  • 3000 watts is a peak-style rating, not clean RMS power
  • Crossover range tops out at 500Hz, limiting midrange tuning
  • Fan-free means it relies on mounting location for cooling
  • First-gen model; later versions may differ

Questions and answers

Is 3000 watts real RMS power?
Treat 3000 watts as the headline total, not a per-channel RMS figure. Expect far less clean power per channel at 4 ohms; check the manual for RMS ratings before matching speakers.
Can it run a subwoofer and four speakers?
It has four channels plus a subwoofer output and is bridgeable, so you can bridge two channels for a sub and run the other two for speakers. That leaves you with a two-speaker plus sub setup rather than four speakers plus a sub.
Does it need a fan or extra cooling?
No fan is built in. Mount it where air can move around the chassis and keep it away from heat sources, since cooling depends on the install.
What comes in the box?
The amp ships with a fuse included. Plan on buying your own power and speaker wiring, and check the manual for fuse rating before installation.
Is $200 a good price?
At $200 at Earthquake Sound as of November 5, 2026, it sits at the low end of its recent range among the two stores that list it new. That makes it a reasonable buy if the specs fit your build.
How big is it for mounting?
It measures about 11-5/8 inches wide, 8-5/16 inches deep and 2-1/16 inches tall. Measure your mounting spot with wiring clearance before buying.
