  • 80–90 % efficiency keeps the electrical system cool
  • 4 × 220 W RMS at 2 Ω drives four speakers cleanly
  • 2 × 450 W RMS bridged powers a subwoofer pair
  • Full-range response covers mids, highs and subs
  • Compact aluminium heatsink fits tight install spots

PRV Audio QS800 4 Amplifier

The PRV Audio QS800 4 is a four-channel car amplifier rated at 800 watts total. It uses a regulated Class D design to deliver full-range frequency response for daily car audio systems.

Best for Full-Range Systems

This amplifier suits owners who want one compact unit to drive midbass, midrange, tweeters or full-range speakers. Buyers who need a dedicated monoblock for subwoofers only should look at something else.

2-Ohm Stability Per Channel

Each channel is rated at 220 watts RMS into 2 ohms, allowing multiple speakers per channel. If your speaker load is 4 ohms and you cannot bridge channels, the output drops to 100 watts RMS per channel.

Questions about this item

How do I install the QS800 4 in a tight space and what wiring mistake should I avoid?

The compact chassis measures 8 wide by 7 90 length by 2 65 height so it fits in many locations; the step people get wrong is wiring speakers below the 2 Ohm per-channel minimum or below 4 Ohms when bridged, which triggers protection.

What maintenance will the amplifier need over time?

The built-in cooling fan keeps the aluminium heatsink within safe limits; periodically blow dust from the fan vents and verify that power and ground connections remain tight to maintain the 80 90 percent efficiency.

What is the first limit I will hit during extended high-output use?

Thermal protection engages first; the regulated 14 V supply delivers 4 x 220 W RMS at 2 Ohms or 2 x 450 W RMS bridged at 4 Ohms, and sustained demand beyond the heatsink and fan capacity will mute the output until temperatures drop.
