume it means volts; but I only have a 12 volt battery in my car. I guess you can see I an new at this stuff but an willing to listen and learn. Thanks in advance.

These are the stats of the amp:

Bridged Power Output at 12V: 60 Watts x 2 (1kHz, 0.5%THD) 200 Watts x 1 (100Hz, 0.5ïD)
- Bridged Power Output at 14.4V: 80 Watts x 2 (1kHz, 0.05% THD) 300 Watts x 1 (100Hz, 0.5ò0THD)
- Maximum Output Power: 160 Watts x 4 + 600 Watts x 1
- Power Output at 2 Ohms, at 12V: 60 Watts x 4 (1kHz, 0.5% THD) + 200 Watts x 1 (100Hz, 0.5%THD)
- Power Output at 2 Ohms, at 14.4V: 80 Watts x 4 (1kHz, 0.5%THD) + 300 Watts x 1 (100Hz, 0.5%THD)
- Power Output at 4 Ohms, at 12V: 40 Watts x 4 (20Hz - 20kHz, 0.05%THD) + 150 Watts x 1 (100Hz, 0.5%THD)
- Power Output at 4 Ohms, at 14.4V: 60 Watts x 4 (20Hz - 20kHz, 0.05ò0THD) + 200 Watts x 1 (100Hz, 0.5%THD)

im sorry to say that amp is too small:(
it puts out only 200 watts RMS where the mm12 needs as close to 500 as you can get

and those 200 are at 0.5% THD, which is pretty high, comparatively... but im confused: the bridged power is listed at (14.4V) 300 W for the sub channel, but the 4-ohm output (also 14.4V) is listed as 200

in any case, that thing's not quite strong enough :(

Since the first question has been answered....

#2 You're right about Ohms meaning electrical resistance. To answer it quickly...The fewer ohms, the less resistance. If its resisting less, more power can be produced.. Kinda like 2awg wire can have more power flowing through than 4awg wire can...less resistance so to speak.

#3 Most amps are rated to 14.4volts because its theoretically the max number of volts that a car alternator can put out, assuming nothing else is drawing from it. It's just to put a larger wattage number on the box without really lying about it. Under most cases, your car's electrical system will only be capable of providing the amp around 12volts. If the watts @ 12 volts are available, you should use those numbers to match with the speakers you plan on running off the amp.
