The OPTI series of monoblock amplifiers pack a huge punch. These digital amps are equipped with single-channel class-D amplifiers for greater power efficiency, meaning you'll get a bigger sound with less power. The OPTI2001D pushes up to 2000 watts RMS power at 0.5 ohms. It's equipped with several variable filters and boosting options, including a low-pass filter, subsonic filter, bass boost, and bass frequency. OPTI amps are bridgeable for increased power. Nickel plated screw terminals provide low-noise connections between the amplifier and your speakers. Remote subwoofer level control lets you easily adjust the bass. And this amp is equipped with thermal, overload, and short circuit protection, so you know your equipment is safe and secure.
