Product Description

The Reference 300 Watt subwoofer amplifier 311a features a 12dB per octave electronic crossover, allowing you to optimize bass performance based on enclosure type and subwoofer selection. High-output PWM MOSFET power supply ensures optimum power delivery into numerous impedances with low distortion. Full-range preamp outputs facilitate use of multiple amplifiers without the need for noisy and expensive adapters or signal splitters. Dynamic Bass Optimization (DBO) circuit provides variable filtering with adjustable "Q" below 100Hz, far beyond conventional "Bass EQ" circuits, by allowing the low-frequency output to be optimized for specific subwoofer applications.

Mucho Bass!
By Alexander Contreras
I have bough cheap Sony and Pioneer amps at big box stores that said 600 or 1000 watts only to sound like 50-100 watts, so I was not expecting this to be very loud. It's only mounted to a 10" mtx sub that's about 8 years old and has been in 5 different cars and even mounted in my room behind my couch for a while. They just don't make them like they used to, or so I thought, this amp blew me away!At 150 watts, because I am only using one channel, it shook my poor Nissan Altima to pieces. It was so incredibly deep and loud I was very impressed. As always your results may vary depending on type of wiring, deck, input source and sub layout. But I do not think anyone will be disappointed with this amp. It's great, loud, runs cooler than most, and is at a great price.
