  • Our take on the SXE Class A/B 4-Channel Full-Range Amplifier 4 x 60 RMS @ 4-Ohm 1200 Watts

    The DS18 SXE-1200.4/BK is a Class A/B four-channel full-range car amplifier rated at 60W x 4 at 4 ohms, 100W x 4 at 2 ohms, and 200W x 2 bridged at 4 ohms. It uses a compact chassis with a fully variable crossover and adjustable gain, so you can tune front and rear speakers or bridge it to drive a sub. It suits budget-minded builds that want flexible power in a small footprint. Against Class D rivals it runs cooler and simpler but is less efficient, so it draws more current for the same output.

    Pros
    • Four channels cover a full speaker setup or bridge to two
    • Fully variable crossover and adjustable gain for tuning
    • Compact Class A/B chassis fits tight installs
    • Rated stable at 2 ohms per channel
    • Bridged 200W x 2 at 4 ohms adds subwoofer headroom
    Cons
    • Class A/B is less efficient than Class D and runs hotter
    • 60W per channel at 4 ohms is modest for power-hungry speakers
    • Needs solid wiring and ventilation in tight spaces
