Our take on the Memphis PRX800.5V2 800W RMS Power Reference Series Class-D 5-Channel Amplifier

The Memphis PRX800.5V2 is a five-channel Class-D car amplifier from the Power Reference series. It is built to run a full system from one chassis: front and rear speakers plus a subwoofer. Its listed ratings are inconsistent, with 400 W RMS and 800 W appearing in different fields, so confirm the per-channel figures with the seller before buying. No current price was provided, so check the live comparison for where it sits against its recent range.

Questions and answers

Is the PRX800.5V2 really 800 watts?
The listing gives conflicting figures: 400 W RMS and 800 W in different fields. Ask the seller for the per-channel RMS rating at 4 ohms and the subwoofer channel rating before you buy.
Can it run four speakers and a subwoofer?
Yes. Five channels let you power front and rear speakers plus a subwoofer from one amp, which is the main reason to choose this model.
Does it fit in a small car?
At about 13 x 7.3 x 2 inches and 6.1 lb it is compact for a five-channel amp. Measure your mounting space and leave room for wiring and airflow.
What is in the box?
The listing does not detail box contents. Expect the amplifier itself; confirm whether mounting hardware and a remote bass knob are included with the seller.
When is the best time to buy?
Car audio amps often drop during holiday sales and end-of-season clearance. Check the price history on this page to see whether the current price is below its usual range.
