DR-2125.2D + RWK41

This bundle pairs the Crunch DR-2125.2D 2-channel amplifier with a Rockville RWK41 4-gauge wiring kit for a system that can run stereo speakers or bridge down to a single high-power subwoofer channel. The DR-2125.2D runs in Class D, rated at 2125 watts max, delivering 2 x 530 watts at 4 ohms in stereo or bridging to 1 x 2125 watts at 4 ohms when wired mono, so the same amplifier can serve either a set of speakers or a subwoofer depending on how the system is configured. SPEED-FET MOSFET output devices and a QTD aluminum heat sink keep distortion low and manage heat across both modes, while a fully adjustable 12dB crossover on both the high and low pass sides lets you dial in the frequency range per application. A built-in LED VU meter shows audio level in real time for quick gain reference. 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 terminals and split loom for a clean install. Buying the amp and matched wiring together removes the guesswork of sizing cable to this amplifier’s power draw in either configuration.
