SoundQubed Q4-3200 — 4-Channel Amplifier | Q-Series Flagship | 520W x 4 @ 4Ω
The SoundQubed Q4-3200 is the flagship 4-channel amplifier of the Q-Series lineup — a high-speed digital amplifier with Class A/B-like processing in a Class D footprint. Imagine if Class A/B and Class D had a baby — this is it. Delivering 520W x 4 at 4Ω, 800W x 4 at 2Ω, and 1,600W x 2 bridged at 4Ω, the Q4-3200 is built for enthusiasts who demand serious power, precision crossover control, and flagship-grade build quality. Korean-built, with a standard plexi backing and oversized heatsink, it looks as good as it performs.
The Q4-3200 features fully bandpassable crossovers with a selectable band-pass (X1–X10) crossover multiplier — eliminating the need for a separate DSP in most builds. The HPF range covers 20 Hz–8 kHz and the LPF covers 50 Hz–8 kHz, giving you precise control over both the top and bottom sides of the slope across all four channels. Input mode is selectable between 2-channel and 4-channel, adapting to your specific signal routing needs. With a signal-to-noise ratio of 95 dB, 87% efficiency at 4 ohm, a damping factor of 145, and Tiffany-style RCA inputs, the Q4-3200 delivers exceptional audio quality with a touch of elegance.
Stable at 2Ω in stereo and 4Ω in bridged mode, the Q4-3200 is protected by a full suite of thermal, overload, DC output, short circuit, and voltage input protection circuits. With a 0GA power input and 300A fuse rating, it’s engineered to handle the current demands of a serious high-power 4-channel build. Surface mount component technology and a heavy-duty PCB ensure reliable, durable performance even in the most demanding conditions.

System Configuration Recommendations
High-Output Front Stage: Run all four channels at 2Ω for 800W per channel to a full set of high-power component speakers. Use the selectable HPF with the crossover multiplier to dial in your exact crossover point without a DSP. At this power level, high-quality component speakers with appropriate RMS ratings are essential.
Front Stage + Subwoofer: Use channels 1/2 for front component speakers (HPF filtered) and bridge channels 3/4 for a subwoofer (LPF filtered) for 1,600W of subwoofer power. The bandpassable crossover and multiplier give you DSP-level control from a single amplifier.
Electrical Requirements: The Q4-3200 requires 0GA power and ground wiring and a 300A fuse. A high-output alternator and upgraded battery are strongly recommended for sustained high-power use. A dash-mounted voltmeter is advised for monitoring system voltage under load.

Frequently Asked Questions
Q: Do I need a DSP with the Q4-3200?
A: Not necessarily — the Q4-3200’s fully bandpassable crossovers with X-Over frequency multiplier (X1–X10) give you DSP-level crossover control built into the amplifier. For most builds, this eliminates the need for a separate DSP unit.
Q: What’s the minimum impedance for bridged mode?
A: The Q4-3200 is stable at 4Ω in bridged mode and 2Ω in stereo mode. Do not bridge into a load below 4Ω — this will damage the amplifier.
Q: What’s the difference between the Q4-3200 and Q4-150ABv2?
A: The Q4-3200 is the flagship model — significantly more power (520W vs. 150W x4 @ 4Ω), 0GA power inputs vs. 4GA, Korean-built construction, bandpassable crossovers with frequency multiplier, and selectable 2Ch/4Ch input mode. It’s built for serious high-output front stage and competition builds.
Q: What wiring do I need for the Q4-3200?
A: 0GA power and ground wiring is required, along with a 300A fuse. A high-output alternator and upgraded battery are strongly recommended for sustained high-power use at full output.
