About the Full Range Monoblock Amplifier 5000 WRMS

This is a single-channel Class D monoblock car amplifier rated at 5000 WRMS, built to drive subwoofers with a bass control knob for tuning. Class D keeps it smaller and cooler than an equivalent Class AB amp, and the bass control lets you boost output around the sub's tuning frequency. At $331.99 at Genius Audio USA as of November 3, 2026, it is the only new price listed, so there is no recent range to compare against. Treat the 5000 WRMS rating as a peak-oriented number and check the fuse rating and birth sheet before you buy.

Pros
  • Class D design runs cooler and draws less current than Class AB
  • Bass control knob for on-the-fly subwoofer level
  • One channel simplifies wiring to a single sub or a parallel pair
  • Low price per rated watt at $331.99
  • Compact footprint for the claimed power
Cons
  • 5000 WRMS claim is unlikely to be certified; real output is usually lower
  • High current draw demands a stout charging system and big wiring
  • No multi-channel flexibility; subs only
  • Bass boost can clip the signal if overused
  • Only one new price listed, so no price history to judge the deal

    • Questions and answers

    Is 5000 WRMS realistic?
    Rarely at this price. Most budget monoblocks rated this high make far less on a certified test, and the number often reflects peak or a 14.4V lab condition. Check the fuse rating: a true 5000W amp needs roughly 400+ amps of fusing.
    Will it work with my stock electrical system?
    Probably not at full output. A 5000W-class amp can pull several hundred amps, so plan on the big-three wiring upgrade, a high-output alternator and often an extra battery. On a stock system it will protect or clip early.
    What subwoofers should I pair it with?
    Dual voice coil subs with 2-ohm or 1-ohm final impedance, rated near the amp's real output. Match the sub's RMS rating to the amp's certified power, not its marketing number, to avoid blowing drivers.
    What is in the box?
    Typically the amp, a bass remote knob and cable, mounting screws and a manual. Power and speaker wire are not included, so budget for 0-gauge or 1/0 wiring.
    Is $331.99 a good price?
    It is the only new price listed as of November 3, 2026, so there is no range to compare. Judge it against the fuse rating and birth sheet: if the real certified power is well under 5000W, the value depends on what it actually delivers.
    Does it have a subsonic filter?
    Many amps in this class include one, but confirm on the unit's control panel. A subsonic filter protects ported subs below tuning and is worth having.
