Alliance Audio VL3200.5 5-Channel Class D Amplifier

The Alliance Audio VL3200.5 is a compact, full-system 5-channel Class D amplifier delivering 4 × 150 watts RMS + 1 × 510 watts RMS at 2 ohms — 3200 watts peak — in a single slim chassis measuring just 35.1 cm × 14.7 cm × 4.8 cm. Designed as the ultimate one-amp solution for enthusiasts who want to power a complete front and rear speaker stage alongside a dedicated subwoofer channel without running multiple amplifiers, the VL3200.5 delivers full-range clarity on channels 1–4 (10Hz–30kHz) and focused, high-output sub-bass on channel 5 (10Hz–260Hz) — all from a single power and ground run. Its Class D topology operates at 80% efficiency, keeping heat manageable across all five channels simultaneously with a max current draw of 110A and a music current draw of 80A.

Channels 1–4 feature an independent high-pass filter (50Hz–250Hz) for precise speaker crossover control, while channel 5 includes a dedicated low-pass filter (50Hz–250Hz), a 0–12dB variable bass boost, and a 0°–180° phase control for seamless subwoofer integration with your front stage. The wide input sensitivity range of 0.2V–6V ensures compatibility with factory head units and aftermarket decks without additional signal adapters, and the included wired sub-level remote puts real-time bass control at your fingertips from the driver's seat. With a damping factor of 100 and an operating voltage range of 8.5V–16V, the VL3200.5 is engineered for reliable, high-performance operation in virtually any 12V vehicle.

At Trinity Car Audio, the VL3200.5 is the go-to recommendation for builds that demand a complete amplified system in a single compact package. Run channels 1 and 2 to a front component speaker set, channels 3 and 4 to rear coaxials or a second component set, and channel 5 to a 10", 12", or 15" subwoofer rated 300–510W RMS in a ported or sealed enclosure. Whether you're upgrading a factory system from scratch or building a clean, space-efficient custom install, the Alliance Audio VL3200.5 delivers the power, precision, and all-in-one convenience to transform your vehicle's audio in a single install.

Why Choose the Alliance Audio VL3200.5?

• Complete System in One Amp: Powers your full front stage, rear speakers, and subwoofer from a single amplifier — one power run, one ground, one install.
• 510W RMS Subwoofer Channel at 2 Ohms: Dedicated high-output mono channel delivers serious sub-bass impact alongside your full-range speaker channels.
• 4 × 150W RMS Full-Range Channels: Clean, high-headroom output for component speakers and coaxials across a full 10Hz–30kHz frequency response.
• Ultra-Compact 4.8 cm Mounting Depth: Fits under seats, in shallow trunk floors, and in tight install locations where stacked multi-amp setups won't go.
• 0°–180° Phase Control on Channel 5: Dial in perfect subwoofer integration with your front stage for a seamless, cohesive soundstage.
• Built-In Crossover Filters: Independent HPF on channels 1–4 and LPF on channel 5 eliminate the need for an external crossover or DSP in most builds.
• Wide Input Sensitivity (0.2V–6V): Compatible with factory head units and aftermarket decks without a line output converter in most applications.
• Wired Remote Sub Control Included: Real-time bass level adjustment from the driver's seat without touching the amp.

System Pairing & Wiring Recommendations

The VL3200.5 is best configured with a front component speaker set (channels 1 & 2), rear coaxials or a second component set (channels 3 & 4), and a single 10", 12", or 15" subwoofer rated 300–510W RMS on channel 5. For channel 5, a dual 2-ohm DVC subwoofer wired in parallel to 2 ohms will deliver the full 510W RMS output. Set the high-pass filter on channels 1–4 between 80–100Hz to protect your speakers, and the low-pass filter on channel 5 between 80–120Hz for clean subwoofer integration. Use the phase control to align the subwoofer's output with your front stage — start at 0° and adjust by ear. Wire the amp with a minimum 4-gauge power and ground cable; for builds pushing all five channels at full output, consider upgrading to 1/0-gauge to minimize voltage drop. Install an appropriately rated inline fuse within 18 inches of the battery.

Frequently Asked Questions

Can the VL3200.5 power a complete car audio system by itself?
Yes — that's exactly what it's designed for. Channels 1 & 2 handle your front speakers, channels 3 & 4 handle your rear speakers, and channel 5 drives your subwoofer. One amp, one power run, complete system amplification.

What subwoofer pairs best with channel 5?
A single 10", 12", or 15" subwoofer rated 300–510W RMS is ideal. A dual 2-ohm DVC subwoofer wired in parallel to 2 ohms will deliver the full 510W RMS output from channel 5.

Can I use the VL3200.5 with a factory head unit?
Yes. The 0.2V–6V input sensitivity range is compatible with low-voltage factory outputs in most vehicles. No line output converter is required in the majority of OEM applications.

What power wire gauge do I need?
Use a minimum 4-gauge power and ground cable. With a max current draw of 110A across all five channels, install an appropriately rated inline fuse (100–110A) within 18 inches of the battery. For builds running all channels at full output, upgrading to 1/0-gauge is recommended to minimize voltage drop.
