Description
When it comes to adding an amplifier or amplifiers to your factory audio system, the link4 does what models from competing brands just can’t. Simply put, it is the most flexible 4-channel LOC available today.
The link4 can directly accept 4-channels of input and give you 4-channels of output. It can accept 2-channels of input and give you 4-channels of output. If you input 4-channels, you can sum them down to 2-channels of output and pass through another 2-channels for retained sub level control. It even has a 3.5mm Auxiliary Input so you can add your phone or other portable device to the system. No other 4-channel LOC can do all of that.
As an added bonus, it includes our "Patent Pending" Multi-Function Remote Level/Source Control that can adjust your subwoofer output level, the volume of the auxiliary source or serve as a Master Volume Control for your entire system. This is especially useful in OEM systems where speed sensitive volume dependent equalization is present.
