I use a studio master powered mixer 120 watts each side at 8 ohms more than enough for small bars and clubs. 2 peavey impulse 15" speakers. good 16 gauge speaker wire is ok unless you are going over 75ft then i would use 14. 1/8 mini to 1/4 unbalanced is the right way to go, or mini to rca whatever your mixer takes. plug 1/4 into left chan mono on your board. also you might try an adapter to lift ground to elim hum.also if you have a 400 watt amp, at 8 ohms it is always 400 watts. all the knobs on the amp do is control how much signal goes to the amp. they are not ajustments like 0 to 400 watts. Hope This Helps you. Good Luck, Bob
