Alright I have two 12" 4-ohm SVC subs. I found an Amp that is a Class D mono amp, but it has two sets of speaker outputs? Is this so i can run both subs independently (wired like a 2-channel amp) and still present a 2-ohm load to the amplifier? Or do I need to wire it like a mono amp and wire the subs in parallel?

Also, would 12-gauge speaker wire be significant to power the subs?

What is the model number for the amp. MOST OF THE TIME THE PUT 2 SETS OF SPEAKERS OUTPUTS SO YOU DONT HAVE TO PUT SO MANY WIRES IN ONE SET. In side of the amp the 2 sets of outputs are on one bar but it just so you dont have 2 many wires on it. Ex you have 4 subs and you want to put them on to a mono amp. If there was only one set then you would have to put 4+ and 4- in one set but if there is 2 sets then you can put 2+ and 2- on one and the same on the other. Hope this helps. IMPORTANT NOTICE MAKE SURE YOU WIRE THE SUBS TO MATCH 2 OHM STABLE. AMP WILL OVERHEAT OR TURN OFF OR SUBS WILL BLOW UP. THANKS

"... OR SUBS WILL BLOW UP." Could you explain how this is possible?

12 AWG is fine. The outputs are parallel inside the amp.

Power Acoustic's ratings are very overrated almost laughable. Divide listed power ratings by 4. IMO, avoid Power Acoustic!

Really... thanks for the heads up. Not to get to far off topic, but Phoenix Gold Ryval V8001 was an other amp i was looking at. Would this be a better choice?

Sorry for the ignorance, but since the outputs are parallel inside the amp, does this mean that wiring each sub independently would still present a 2-ohm load to the amplifier? (in other words is that why the amp is wired like that, so i can run each sub independently/have more wiring options?)

Alright I have two 12" SVC 4-ohm 400watt RMS/1200 watt peak subs. They're in a ported box. And now Im trying to pick out an amp. I have $250 max to spend, and im looking for something with at least 600 watts at 2-ohm (more is obviously preferred).

Here's a few models I'm looking at...

Phoenix Gold Ryval

Crunch GP1500D

Kenwood KAC 9104D

Kole Audio KX1

I'm also looking at the Power Acoustik BAMF, Gothic and Power series amps.

As you can probably tell, I have no idea which amp I want/need. If anyone has any experience with the above amps(positive and negative) or any other amp that supplies a good amount of power for a reasonable price, please help.

Keep tucking away money for an amp.  $250 will buy you a $250 amp, whatever the name of the brand...it's still a $250 amp and will have the power of a $250 amp.  There are no miracles.

With a ported sub system, look for an amp that has a subsonic filter built in so you can set a protection filter at 25 or 30 or whatever freq you need.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

 Have you read the sticky "How to choose an amplifier" in the car audio section? If not,I think it would help you out .

IF your not  afraid of buying ebay. You can get a Kicker zx500.1. It 2 ohm stable bridged and they under rate there amps. My zx1000.1s put out 1280rms from the birth sheet. So the zx500.1 would be right about where your wanting power wise and off ebay and other places online you can get them for less than $250
