Our take on the CA4-2000 Class A/B 4-Channel Car Amplifier

The Power Acoustik CA4-2000 is a four-channel Class A/B car amplifier rated at 110 watts RMS per channel at 4 ohms and 180 watts at 2 ohms. Bridged, it delivers 360 watts to each of two channels, which is enough to drive a pair of subwoofers or a front-stage component set. The 2,000-watt figure is peak marketing power, not RMS. Class A/B designs like this run hotter and draw more current than Class D amps, so plan on solid wiring and ventilation. It suits budget builds that want one amp to run four speakers or two subs and speakers together.

Questions and answers

Is the CA4-2000 really 2,000 watts?
No. That is peak power. The RMS ratings are 110 watts per channel at 4 ohms, 180 watts at 2 ohms, and 360 watts per bridged pair at 4 ohms.
Can it run two subwoofers?
Yes, in bridged mode. Bridge channels 1/2 and 3/4 to get 360 watts RMS into each of two 4-ohm subwoofer loads.
How does it compare with a Class D amp?
Class D amps are smaller, cooler and more efficient. This Class A/B amp is simpler and common in budget builds but runs hotter and pulls more current.
What speakers can it drive?
Four speakers at 4 or 2 ohms, or a mix of speakers and bridged subs. Check that each channel's load stays at 2 ohms or above.
What do I need to install it?
An amp wiring kit rated for its current draw, RCA cables from the head unit, and a well-ventilated mounting spot. Class A/B amps need more airflow than Class D.
Where is the CA4-2000 Class A/B 4-Channel Car Amplifier cheapest?
At Power Acoustik, for $94.49, as of our latest check.
