You cannot bridge a 2:50, they are independent power amplifiers in a single chassis. But you can run a preamplifier for a bass through them and into bass cabinets with absolutely zero problem.
The Mesa Powerhouse 2x10 cabinet will pair up with that quite nicely; though the Carbine does put out more power than that cabinet can handle if you happen to really push it (you wont have to)
I run my M9 Carbine with a 4x10 powerhouse cab and a 1x15 powerhouse cab. when I don't feel like...
Apologies, I just read the rules here and I do NOT have 10 posts before I made this post. I will go talk some more in the other forums, but I AM very much on the hunt for a DC-10.
