Key Features


German engineering and craftsmanship combine to create a sleek amplifier that'll make your vehicle come alive with crystal-clear, powerful music. The Helix Blue B TWO 2-channel amplifier puts out 80 watts RMS each to your full-range speakers, or you can switch to bridged mode to power a subwoofer with up to 200 watts RMS. Product Highlights: 2-channel car amplifier 80 watts RMS x 2 at 4 ohms (120 watts x 2 at 2 ohms) 200 watts RMS x 1 bridged output at 4 ohms (4-ohm stable in bridged mode) Class A/B design variable low-pass filter (15-4000 Hz) variable high-pass filter (40-4000 Hz) bass boost (0-18 dB at 45 Hz ) speaker-level inputs via 8-pin harness preamp inputs and outputs 8-gauge power and ground leads recommended — wiring and hardware not included with amplifier fuse rating: 30A x 1 11-3/16'W x 2'H x 10-1/4'D Bought a set of Focal Access 165A1 SG components requiring 60 rms each. I went to the Harrisonburg store where I discussed choices with Crutchfield staff whom recommended this amp after reviewing several. It gives me a bit more than required with a birth chart rating over its expected output, as most quality amps do. I am very happy with this amp over all, and had no problems setting it up. I would definitely recommend this amp for similar needs over most other choices for its quality and performance. Pros: Well built, easy to set up, and has more power than it says it does. Cons: None
