SoundQubed F1-3000 — 3,000W Mono Amplifier | F-Series Full Bridge | 1 Ohm Stable
The SoundQubed F1-3000 is the entry point of the F-Series monoblock lineup — and it’s anything but entry-level. A full-bridge, digital-class monoblock amplifier delivering 3,000W RMS at 1 ohm in an ultra-compact 9.25" x 8.46" x 2.28" chassis, the F1-3000 packs serious punch in one of the smallest footprints in its class. Part of SoundQubed’s 2024 F-Series lineup, it features an enlarged heatsink for superior heat transfer and an optional temperature/voltage readout on the bass knob — so you can push it hard and stay in control.
The F1-3000 features a full-bridge digital amplifier design with a signal-to-noise ratio of 95 dB, 93% efficiency at 4 ohm — the highest efficiency rating in the F-Series monoblock lineup — and a damping factor of 92. It accepts low-level input from 400mV to 4V, features a band-pass fixed crossover with LPF range of 100 Hz–20 kHz, and a bass boost of 0–12 dB at 45 Hz. Power connections are handled via a single 1/0GA input with a recommended 280A fuse. The full protection suite covers thermal, overload, DC output, short circuit, voltage input, and clipping.
With a frequency capability range of 10 Hz to 20 kHz, the F1-3000 is a true full-range monoblock with tons of versatility. Whether you’re running a single high-power subwoofer or building a compact daily driver system, the F1-3000 delivers real output in a platform that fits virtually anywhere.
Why Choose the SoundQubed F1-3000?
- 3,000W RMS @ 1 Ohm — Serious output in an ultra-compact 9.25" chassis — one of the smallest 3,000W amplifiers available.
- 93% Efficiency @ 4 Ohm — The highest efficiency rating in the F-Series monoblock lineup — more power delivered, less heat generated.
- Full Bridge Digital Design — More efficient and more powerful than half-bridge designs at the same physical size.
- Enlarged Heatsink — Superior heat transfer keeps the amp cool during sustained high-power use and extended demo sessions.
- Optional Temp & Voltage Readout — Bass knob with optional temperature and voltage display gives you real-time system monitoring.
- 95 dB Signal-to-Noise Ratio — Clean, accurate signal reproduction even at high output levels.
- Bass Boost 0–12 dB @ 45 Hz — Wide boost range for dialing in the exact low-end punch your build demands.
- Full Protection Suite — Thermal, overload, DC output, short circuit, voltage input, and clipping protection for worry-free operation.
Amplifier & Electrical Recommendations
Subwoofer Pairing: The F1-3000 is designed to drive subwoofers in the 800W–3,000W RMS range. It pairs exceptionally well with SoundQubed’s HDS3.2, HDS3.3, or HDX3.2 series subwoofers wired to a 1Ω final load. Use the band-pass fixed crossover with LPF set between 50–80 Hz for most ported SPL builds. The 0–12 dB bass boost at 45 Hz gives you plenty of headroom to tune your low-end response.
Electrical Requirements: The F1-3000 is compatible with most upgraded electrical systems. You’ll need a high-output alternator, upgraded under-hood battery, and proper 0-gauge power and ground wiring. A 280A fuse is recommended. A dash-mounted voltmeter is strongly recommended for monitoring system voltage under load.

Frequently Asked Questions
Q: What subwoofers should I run with the F1-3000?
A: Pair it with subwoofers rated at 800W RMS or more — SoundQubed’s HDS3.2, HDS3.3, or HDX3.2 series are ideal. Wire to a 1Ω final load for maximum power delivery.
Q: What’s the difference between the F-Series and Q-Series amplifiers?
A: The F-Series uses a full-bridge design vs. the Q-Series half-bridge, which allows more power output in a smaller chassis. The F-Series is also the newer 2024 platform with an enlarged heatsink and optional temp/voltage readout on the bass knob.
Q: What electrical upgrades do I need for the F1-3000?
A: You’ll need a high-output alternator, upgraded battery, and proper 0-gauge wiring. A 280A fuse is recommended. A dash-mounted voltmeter is strongly recommended for monitoring system voltage under load.
Q: Is the F1-3000 good for daily use or competition only?
A: The F1-3000 is built for both — it’s an outstanding daily driver amplifier that also competes at a high level in SPL builds. Its compact size makes it especially popular for builds where space is limited but output matters.
