WavTech link300.4mini: Compact 4-Channel Amplifier

Ultra-Compact Design for Maximum Installation Flexibility

The link300.4mini's tiny footprint opens up installation possibilities where space is at a premium. At just 6.4" x 4.5" x 1.65", this amplifier can be mounted in locations that were previously impossible, such as under seats, behind panels, or in compact storage areas. Despite its small size, the aluminum chassis provides excellent thermal management to maintain performance during extended use. The detachable mounting tabs add further installation flexibility, allowing the amplifier to fit in even tighter spaces when necessary.

Advanced Factory Integration Solutions

Today's factory audio systems present numerous challenges for upgrades, from complex signal processing to load-sensing speaker outputs. The link300.4mini addresses these issues with its comprehensive integration features. The differential balanced inputs accept speaker-level signals up to 40V without distortion, eliminating the need for separate line output converters. The built-in signal summing capability combines factory signals that may be intentionally limited in frequency range, reconstructing a full-range signal without requiring external processors. The adaptive loading technology prevents factory radio error messages by simulating the original speaker load.

Versatile Configuration Options for System Optimization

Whether powering a full-range 4-channel system or a component front stage with a subwoofer, the link300.4mini offers the flexibility needed for virtually any configuration. The amplifier can be used in standard 4-channel mode for front and rear speakers, or bridged to create a 3-channel system with stereo front speakers and a mono subwoofer channel. Each channel pair features independent gain controls with clip indicators, ensuring precise level matching without distortion. The variable high-pass/low-pass crossovers (50-500Hz) with 12dB/octave slopes allow precise frequency management for optimal speaker performance.

Premium Audio Performance in a Compact Package

Don't let the small size fool you—the link300.4mini delivers audio quality that rivals much larger amplifiers. The Class-D design provides excellent efficiency while maintaining audio fidelity across the frequency spectrum. With frequency response extending from below 10Hz to beyond 45kHz and a signal-to-noise ratio exceeding 80dB, this amplifier delivers clean, detailed sound that satisfies even discerning listeners. The level trim adjustment feature allows fine-tuning after signal summing, ensuring optimal performance with any factory or aftermarket source unit.

Reliability Features for Consistent Performance

The link300.4mini incorporates numerous protection and reliability features to ensure consistent performance in the demanding automotive environment. The multi-stage protection circuitry guards against thermal overload, short circuits, and voltage irregularities, while the start/stop system compatibility prevents audio dropouts during engine restart cycles. The auto turn-on capability via DC-offset detection or audio signal sensing eliminates the need for a dedicated remote wire in many installations, simplifying the installation process while maintaining reliable operation.
