KICKER 48PXA6001 600 Watt Mono Amplifier 1-Ohm Sub Amp for ATV/UTV/RZR PXA6001

The PXA600.1 is a waterproof mono Class D amplifier that puts 600W into a 1-ohm subwoofer load, with 850W of dynamic power, from a chassis only 9-3/4" long. It also handles 500W at 2 ohms or 300W at 4 ohms.

IP66 and IP67 certifications mean dust, direct water jets and temporary immersion are all within spec. That opens up mounting locations a standard amplifier cannot use: under a UTV seat, behind an exposed panel or along an open frame rail on a machine that regularly sees mud and water.

One-ohm stability is what makes the power rating useful. Wire a dual-voice-coil subwoofer down to 1 ohm and the amp delivers its full output, which is how a compact chassis produces bass that a side-by-side cabin can actually feel.

Crossover control uses switches instead of knobs: low pass at 60, 80, 100 or 120Hz at 12dB/octave, with a subsonic filter fixed at 25Hz and a 24dB/octave slope. Bass boost is selectable at 0 or +6dB centered at 40Hz. The CXARC remote is supported for dash-side level control.

Inline power and ground couplers come in the box, and dual turn-on modes cover DC offset or a 12v trigger.
