do any of you run a 2x10 cabinet alone, without any other cabs? i don't think i've ever seen a bassist that does this. i just need this to let me be heard during band practice in my garage and work as a monitor. maybe some small coffee shop gigs. i just got an ampeg 350w(at 4 ohm) head, that will be hooked up to a carvin 2x10 4 ohm cab. and that's it. just the 2x10 alone. will this suffice? but i'm also thinking of adding an 8 ohm 15" or 18" so it's running on 6 ohms. s'this okay? i just don't want it to blow up or croak.
