I have a 100w amp that has a variety of outputs, in particular (2-8 ohm outputs). I dont have a decent cabinet that I can use as it is my first non combo amp. I plan to buy one this weekend. Can I connect my 2 PA speakers (8 ohm) to the amp and fool around at low volumes? The speakers are just single 10 inch speakers as it is just a cheap PA system. Also, how will this sound compared to a 4x12 1960a or 1960av cabinet?
