Join the ranks of car audio enthusiasts who choose Alpine with this ride-rocking bass package. You'll enjoy the performance of an Alpine mono amplifier and two Type-E 12" subs, along with a sturdy Q-Logic subwoofer box — at a significant savings. Just add wiring for a complete bass system in your car.

Two Alpine Type-E SWE-1242 12" subwoofers provide pounding low frequency response, thanks to Kevlar-treated pulp cones and sturdy rubber surrounds. The included Q-Logic hatchback box provides a perfect home for the subs, ensuring powerful, clean bass.

The MRP-M450 mono amplifier pumps out 200 watts RMS to each subwoofer. The variable frequency filter adjusts amplifier output for the best possible sound from your sub, while a subsonic filter eliminates power-wasting, inaudible low frequencies. Dial in some extra low-end kick with the variable bass boost. Preamp- and speaker-level inputs let you connect the amp to almost any car audio system.
