Wavtech Mini Series
link300.4mini | 300 Watt 4-Channel Amplifier
A true 4-channel amplifier in a footprint barely larger than a deck of cards. Bridgeable, fully integrated, and built to run a complete front stage and a subwoofer from one tiny chassis.
Real Power in a Tiny Footprint
The link300.4mini measures just 6.4 by 4.5 by 1.65 inches, small enough to hide under a seat or behind a panel where a conventional amplifier will not go. What sets it apart from other compact amplifiers is that it does not give up capability to get there. It produces 50 watts RMS per channel at 4 ohms and 75 watts RMS per channel at 2 ohms, and it is fully bridgeable to 150 watts RMS x 2 at 4 ohms.
Bridgeability is the feature most small amplifiers drop. Here it stays, which means a single chassis can run a set of components up front and a subwoofer at the same time.
50W x 4RMS at 4 Ohms
75W x 4RMS at 2 Ohms
150W x 2RMS at 4 Ohms BTL
Built-In Summing for Factory Systems
Modern factory systems often split the audio across multiple speakers, sending bass to one set and midrange or treble to another instead of a single full-range signal. The link300.4mini handles that internally with built-in summing, recombining those split signals into a usable full-range feed with no outboard processor required. A level trim adjustment then fine-tunes the output of each channel pair after summing.
This is paired with Wavtech's best-in-class line output converter, built-in loading, and the ability to accept up to 40V of hi-level input, so the amplifier ties directly into demanding factory wiring.
A common setup: run channels 1 and 2 in stereo with the high-pass filter for a component front stage, then bridge channels 3 and 4 with the low-pass filter for a subwoofer. That delivers 50W x 2 for the components and 150W x 1 for the sub from one amplifier.
Clean Integration, Easy Setup
The link300.4mini is engineered to drop into modern vehicles cleanly. Adaptive OEM Load Technology keeps factory radios from throwing error messages, differential balanced inputs reject system noise, and auto turn-on works through DC-offset or audio signal detection so no remote wire is required when one is not available. It is Start/Stop system compatible, holding performance steady when the engine cuts at idle.
Variable high-pass and low-pass crossovers at 12dB per octave let you filter each channel pair, and variable gain with a clip LED makes level matching straightforward. The compact aluminum chassis uses detachable mounting tabs and 4-gauge power and ground terminals, with Active Thermal Management keeping it composed under load.
Footprint
6.4 x 4.5 x 1.65 Inches
One of the smallest true 4-channel amplifiers available, built to mount where conventional amps cannot fit.
Flexibility
Fully Bridgeable
Bridges to 150 watts x 2 at 4 ohms, so one chassis runs a component front stage and a subwoofer together.
Signal
Built-In Summing
Recombines split factory signals into a full-range feed internally, with level trim on each channel pair. No outboard processor needed.
Integration
40V Input + Adaptive OEM Load
Best-in-class LOC accepts high-level signal from factory systems and prevents radio error messages.
Tuning
Variable HP/LP Crossover
12dB per octave high-pass and low-pass filtering on each channel pair to separate speakers from a subwoofer cleanly.
Reliability
Active Thermal Management
Holds rated output under sustained load inside a compact aluminum chassis with locking hi-level terminals.
The Compact Amp That Does It All
