Why Choose This Product?
The R2-250X1 combines a dedicated mono bass channel with controls for shaping how that channel integrates into your system. The adjustable crossovers and 15 Hz–40 Hz infrasonic filter let you tailor the signal for your bass path, while the 0 to +18 dB tone control at 45 Hz gives you another way to adjust bass presence.
Balanced differential inputs and RCA pass-through outputs support system integration, and the included remote puts bass-level adjustment within reach while driving. Its cast aluminum heat sink, convection cooling, and protection features are part of its design for music playback.
Installation & Compatibility Notes
Check that your subwoofer or bass channel uses a supported 2Ω or 4Ω load. This amplifier is not bridgeable and is designed as a single-channel power stage.
Allow for the amplifier’s 1.9" x 6.8" x 8.1" dimensions when planning an under-seat or trunk location. The power input is 4 AWG, the recommended fuse is 50 A, and the operating voltage is 9–16 VDC. High-level inputs allow connection with factory-radio signals; low-level inputs support compatible aftermarket sources.
