rating

SPEAKER: MB Quart QS216 (1-pair) AMP: ? CAPACITOR: ? Looking for amp to match MB Quart speakers rated at 80/170w. Power rating is 4 ohms. I only prefer to shop at sonicelectronix. I found a couple 2channel-ClassAB amps that have an rms ranging from 100-150w. Are there any benefits in going above...
