DS18 X4 – Ultra Compact 4-Channel Class D Amplifier

DS18 X4 — Ultra-Compact 4-Channel Class D Amplifier (1400W Max)

The DS18 X4 is a micro amp about the size of a cell phone that still packs a serious punch — the answer when you want real power but have almost no room to mount an amp. It's a favorite for baggers and motorcycles (fits right in the fairing), plus boats, side-by-sides, Jeeps, and car audio builds where space is at an absolute premium.

Why we recommend it

Huge power-to-size ratio — up to 140W x4 RMS (1400W max) — with selectable 2/4-channel input and HPF/Flat/LPF crossover, so one tiny amp can drive mids, highs, and tweeters. Easy to hide, easy to install.
