Our take on the DS18 FRP-5K/RD 1-Channel Fullrange Monoblock Amplifier

The DS18 FRP-5K/RD is a single-channel Class D monoblock amplifier built for subwoofer duty in car audio systems. It is rated at 5,000 watts peak and roughly 2,500 watts RMS at 1 ohm, so it is aimed at people running one or two heavy subwoofers. Class D operation keeps it cooler and more compact than older Class AB designs, and the red heatsink is a DS18 signature. It is not bridgeable and not rated for marine use, so it suits car builds only.

Questions and answers

What subwoofers can this amp drive?: It is a 1-ohm-stable monoblock rated around 2,500 watts RMS, so it suits one or two high-power subwoofers wired to a low final impedance. Check your subs' RMS rating and wire for a load the amp can handle.
Is it bridgeable?: No. It is a single-channel mono amp, so there is nothing to bridge. If you need more output, you would add a second amp or step up to a larger model.
Can I use it in a boat?: No. DS18 does not rate this amp for marine use, so it is best kept in a car where it stays dry.
Does it need an upgraded electrical system?: At its rated output it draws serious current. Plan on thick power cable, a solid ground and a charging system that can keep up, or it will not reach its rated power.
What is the difference between the peak and RMS ratings?: Peak is a short-burst figure; RMS is the continuous power you can expect. The RMS number is the one to match against your subwoofers.
Where is the DS18 FRP-5K/RD 1-Channel Fullrange Monoblock Amplifier cheapest?: At Best Buy, for $699.95, as of our latest check.
