    • Our take on the MB Quart RA1-750.1

    The MB Quart RA1-750.1 is a class D mono amplifier built to drive a single subwoofer. It delivers 300 watts RMS at 4 ohms, 500 watts at 2 ohms and 750 watts at 1 ohm, with a 50–250 Hz low-pass filter and a 99 dB signal-to-noise rating. It is not bridgeable and not rated for marine use, so it fits car subwoofer setups rather than boats. Against rival mono amps it is a compact, modestly powered option for a single sub, not a high-output competition amp.

    Questions and answers

    How much power does the RA1-750.1 make?
    It is rated at 300 watts RMS at 4 ohms, 500 watts at 2 ohms and 750 watts at 1 ohm. Match your subwoofer's impedance and RMS rating to one of those figures.
    Can I use it in a boat?
    No. MB Quart does not rate this amp for marine use, so moisture and salt exposure are not covered. Choose a marine-rated amplifier for boat audio.
    Can I bridge two of these amps?
    No. It is a single-channel mono amp and is not bridgeable. Use one amp per subwoofer or step up to a multi-channel model.
    What subwoofer should I pair with it?
    A single sub rated near 750 watts RMS at 1 ohm, or near 500 watts at 2 ohms, gets the most from it. A 4-ohm sub works too but sees only 300 watts.
    Does it have a low-pass filter?
    Yes, adjustable from 50 to 250 Hz. Set it just above your sub's upper range to keep vocals out of the sub.
    What is in the box?
    The amplifier and its mounting hardware. Wiring and a remote bass knob are not included, so plan for an amp kit separately.
    Where is the MB Quart RA1-750.1 cheapest?
    At Best Buy, for $183.99, as of our latest check.
