In the market for a decent cab (well decent speakers), and i was wondering, can i run a 16 Ohm cab on its own, from an 8Ohm speaker output? (as my head only has 1 8, and 2 x 4 Ohm outs.)

running an 8ohm amp into a 16 ohm cab is alright. you will probably lose power and maybe quality but it wont hurt it. now running a 8 ohm amp into a 4 ohm cab could fry your amp.
