Too much power is your cap is getting warm... SA's don't handle 1300 watts IMO, I'd tone it down a bit, but that could be me. I ran an SA as well on 1000 watts and it ran fine. Could depend on box size etc.

The 1.3K's and all of the Twisted amps are a bit underrated. I want to say the 1.3k will do 1600ish watts rms @ 1ohm.

SA's can take some serious power for being only a 2.5 inch coil, but typically as you go up in power and push them far beyond their rated rms you need to start shrinking box volume (as with any woofer).
You can throw gobs of power at it in a box that is ideal to what they ask for, but prolonged periods of time your just going to be asking for issue.

I had a pair of the old rev 1 SA 12s in a 4th order bandpass powered by a SAZ-4500 and they took it fine for the longest time until one day they had enough and the surrounds tore, coils where still good though.

Granted even though the power is clean there will be a point that too much power is just too much, and an quality 3 inch coil is by far more forgiving than a 2.5 inch coil.

thank you! little delayed on the reply...i know it's throwing 1.5k consistently at the subwoofer, I toned the gain down and kept certain songs out of my daily tunes. Haven't had an issue since
