Description

SoundQubed Q1-8000 — 8,000W Mono Amplifier | Q-Series | 18V Capable

The SoundQubed Q1-8000 is a no-compromise, competition-ready monoblock amplifier built for enthusiasts who demand serious bass and uncompromising power. Rated at 8,000W RMS at 1 ohm (14.4V) and capable of pushing 10,000W at 18V, the Q1-8000 is engineered for high-output daily drivers, dedicated SPL builds, and any system where dominating low-end is the mission. Housed in a compact 22.3" chassis with machined end caps and a factory plexi backing, it delivers competition-grade performance with the premium Q-Series aesthetic.

The Q1-8000 features a Korean Half-Bridge board with robust, workhorse-grade components built to take abuse and keep performing. It includes 3 x 1/0GA power and ground inputs, Tiffany-style RCA inputs, a variable low-pass filter (20–200 Hz), bass boost (0–6 dB @ 45 Hz), and an infrasonic filter (10–50 Hz) for driver protection. Strappable (master/slave) connectivity lets you link two Q1-8000 units for a combined 16,000W system at 2 ohm. With 96% efficiency at 4 ohm and a damping factor of 336, this amplifier is as precise as it is powerful.

Important: The Q1-8000 requires a properly upgraded electrical system. At minimum: 250+ amp high-output alternator, upgraded under-hood battery, 500Ah AGM or 80Ah lithium reserve, Big Three wiring upgrade, multiple 0-gauge runs, and a dash-mounted voltmeter. Consult a SoundQubed dealer or professional installer before purchasing.

Why Choose the SoundQubed Q1-8000?

  • 8,000W RMS @ 1 Ohm (14.4V) / 10,000W @ 18V — Competition-grade output in a compact 22.3" chassis for serious SPL and high-output daily builds.
  • 96% Efficiency @ 4 Ohm — High-efficiency digital design minimizes heat and maximizes power delivery to your subwoofers.
  • 3 x 1/0GA Power & Ground Inputs — Handles the extreme current demands of an 8,000W amplifier with proper multi-run wiring.
  • Strappable (Master/Slave) — Link two Q1-8000 units for a combined 16,000W system at 2 ohm when maximum output is the goal.
  • Variable LPF (20–200 Hz) + Infrasonic Filter (10–50 Hz) — Precise crossover and subsonic control for optimal tuning and driver protection.
  • Bass Boost 0–6 dB @ 45 Hz — Dial in the exact amount of low-end punch your build demands.
  • Full Protection Suite — Thermal, overload, DC output, short circuit, voltage input, and clipping protection for worry-free high-power operation.
  • Korean Half-Bridge Board + SMT Design — Premium components verified with Audio Precision instruments for quality control.

Amplifier & Electrical Recommendations

Subwoofer Pairing: The Q1-8000 is designed to drive high-power subwoofers in the 2,000–8,000W RMS range. It pairs exceptionally well with SoundQubed’s HDX and HDS series subwoofers wired to a 1Ω final load. Use the variable low-pass filter to set your crossover point between 50–80 Hz for most ported SPL builds, and engage the infrasonic filter to protect your drivers below their tuning frequency. For even more output, strap two Q1-8000 units for 16,000W at 2 ohm.

Electrical Requirements — Non-Negotiable: At minimum: 250+ amp high-output alternator, upgraded under-hood battery, 500Ah AGM or 80Ah lithium reserve, Big Three wiring upgrade, multiple 0-gauge power and ground runs, and a dash-mounted voltmeter. Do not rely on the factory gauge. Consult a SoundQubed dealer or professional installer before purchasing.

Frequently Asked Questions

Q: What subwoofers should I run with the Q1-8000?
A: Pair it with high-power subwoofers rated at 1,500W RMS or more — SoundQubed’s HDX3.2, HDX4.2, or HDS3.3 series are ideal matches. Wire multiple subs to achieve a 1Ω final load at the amplifier for maximum power delivery.

Q: Can I run two Q1-8000 amplifiers together?
A: Yes — the Q1-8000 is strappable, allowing you to link two units for a combined 16,000W system at 2 ohm. This requires a fully built-out high-voltage electrical system capable of supporting both amplifiers simultaneously.

Q: What electrical upgrades do I need?
A: At minimum: a 250+ amp high-output alternator, upgraded under-hood battery, 500Ah AGM or 80Ah lithium reserve, Big Three wiring upgrade, multiple 0-gauge power and ground runs, and a dash-mounted voltmeter. Do not attempt to run this amplifier on a stock electrical system.

Q: Is the Q1-8000 good for daily use or competition only?
A: The Q1-8000 is built for high-output daily drivers and SPL competition alike. With the proper electrical system in place, it can be run daily — but it demands a fully upgraded vehicle electrical system to perform safely and at rated power.
