There is a version with bluetooth, but it's not on sale, so quite a bit more expensive...

For bass frequencies, you are typically current limited, for treble frequencies you will be voltage limited.
If you must upgrade the power supply (it's a complete waste of money), but a 32v 10A is better choice than 53V xA, because it'll run cooler, and give you all the bass you can handle. Other members have tried the 45v supplies, the amp gets hot.
It's a waste of money, because it already gets super loud with the stock power supply.

I have a x3600h , and I am thinking you can use these amps to get the extra 2 channel via pre outs making it full 11 channel. I have a Sony STR Dh190 in a similar setup
