so how much capacity do i need to do this if the amps are 320W RMS each?

IME plugging your amps into the BPT can cause a thinning of the sound. I had a BPT 2.5 Signature that I used with a number of amps, and always ended up running the amps directly into the wall because I was unhappy with their performance when plugged into the BPT. I replaced the BPT with a new Power Plant Premier and the transformation was wondrous; amps are plugged into the PPP with none of the problems with the BPT.

Maybe the "thinning" was due to less noise?? Put your hand on your woofers when nothing is playing to see if they are moving. If there is any motion felt, you have noise.
John...one of my custom BPT units or Chris unit? Our version never thin out the sound quality. The custom unit had a meaty kind of sound quality.

Hi.
If it was, say 700W (typical power rating for a 320RMS amp), so two amps will be 2x700W = 1,400W.
I would specify a minimum 5KVA (min 5 times the rated power supply for your amps) isolation BPT.
But don't hold you breath yet - not many powerline transformers do not
impair the sonics of your system. This is my bitter costly experience.

I tell people to expect 40% of the transformer max to be released as heat. To answer that question I would need to know your system specs and the model BPT unit.
