Our take on the MICRO4-2500D Class D Compact 4-Channel Car Amplifier

The Power Acoustik MICRO4-2500D is a compact four-channel Class D car amplifier. It is rated at 4 x 150 watts RMS at 4 ohms, 4 x 210 watts at 2 ohms, and 2 x 420 watts bridged at 4 ohms, with a 2,500-watt max-power figure. Its small chassis suits tight installs behind a seat or in a side panel, and the four channels can run front and rear speakers or bridge to two subwoofers. Against full-size Class AB four-channels it gives up some rated headroom but saves space and current draw; owners of budget builds tend to accept its inflated max-power claim as marketing.

Questions and answers

Is the 2,500-watt rating real RMS power?
No. It is a peak max-power figure. The RMS ratings are 4 x 150 watts at 4 ohms, 4 x 210 watts at 2 ohms, and 2 x 420 watts bridged at 4 ohms.
Can it power two subwoofers?
Yes. Bridged at 4 ohms it delivers 2 x 420 watts RMS, enough for two subwoofers if they are 4-ohm models wired to each bridged pair.
Does it fit in a small space?
It is built as a compact Class D amp, so it suits behind-seat and side-panel installs where full-size four-channels won't fit.
What speakers can I run on it?
Four 4-ohm or 2-ohm speakers, or two bridged 4-ohm subwoofers. At 2 ohms each channel is rated 210 watts RMS.
Do I need to upgrade my electrical system?
For full output, yes. A Class D amp this size still needs adequate gauge wiring and a healthy battery and alternator to reach its ratings.
How does it compare with a full-size Class AB amp?
It saves space and current draw but gives up some rated headroom and premium build feel. It suits budget builds more than competition systems.
