Is the amp available in the store? It's perfect for my application but it has no image and the description saying that it's essentially in a prototype stage.

It is not yet available.

Another question:

 

I have the SA 6.5 components and it says they are 60 rms a side. So 30 to the tweet and 30 to the mid per side?

 

I got a great deal on a RF T800-4 and it does 300 x 4 @ 1 ohm and 150 x 4 @ 4 ohm. Either way the amp's overkill, but it seems like my gain is going to have to be extremely low even at 4 ohms to keep from damaging the speakers.
