Product Overview
Power a high-output car audio system with the SoundQubed Q4-3200 16v Q Series 4-channel amplifier. It delivers 520W x 4 at 4Ω, with selectable 2-channel or 4-channel input mode and bandpassable crossovers for shaping each channel’s signal.
This Korean-built Q-Series flagship combines high-speed digital design with Class A/B-like processing. Its plexi backing, oversized heatsink, and Tiffany-style RCA inputs give the amplifier a distinctive finish.
Key Features & Benefits
- High output: Choose between four-channel power or bridged operation for a front-stage and subwoofer setup.
- Bandpassable crossovers: Set HPF and LPF points across the stated ranges, with an X1–X10 multiplier for additional crossover control.
- Flexible input mode: Select 2-channel or 4-channel input to suit your signal routing.
- Signal control: A damping factor of 145 and 95 dB signal-to-noise ratio are specified for the amplifier.
- Heavy-duty construction: Surface-mount components and a heavy-duty PCB are part of its design.
- Protection circuits: Thermal, overload, DC output, short circuit, voltage input, and clipping protection are listed.

Why Choose This Product?
The Q4-3200 offers multiple ways to allocate its four channels. You can run all four channels in stereo, or use channels 1 and 2 for front speakers and bridge channels 3 and 4 for a subwoofer. Its adjustable crossovers provide signal-shaping control within the amplifier, which can remove the need for a separate DSP in many builds.
For a high-output front stage, the source recommends using high-power component speakers with appropriate RMS ratings. The amplifier’s stated output makes matching speakers and system components an important part of planning.
Installation & Compatibility Notes
- Power wiring: 0GA power and ground wiring is required, with a recommended 300A fuse.
- Electrical system: 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.
- Impedance: Minimum impedance is 2 Ohm in stereo and 4 Ohm bridged. Do not bridge into a load below 4Ω; the source warns this can damage the amplifier.
- Mounting space: Allow for the listed overall dimensions of 16.4" / 417 mm long, 9.4" / 241 mm wide, and 2.8" / 73 mm high.
Frequently Asked Questions
Do I need a separate DSP with the Q4-3200?
Not necessarily. Its bandpassable crossovers and X1–X10 frequency multiplier provide crossover control built into the amplifier, which can eliminate the need for a separate DSP in most builds.
What is the minimum impedance for bridged operation?
The minimum bridged impedance is 4 Ohm. The amplifier is also specified for a 2 Ohm minimum impedance in stereo mode.
What power wiring does this amplifier require?
The Q4-3200 requires 0GA power and ground wiring, with a recommended 300A fuse. A high-output alternator and upgraded battery are strongly recommended for sustained high-power use.
Can I use a 2-channel signal source?
Yes. The input mode is selectable between 2Ch and 4Ch, allowing the amplifier to match either signal-routing option.
How does the Q4-3200 differ from the Q4-150ABv2?
The supplied product details list the Q4-3200 at 520W x 4 at 4Ω, compared with 150W x 4 at 4Ω for the Q4-150ABv2. They also distinguish the Q4-3200 by its 0GA power inputs, Korean-built construction, bandpassable crossovers with frequency multiplier, and selectable 2Ch/4Ch input mode.
