I have 4ohm vc's, so if I wire them correctly, I will have a 8ohm load from each sub. When wired together in parallel, that will give a 4ohm load at the amp, which is what it's stable at bridged. That should give 250watts to the subs, which will give them adequate power. Not the most they can handle, but they wont be "underpowered" there.

 

You said you had them wired to 2 ohms one to each channel which was 125 per sub correct?? If you do what you said above and wire them at 4 ohm bridged you are getting the exact same power at 250 watts to both of them which is 125 watts each. You wont gain a thing by doing this.

You need a bigger amp.

 

Get you a 750.1 and you'll be good. That'll be pleny of power for those subs.

 

I believe those are only 2 ohm stable....you could try one ohm but it will most likely run hot if it doesnt shut off.

 

Ok, thanks! I was told it would be 250watts to both subs since they were parallel. So it would still only be 125 to each?

 

Yes it would only be 125 each. You are getting 250 watts total out of the amp when it is bridged at 4 ohms. This means no matter how many subs you hook up to it the amp is still producing 250 watts total. Two subs equals 125 watts each, 4 subs equals 63ish watts each, etc.

If your wanting to stay kicker you will need something like this:

This will give you 425 watts per sub when hooking one sub up per channel at a 2 ohm load.

 

Or you could get a Memphis MC1.500 and wire them down to 1 ohm.

500W x 1 at 1 ohm which will give you your 250 to each sub.

BUT what you really need lol a lil over kill but

Memphis MC1.1100 and again wire them to 1 ohm and have 550 to each.

 

What kind of box are you running the subs in?? If it is sealed and at the recommended specs or a little smaller then you could probably get away with 500ish watts each. If they are in a ported box at recommended specs I would not run more than 350-400 watts to each. When you run a ported box your efficiency is much greater than in a sealed box and you really only need about 80% of the rms rating for each sub.
