Wavtech link500.4mini 4 Channel Amplifier

The Wavtech link500.4mini produces 75 watts RMS per channel at 4 ohms and 125 watts RMS per channel at 2 ohms across its four channels, with 250 watts RMS x 2 available bridged at 4 ohms, for a total rated output of 500 watts. In 3-channel mode it delivers 125 watts x 2 to the main speakers and 250 watts x 1 to a subwoofer.

Yes, that is exactly what it was designed for. In 3-channel mode, channels 1 and 2 power the front speakers with up to 125 watts each while channels 3 and 4 bridge to deliver 250 watts to a subwoofer. One compact amplifier handles the complete components-plus-subwoofer system, the most common aftermarket audio upgrade.

Channels 3 and 4 of the link500.4mini include a 1-band parametric EQ and a variable subsonic filter. The parametric EQ corrects vehicle cabin resonances at a specific frequency, and the subsonic filter protects the subwoofer from over-excursion below its usable range. Fully adjustable high-pass and low-pass crossovers at 12dB per octave handle the frequency split between the front stage and the sub.

The link500.4mini delivers more power and adds bass processing. It produces 75 watts versus 50 watts per channel at 4 ohms, and 250 watts versus 150 watts per pair when bridged. It also adds a 1-band parametric EQ, a variable subsonic filter, and optional linkRC remote level control on channels 3/4, none of which the link300.4mini includes. The link300.4mini is smaller at 6.4 inches long versus 9.2 inches, so it suits tighter installs with lower power needs.

Yes. The link500.4mini accepts up to 40V of hi-level input with Wavtech's adaptive loading technology, so it connects directly to demanding factory amplifiers without a separate line output converter. Built-in summing with level trim recombines split factory signals internally when no full-range output is present, and differential balanced inputs reject system noise.

Yes, with the optional linkRC remote level control. The linkRC connects to the link500.4mini and adjusts the level of channels 3/4 from the front of the vehicle, giving you a bass knob to fine tune subwoofer output for different music or passengers. The linkRC is sold separately.

Yes. The link500.4mini is Start/Stop system compatible, maintaining consistent operation when the engine cuts at idle and restarts. Auto turn-on works through DC-offset or audio signal detection, so it operates reliably in modern vehicles even when no traditional remote turn-on wire is available.

The link500.4mini measures 9.2 by 4.5 by 1.65 inches, sharing the narrow Mini Series width that fits under seats and behind panels where full-size amplifiers cannot go. It uses 4-gauge power and ground terminals, locking detachable hi-level speaker terminals, and professional-grade panel-mount RCAs. Run 4-gauge power and ground, fuse the power cable near the battery, and ground to clean bare chassis metal.
