Mono Class D amplifier

The DS18 SXE-2500.1D/BK is a mono Class D car amplifier built to drive subwoofers in a vehicle audio system. It delivers 2500W peak power with 800W RMS at 1 Ohm, 600W RMS at 2 Ohms and 300W RMS at 4 Ohms. The frequency response covers 10Hz to 250Hz and the signal-to-noise ratio is 90 dB. Its compact black chassis fits into tight installation spaces.

Subwoofer-only installs

This amplifier suits builds that need a single high-power channel for low-frequency reproduction. It is not for systems requiring multiple channels for full-range speakers or component sets. Buyers who want stereo or multi-channel output should look at a different amplifier topology. The minimum load of 1 Ohm also means it cannot drive loads below that impedance safely.

1 Ohm stable RMS rating

The key specification is the 800W RMS power rating at a 1 Ohm load, which decides whether the amplifier matches the subwoofer wiring plan. If the subwoofer presents a 2 Ohm or 4 Ohm load, the available RMS power drops to 600W or 300W respectively. Matching the amplifier’s stable impedance to the subwoofer configuration determines the actual output the system will deliver.

Questions about this item

How do I wire the SXE-2500.1D/BK to a 1-ohm load without triggering protect mode?

Connect the subwoofer voice coils in parallel to present a 1-ohm load; verify the final impedance with a multimeter before powering on, as wiring it below 1 ohm will activate the protection circuit.

Will the internal cooling fan on the SXE-2500.1D/BK need cleaning or replacement?

The Class D heatsink relies on passive convection; no serviceable fan is fitted, so only occasional dust removal from the finned chassis is required.

At what point does the SXE-2500.1D/BK hit thermal limit during extended bass playback?

Sustained output at 800 W RMS into 1 ohm will raise heatsink temperature until the thermal protection engages, typically after several minutes of continuous heavy programme material.
