DR-2125.1D 2125W Mono Amplifier + RWK41 Amp Kit

This bundle pairs the Crunch DR-2125.1D mono amplifier with a Rockville RWK41 4-gauge wiring kit for a higher-power single-sub setup in one purchase. The DR-2125.1D runs in Class D for efficient power delivery, rated at 2125 watts max and putting out 1 x 2125 watts at 2 ohms or 1 x 1050 watts at 4 ohms, giving enough headroom for larger single or dual subwoofer setups depending on wiring configuration. SPEED-FET MOSFET output devices and a QTD aluminum heat sink keep the amp running cool and distortion low even as output climbs, and a fully adjustable 12dB crossover with onboard bass control lets you shape the low end to the enclosure. A built-in LED VU meter reflects audio level on the amp’s logo for quick gain reference, and the included wired bass remote puts adjustment within reach from the driver’s seat. The RWK41 kit supplies 100% copper RCA cables, 4-gauge power and ground wire, an 18-gauge remote lead, and a 60-amp AGU fuse, plus the terminals and split loom needed for a clean run from battery to amp. Buying the amp and kit together removes the guesswork of sizing wire gauge to this amplifier’s higher current draw.
