Our verdict

A single channel subwoofer amplifier that accepts high-level or RCA input, so it works with factory radios. It is rated into a two ohm load, which limits which subwoofer wiring will suit it.

Overview

A variable low pass filter and a parametric bass boost are the working controls on this one channel amplifier. Inputs accept either high-level speaker wires or RCA, so a subwoofer can be added without replacing the factory radio.

The amplifier is small and light for its output, and the input choice makes it friendly to stock radios. The listing gives a two ohm rating and nothing about stability at other loads, so the subwoofer wiring has to match.

Who it's for

Drivers adding bass to a factory stereo with a single subwoofer. Anyone running full range speakers from the same amplifier, or wanting a stated high impedance rating, needs a different model.

Pros and cons

Pros
  • Accepts high-level or RCA input
  • Variable low pass filter
  • Parametric bass boost control
  • Light aluminum case
Cons
  • Rated into two ohms only
  • Single channel output
  • Case is freestanding style

Performance notes

The filter removes upper frequencies so the subwoofer only plays low notes, and the bass boost adds output around a chosen point. Actual output depends on a steady supply voltage in the stated range and on wiring the subwoofer to the correct load.
