The BA2100 is a 2 x 100 watt amplifier at 4 ohms, but is bridgeable to 2 ohm mono, making it the perfect amplifier to boost up your top end a bit, or even drive a couple 12 inch component subwoofers. The crossover can also work as High-Pass, too, so if you're building a MONSTER system, the 2100 will tackle the duties of making your highs perform beyond your wildest expectations!
