47 ohm?

You can probably use a sub but the originals are readily available.

yeah sorry 47 ohm. I can get the 46's but have nothing in stock right now. And im trying to get a few of theese amps worked on to get them out the door since i have a million things going on right now.

Would the 44's be a good sub or wondering what might be a good sub?

The Z44s can't handle as much current.

What do you have in stock?
