i have asked this question before but the amp has changed so i need help again. i have three pioneer 12's model# ts-w305c. they are 800 watts max 400 watts nominal with a 2 ohm rating. they are single voice coil as well. the amp i was going to use before was a bd 500 but it didn't come through so i am looking at the punch 401s. it is 1200 watts peak at 4ohms, 400rms x 1 at 4ohms, 200 rms x 2 at 2ohms, and 100 x 2 at 4 ohms. will this amp supply enough power to my subs to have them hitting hard. and how can i wire the subs so that i can possibly get all 1200 watts out of this amp or at least close to it?

Using three 2-ohm SVC subs will require you to wire them in series for a total 6-ohm load on that amp.  If you wire them in parallel, it results in a total 0.66 ohm load, and that is way too low for any of the amps you are considering.  At 6 ohms, the Punch 410S you are looking at will put out about 300 watts RMS bridged.  You will not get anywhere near the full capability of those subs using an amp like that, but it will certainly work if you set it up properly.  By the way, no matter what you do, you will NEVER get 1200 watts out of that amp, sorry.

tee17, to run three 2-ohm subs you need an amp that is stable at 0.5 ohm mono.  MA Audio makes a couple that might be in your price range.  Most 0.5 ohm mono amps are very pricey competition level amps, though.  Are you stuck on using three drivers?  You'll find it much easier to deal with matching an amp to two or four than three.  And if you decide to make a change, maybe I can talk you out of running Pioneers...

How many voice coils do these subs have, one or two?
