I'm working on a rig right now and I haven't decided if I'm going to be using too much power. Pre- tech21 power- stewart world 1.2 Bridge 8ohms700w 4Ohms1200w Cab- Swr 3 Jr 2x10 rated for 350 watts 8 ohms. I'm doing this because I'm thinking of adding another cab down the road. If you were wondering about the cabs down the line I was thinking another swr 2x10 and another stewart 1.2 and 2 acme low b2 2x10s. This way I can run a crossover.
