4 channels.
Or two, bridged.
A class AB four-channel amplifier: 60 W RMS x4 at 4 ohm, 90 W RMS x4 at 2 ohm, or 180 W RMS x2 bridged. Full 20 Hz – 20 kHz response, THD below 0.1%, low-pass and high-pass filters on board.
Power, measured not promised
RMS · THD < 0.1% · CONTINUOUS POWER, NOT BURST
Why this amplifier
60 W RMS on each of the four channels at 4 ohm, 90 W at 2 ohm: front and rear from a single chassis, with one power run and one ground.
Bridged, two channels deliver 180 W RMS each at 4 ohm — enough for a pair of midranges or a small subwoofer, without adding a second amplifier.
20 Hz – 20 kHz with THD below 0.1% and a signal-to-noise ratio above 94 dB. Linear class AB topology, not a switching output stage.
Low-pass 50–250 Hz and high-pass 120 Hz–3 kHz, plus bass boost 0–12 dB: the same amplifier drives mids, coaxials or a bass channel.

Complete the system
Before you install it
- Size the power cable and the inline fuse. Use a cable section suited to the current and a main fuse within 20 cm of the battery.
- Clean chassis ground. Ground on bare metal, scraped free of paint, with the shortest cable you can run.
- Leave it ventilated. Class AB heats up: mount the amplifier with free air around it and never cover it with carpet, luggage or foam.
- Set the gain to the source, not to maximum. The input takes 0.2 V to 5 V: match it to your head unit instead of turning the gain fully up.
