DS18 DX4 – Deluxe Compact Full-Range Class D Amplifier

DS18 DX4 — Deluxe Compact 4-Channel Full-Range Class D Amplifier (3000W Max)

The DS18 DX4 was designed to deliver massive power in a tiny footprint — compact enough to tuck into a motorcycle fairing or any spot a normal amp won't fit. Its 4-layer micro circuit board keeps it efficient even at low voltage, with full surge protection (speaker overload, short circuit, low-voltage), so it drives your speakers hard and reliably. A go-to for baggers, boats, side-by-sides, and car audio builds where space is at a premium.

Why we recommend it

Serious power-per-size (up to 250W x4), selectable 2/3/4-channel operation, and HPF/Full/BPF crossovers with a 24dB/oct slope for accurate mids, highs, and lows. Multiple turn-on modes (signal / offset / remote) make it easy to integrate with a factory head unit.
