Our take on the GTM Series Single Channel Digital Amplifier 3000W Max

The GTM Series is a single-channel class D car amplifier rated at 1500W RMS with a 3000W max figure. That RMS rating is the number to plan around: it suits one subwoofer or a pair wired to a low impedance load. At $174.99 at Genius Audio USA as of November 6, 2026, it is the only new price listed, so there is no recent range to compare it against.

Pros
  • 1500W RMS from a single channel covers most single-sub setups
  • Class D design runs cooler and draws less current than class AB
  • One channel keeps wiring and settings simple
  • Low price per RMS watt at $174.99
Cons
  • 3000W is a peak figure; plan around the 1500W RMS rating
  • Single channel limits you to subwoofer duty, not full-range speakers
  • No listed specs for impedance range, crossover or bass boost
  • Only one store lists it new, so price shopping is limited

Questions and answers

Is 3000W the real power output?
No. 3000W is the max (peak) rating. Continuous power is 1500W RMS, and that is the figure to match to your subwoofer.
What subwoofer should I pair with it?
A sub rated around 1000 to 1500W RMS is the sensible match. Check the sub's impedance and wire it within the amp's supported load range.
Does it have a built-in crossover?
The listed specs do not cover crossover, bass boost or subsonic filter settings. Confirm those with the seller before buying if you need them.
Is $174.99 a good price?
It is the only new price listed as of November 6, 2026, at Genius Audio USA, so there is no recent range to judge it against. Compare it to other 1500W RMS mono amps before deciding.
Can it power door speakers?
It is a single-channel subwoofer amplifier. Door speakers need a multi-channel amp or a separate four-channel unit.
