4-Channel LOC w/Summing and Remote

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.

Underhood ANL fuse holder mount

Our ABS Mounts were first created as a plug and play solution to go with our S.I.K Kits. After years of selling them and with no other solutions on the market, we decided to bring them back by themselves with a new design.

Wāvtech is ahead of the pack

Need auto detecting load resistance? How about when the signal is distorting? Or maybe you need to bring back missing bass? Wāvtech has you covered.

How your signal is delivered Matters !

Audiophile quality signal built with the highest quality materials at the best price! Zero to no resistance means less heat and a better signal.

What Is High Level or Low level?

High level : AKA Speaker level is an amp that can handle an input voltage of 8-40v. This high output is common in factory amplified vehicles or where the
max voltage of a head unit is more than 10v. This is normally identified by a pigtail connection point or via the RCA on the amplifier (must check user manual to verify.) Some amps have a switch for this. NOT all amps have this feature.

Low Level: is 0-8v of signal voltage. This is most commonly found in aftermarket head units or other aftermarket units that use Can-bus. Most passive LOC units output 0-5v so they are considered a low level and are normally RCA to RCA. Modern day ACTIVE LOC units can output 0-10v of signal.

In conclusion an LOC works as an in-line filter that lets you control the signal, its intensity and in some cases the playable frequency range.

If your amp takes a high level and it is within the vehicles factory output range then you don't need an LOC unit and can wire in and out of your amp directly. In some Fords the signal can be flattened at the OB2, furthering the simplification of the installation.
