Big speaker-door builds and pro-audio full-range systems have never been shy about demanding power. The problem has always been finding a stereo amplifier that can actually supply it without forcing a compromise on channel count, cabinet layout, or budget. The POWERBOX 2 Channel Pro range exists to close that gap, and lands September 2026.

These are not amplifiers built for background listening. They're built for installers and enthusiasts running large-format full-range speakers, pro-audio door setups, and systems where output on tap matters as much as clean signal. If your build calls for real stereo power and low-impedance headroom, this is the range designed around that exact requirement.

The Gap This Range Fills

VIBE's amplifier lineup has always covered two clear use cases. On one side, lower-powered stereo amplifiers built around quality and control — the right choice when refinement matters more than raw output. On the other, high-powered mono amplifiers, purpose-built for bass and subwoofer duty where a single channel needs to move serious current.

What's been missing is a stereo amplifier that behaves like those mono units in terms of output, without giving up the second channel. POWERBOX 2 Channel Pro is that amplifier. It keeps full 2-channel stereo operation while delivering the kind of per-channel output previously reserved for mono, bass-focused designs — making it the natural choice for full-range speakers and pro-audio door systems that need both channels working at high power simultaneously.

1 Ohm Stereo Stability: Why It Matters

The headline spec across the range is 1 Ohm stability on both channels, at the same time. That's not a bridged-mode party trick — it's full stereo operation with each channel independently capable of driving down to 1 Ohm.

For speaker-door and pro-audio installs, this matters in a very practical way. Multiple drivers per side are routinely wired down to low impedances to extract maximum output from a single amplifier channel. An amplifier that only holds up at 2 or 4 Ohms limits how a system can be wired and how much output is realistically available. 1 Ohm stability per channel removes that ceiling, giving installers room to wire for output without needing a second amplifier or a mono bridge just to get there.

The result is a clean progression across the range — 500W, 700W, and 900W RMS per channel at 1 Ohm — so the amplifier can be matched to the system rather than the system being limited by the amplifier.

Entry of Range

The entry point into the 2 Channel Pro range, and still built to move large full-range and pro-audio speakers with authority. 2 x 500W RMS at 1 Ohm gives real headroom for low-impedance door builds, with a bridged 2 Ohm rating of 1,000W for single-channel applications that need it.

RMS @ 4 Ohms	2 x 190W
RMS @ 2 Ohms	2 x 310W
RMS @ 1 Ohm	2 x 500W
Bridged @ 4 Ohms	1 x 620W
Bridged @ 2 Ohms	1 x 1000W
Frequency Response	10Hz–20kHz
Crossover	LP / HP, 20Hz–12kHz
Dimensions	221 x 122 x 46.5mm

Mid Range

The middle step in the range, built for installs that have outgrown 500W but don't need the top-tier output of the 900. 2 x 700W RMS at 1 Ohm and a bridged 2 Ohm rating of 1,400W make it a strong fit for larger full-range door setups running multiple drivers per side.

Configuration	Stereo / 2 Channel
Topology	Mini Class D
RMS @ 4 Ohms	2 x 270W
RMS @ 2 Ohms	2 x 470W
RMS @ 1 Ohm	2 x 700W
Bridged @ 4 Ohms	1 x 940W
Bridged @ 2 Ohms	1 x 1400W
Frequency Response	10Hz–20kHz
Crossover	LP / HP, 20Hz–12kHz

Range Flagship

The flagship of the range, built for the most demanding full-range and pro-audio door systems. 2 x 900W RMS at 1 Ohm per channel, with a bridged 2 Ohm rating of 1,800W for installs that need maximum single-channel output.

Configuration	Stereo / 2 Channel

Compact Mini Class D Engineering

Getting 500–900W per channel at 1 Ohm out of a chassis this size comes down to the Mini Class D platform each amplifier is built on. It's an efficient topology that keeps physical footprint down without giving up the current delivery needed for low-impedance stereo loads — a genuine consideration for door installs and pro-audio racks where space is at a premium.

Each amplifier uses a custom-designed aluminium heatsink to manage the thermal load that comes with sustained high output, and the chassis itself has been laid out with installation in mind — connections and controls positioned for easy access once the amplifier is in place, rather than an afterthought. Power and Protect LED indicators give an at-a-glance status check on the amp without needing to pull it back out.

High Output Without the Premium Price Tag

The POWERBOX 2 Channel Pro range isn't positioned as a premium audiophile line — it's built for output. Where VIBE's SQ-focused amplifiers are about control and refinement at lower power, and the mono range is about maximum output for a single bass channel, 2 Channel Pro is aimed squarely at people who want serious, usable power across two channels without paying a premium-tier price for it.

That makes it a straightforward fit for full-range speaker builds, large speaker-door installs, and pro-audio setups where the priority is getting enough clean stereo power to the drivers — not chasing the last percentage point of audiophile polish.
