SoundQubed 5000 Watts F1-5000 Full Bridge Monoblock Amplifier

SoundQubed F1-5000 — 5,000W Mono Amplifier | F-Series Full Bridge | 1 Ohm Stable

The SoundQubed F1-5000 is a full-bridge, digital-class monoblock amplifier delivering 5,000W RMS at 1 ohm in a remarkably compact 10.78" x 8.46" x 2.28" chassis. Part of SoundQubed’s 2024 F-Series lineup, the F1-5000 sits in the sweet spot of the monoblock range — enough power to drive serious subwoofer setups, in a platform small enough to fit virtually anywhere. Like all F-Series amplifiers, 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 F1-5000 features a full-bridge digital amplifier design with a signal-to-noise ratio of 95 dB, 91% efficiency at 4 ohm, 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 470A fuse. The full protection suite covers thermal, overload, DC output, short circuit, voltage input, and clipping — keeping your system safe under sustained high-power use.

With a frequency capability range of 10 Hz to 20 kHz, the F1-5000 is a true full-range monoblock — versatile enough for subwoofer-only builds and flexible enough for creative system configurations. Pair it with a quality subwoofer wired to 1Ω and let it do what it was built to do.

Why Choose the SoundQubed F1-5000?

• 5,000W RMS @ 1 Ohm — Serious output in a compact 10.78" chassis — more power per inch than virtually anything in its class.
• 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 extreme output levels.
• Bass Boost 0–12 dB @ 45 Hz — Wide boost range for dialing in the exact low-end punch your build demands.
• Remote Level Control Included — Adjust your bass level from the driver’s seat without touching the amp.
• Full Protection Suite — Thermal, overload, DC output, short circuit, voltage input, and clipping protection for worry-free operation.

Amplifier & Electrical Recommendations

Subwoofer Pairing: The F1-5000 is designed to drive high-power subwoofers in the 1,500–5,000W RMS range. It pairs exceptionally well with SoundQubed’s HDX and HDS 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 F1-5000 requires a properly upgraded electrical system to perform at rated power. You’ll need a high-output alternator, upgraded under-hood battery, and proper 0-gauge power and ground wiring. A dash-mounted voltmeter is strongly recommended. Consult a SoundQubed dealer or professional installer before purchasing.

Frequently Asked Questions

Q: What subwoofers should I run with the F1-5000?
A: Pair it with subwoofers rated at 1,500W RMS or more — SoundQubed’s HDX3.2, HDX4.2, or HDS3.3 series are ideal. Wire multiple subs to achieve 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 F1-5000?
A: You’ll need a high-output alternator, upgraded battery, and proper 0-gauge wiring at minimum. A dash-mounted voltmeter is strongly recommended. Consult a professional installer before purchasing.

Q: Is the F1-5000 good for daily use or competition only?
A: The F1-5000 is built for both — it’s an outstanding daily driver amplifier that also competes at a high level in SPL builds. With the proper electrical system in place, it can be pushed hard every day and handle it with ease.
