Our take on the Power Acoustik RZ52500D 2500W Max Class D Monoblock Car Audio Amplifier 1 Ohm

The Power Acoustik RZ52500D is a five-channel Class D car amplifier that powers four speakers and a subwoofer from one chassis. It is rated at 100W x 4 plus 400W x 1 at 4 ohms, rising to 150W x 4 plus 600W x 1 at 2 ohms, with a bridged option of 300W x 2 plus 600W x 1. A MOSFET PWM supply, variable high- and low-pass crossovers, adjustable bass boost and an included wired remote bass knob cover the basics of a full system build. It suits drivers who want one compact amp instead of separate four-channel and mono units, though the 2-ohm stereo limit and the brand's budget reputation are worth weighing against established five-channel rivals.

Questions and answers

Is the RZ52500D really 2,500 watts?
That is the peak maximum rating. Real continuous output is 100W x 4 plus 400W x 1 at 4 ohms, or 150W x 4 plus 600W x 1 at 2 ohms.
Can it run four speakers and a subwoofer at once?
Yes. It has four full-range channels plus a dedicated mono sub channel, so one amp covers a complete system.
What impedance can I wire my speakers to?
The four main channels are stable to 2 ohms stereo, or 4 ohms bridged. The sub channel is rated at 2 ohms.
Does it include a bass knob?
Yes. A wired remote bass level control comes in the box, along with mounting hardware and a manual.
How do I set the crossovers?
Both high-pass and low-pass filters are variable, so you can keep bass out of the speakers and send only low frequencies to the sub.
What comes in the box?
The amplifier, the wired remote bass control, mounting hardware and a user manual.
