18dB Crossovers
Filter out the frequencies your subwoofers can't play and use the power for what they can play via 18dB/octave slope low pass, & subsonic crossovers.
Remote Gain Control
The remote gain control allows amplifier level adjustment from a remote location in the vehicle.
Strap Amps Together
Get double 1 ohm power on a 2 ohm load by strapping two like amps together. All pre-amp adjustments and remote control are done from one Master amp.
All MOSFET Amplifier
BAMF amplifiers use MOSFET transistors for the power supply & output stages. MOSFET transistors increase durability and longevity over bi-polar counterparts...
12db Bass Boost
Utilize a built in 45Hz bass boost for up to 12dB of gain. Get the most power from your BAMF amplifier.
180° Phase Switch
Phase align the subwoofer sound waves with the front speakers so both hit your ear simultaneously. Phase aligning the normally out-of-phase subwoofer sound waves increases the bass your ears pick up.
