punch he's are rated at 200rms and 400 max. single voice coil with 2" diameter voice coil. I had a single 15" punch he in my fiancee's car running off 300 watts rms and it did fine and performed well.
if you have either svc 8 ohm or dvc 4 ohm you are going to get a 2.67 ohm load, my mtx81000d would do them quite nicely. supposed to do like 1300-1500w @ 2 ohm so a tad less @ 2.6... boom like so.
