MTX 3512-02 12" Subwoofer + Alpine Mono Amplifier

This bundle pairs the MTX 3512-02 12" subwoofer with an Alpine KTA-30MW mono amplifier, built specifically for installs where space is tight, such as open-cab vehicles, side-by-sides, and ATVs. The 3512-02 handles 250W RMS through an Inverted Apex surround for stronger volume displacement and Spider Plateau Venting to keep the voice coil cool under sustained bass.

The KTA-30MW measures just 9-3/16" x 1-5/8" x 3-3/4", roughly half the size of a traditional amplifier, so it fits under a dash, in a glove compartment, or inside a saddlebag where a full-size amp won't. It delivers up to 600W of Dynamic Peak Power, Alpine's technology that automatically boosts gain to meet rhythmic peaks in the music, like a snare hit or kick drum, before rolling back down to stay efficient. This keeps the signal from clipping without needing constant manual gain adjustment.

Rated IP66 for resistance to dust and high-pressure water spray, the KTA-30MW is built for exposed installations, including boats, motorcycles, and open-top vehicles, where a standard amplifier would be at risk. Paired with the 3512-02's 125-250W RMS recommended amp range, this combo brings real 12" subwoofer bass to vehicles that typically don't have the space or weather protection for a traditional car audio setup.
