It seems like amps in the sub 500 watt range at 4ohms are real common and popular. I am only now beginning to look at a small rig and don't have a lot of experience with high volumes. Assuming I won't be playing extremely loud music, what kind of venues can a 300, 350, 400 watt head fill? I was recently at a show in a 1000 sqft room with 30 people and the bass player was using 2 ampeg 8x10's and 2 svt's. I enjoyed have the wind knocked out of me, but it didn't seem to practical or necessary. Also, can you realistically drive 2 8ohm cabs (say 2 112's or a 210 and 115) with that much power? Thanks for the advice.
