Description
Wavtech LINK400.4MINI 400W RMS Compact 4-Channel Bridgeable Amplifier
A compact bridgeable amplifier with matrix summing, channel 3/4 bass tuning and factory-system integration.
Build a factory or aftermarket audio upgrade with the link400.4mini. This four-channel bridgeable amplifier combines matrix summing, adaptive OEM loading and speaker-level inputs up to 40Vrms. Channels 3/4 add a parametric EQ, subsonic filter and support for the optional linkRC remote level control. Start/stop compatibility and active thermal rollback support vehicle integration.
Power for flexible system layouts
The link400.4mini delivers 65 watts RMS per channel at 4 ohms or 100 watts RMS per channel at 2 ohms. Its 4/3/2-channel bridgeable design supports 200 watts RMS x 2 at 4 ohms in bridged operation, with ratings specified at 14.4V and less than 1% THD+N.
Combine and balance factory signals
The four-channel matrix summing processor allows direct, copied or summed channel-pair routing. Adaptive speaker-input loading supports OEM load-detect systems, while +/-6dB output level trim balances channel pairs after summing or copying. Differential balanced inputs accept speaker-level or RCA sources.
Channel 3/4 bass adjustment
The parametric EQ provides 0 to +12dB boost, adjustable Q from 1.4 to 5, and a 30–80Hz center frequency. A 10–50Hz subsonic filter operates at up to -24dB/octave. The optional linkRC adjusts channel 3/4 output from 0 to -30dB.
Two crossover ranges
Variable -12dB/octave high-pass and low-pass filters cover 50–500Hz in the x1 range or 500Hz–5kHz in the x10 range. Gain controls with clip LEDs help set source sensitivity without relying on guesswork.
Vehicle integration and installation
Automatic turn-on can detect DC offset or audio, with a wired remote trigger also supported. Start/stop compatibility and active thermal rollback are built in. The amplifier uses 4AWG power/ground terminals, 10AWG speaker outputs and detachable mounting tabs.
