The Rockville dB13 is a mono Class D amplifier delivering Dyno-certified 750W RMS at 2 ohms and up to 3000W peak for high-impact bass. High-speed MOSFET power supply and optical coupler Class D topology ensure efficient power delivery with low heat and compact size. Fully adjustable 12 dB/octave low-pass crossover (50–250 Hz) and subsonic filter (15–55 Hz) provide precise tuning for a variety of subwoofer loads. Phase control switch and full IC-controlled protection circuitry protect speakers and the amplifier from thermal, overload and short conditions. Includes wired bass remote, mounting hardware, owner’s manual and a tested power birth sheet for verified output performance. 80A maxi fuse and heavy-duty terminals support reliable current distribution for sustained high-power operation. Form factor and cooling design make the dB13 suitable for trunk or under-seat installations where space is limited. Dyno-certified RMS ratings and a conservative peak-to-RMS specification make the amplifier straightforward to match with subwoofers. Engineered for installers and enthusiasts who require a high-output mono amp with flexible tuning controls and proven durability. Backed by Rockville support and a standard warranty, the dB13 balances measurable power, adjustable control and value.
