So many options, so what really matters?

When it comes to car audio there are a lot of brands to choose from. So how do you know what is truly best for you? The truth is you need to do some research and stay away from advertisers that get paid to push a brand. Look for product that deliver the functions and tuning that best fit in your system.

Starting out with a quality audio source is one of the most important. This does not mean a new radio! ANY and all systems can be upgraded by using a DSP or LOC. This is not without its down sides as tunning a dsp does take some knowledge and understanding of acustics and voltage.

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 then 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 future.

Low Level : is 0-8v of signal voltage. This is most commonly found inaftermarket 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 lest you control the signal, its intercity 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 dont 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.
