Our take on the DS18 FRP-2.5K/RD Amplifier 1-Channel

The DS18 FRP-2.5K/RD is a red Class D mono amplifier built for car subwoofer duty. It runs a single channel with RMS power ratings and a compact footprint, which suits tight installs behind a seat or in a small trunk. Class D designs like this run cooler and draw less current than older Class AB amps, so it fits stock electrical systems better. It is not rated for marine use, so keep it out of boats and wet locations.

Questions and answers

Is this amp good for powering a subwoofer?: Yes. It is a mono Class D amp, which is the usual choice for a single sub or a pair wired together. Match the sub's RMS rating to the amp's RMS output at your impedance.
Can I use it in a boat?: No. DS18 lists it as not suitable for boats. Marine amps are sealed and treated for moisture, and this one is not.
How much power does it make?: DS18 rates it at 2,500 watts peak, with RMS output lower and dependent on impedance and supply voltage. Check the RMS figure at your sub's impedance before buying.
Does it come with a remote bass knob?: DS18 does not list a bass knob in the box contents. Confirm with the seller if you need one, since some versions of this amp line include it.
What gauge wire should I use?: Use heavy-gauge power and ground cable, typically 4-gauge or larger, for an amp in this power class. Undersized wire causes voltage drop and heat.
Where is the DS18 FRP-2.5K/RD Amplifier 1-Channel cheapest?: At Best Buy, for $349.95, as of our latest check.
