Best mono Class D amplifiers
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: Jensen XDA91RB — the safest cheap mono Class D. It's a real 1-channel amp with honest 4-ohm and 2-ohm ratings, a big review base, and it's the least fussy to wire for a single sub.
Who the others suit:
- Taramps HD 3000 — if you're running a 1-ohm sub and want the most output for the money; strong ratings, but it's a 1-ohm-only design.
- Soundstream TXP1.3500D — a compact, well-rated monoblock for tight installs.
- Pioneer GM-DX871 — the step up if you want a name-brand amp with clean power and better build.
- Pyle Invincible / Power Acoustik OD1-7500D — only if you're chasing big "max" numbers on a tight budget; ratings are thinner and the specs are peak, not RMS.
- EXL and the flush-mount monoblock — niche picks for custom or strapped dual-amp builds.
Check the RMS rating at your sub's impedance before buying — that matters more than the max-wattage headline.
