Basically I'm looking for an amplifier for the SWS-1222D
Size 12 -inch
Impedance 2 ohms
Dual Voice Coil Yes
RMS Power Range (Watts) 50-300
Peak Power Handling (Watts) 900
Since its DVC 2ohms, Should i be looking for an amp that delivers power at 1 or 4ohms? Additionally, I've been told by many people that i should look out for a 2-channel amp, so when looking up the specs of various amps, should i be paying attention to the bridged power output at 4ohms in comparison with the subs' 300 RMS?
Can someone tell me what the main difference between a 2 and mono channel amp is? Anyways, i found the MTX Thunder 2-Channel Car Amplifier (TC3002). Will this work out?
Can you recommend me other amps that would work out too?
THanks :)

Most (95%) 2 channel amplifiers are class AB (65% efficient)
Mono amplifiers class D and are 80%+ efficient.
Mono amplifiers are also more likely to have low pass filters and subsonic filters.
You do have the choice of 1 or 4 ohms. 1 ohm is preferrable.
I would look for a good 1 ohm stable amp with a RMS power rating of 300-400 watts - no more - unless you are planning on adding another sub in the near future.

MTX Mono Car Amplifier (X1000D)
or?
Infinity 600 Watt Class D Subwoofer Amplifier (611A)
And i don't have any major intentions of adding another sub or anything else, so nothing much with long term-customization.
Thanks for your reply tho :D

It's a real trade-off here. You have 2 main choices as Kit points out:
1. A 2-Channel, Class A/B amp the is 4 ohm stable, bridged and less efficient
2. A Mono Class D amp that is 1 ohm stable
The "MTX TC3002" is adequate for this sub. The max current draw is ~37 amperes at full power. Not a bad option if you don't plan on going bigger later. (Most 2 channel amps are cheaper per watt these days)
This one lacks the SSF feature, so you have to go sealed for best results. (0.85 cf internal is just right for SQ installs)

The infinity amp is a little strong, but good bang for your buck.
With proper gain adjustments, it will work well at 4 ohms. It also allows some headroom for expansion even though there are no plans for that now.
