Industry leaders or thieves?

Stolen designs

For years people like CAF and 5STAR said you HAD to pull new speaker wire, then we showed up and now they say loops are the way. Don't trust people who copy others and try to take credit.

The year was 2018

Before the solutions were even needed we had them. It wasn't until 2022 that PAC Audio and Metra would have to backstep and steal our design to stay in the game.

The SCAM that is PAC Audio

The amp-pro was PACs first try to steal our ideas. It failed so bad they had to steal our ANC bypasses to make the amp-pro (2019) work better. (pic taken 2017)

What Is "High Level" or "Low level" ?

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 OBD2, further simplifying the installation.

Automotive Amp Racks

We created the Automotive Amp Rack

We created the Automotive Amp Rack

to give customers a secure place to mount their equipment without damaging their vehicles and having the ability to build and test everything outside of the vehicle. Choosing durable materials like ABS, HDPE, Acrylic and always using factory bolts was our mission.

This product has now turned into an upsell by shops and copy-cats like 5star and car audio fabrications on YouTube to be sold as some type of beauty product. Shops are using cheap materials like expanded PVC board and charging customers a premium price for doing something they should have been doing all along. Your choices are get robbed, or screw holes and water leaks.

They do not represent what our products are and we don't appreciate the theft of our products and ideas being used to steal from customers.
