Control Accessory
Why choose this product?
When it comes to adding an amplifier or amplifiers to the factory audio system in a modern vehicle, the link4+ does what models from competing brands just can’t. It is compatible with Start-Stop systems, meaning you won’t lose sound at a red light. It also has our best in class adaptive loading, so it works with virtually any OEM system. The link4+ is very flexibly. It 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 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. 4-Channel Matrix Summing Processor (4-in/4-Out) 2ch or 4ch Input Select (Direct, Copy or Sum) Auto Turn-On via DC-Offset or Audio Signal Detect Locking Detachable Power/Speaker Input Terminals Compact Aluminum Chassis w/Detachable Mounting tabs
