Pair Runner Series

Pair Runner Series

Our inspiration for the Pair runner comes from the Masterminds at KINGPIN UNIVERSITY in the very hot desert of Nevada USA. The clean wires system as it is called, was the first wire management ruler system to exist. Industrial Automotive Amp Rack Art (as we call it) was born! A fantastic step in the right direction came to our mind when we discovered this system. We understood that for years many had to do this by hand and nothing more, our system is not just a wire ruler. Our Pair Runner, however, seeks to set the bar in a new direction or brush stroke: if you will.

Many evolutions have taken place from the first in-car radio in 1922 by no other than Chevrolet and not available commercially until 1930, cuz they petty 😉. To the invention of the ziptie in 1958, we felt it was time to take the next step! The Pair Runner is not just a wire guide that offers multiple options of wire management it offers multiple sizes to maintain a minimal show of drill holes in close spaces or the fact that it is made out of 1/4 aluminum and iodized in our Lightening Strike Blue! It's also a:

  • Circle jig, 8 circles in 2 inch increments
  • 17.5" straight edge 
  • Weapon 
  • It will also be your guide to our Spider System© coming soon.

Its really a tool for life; of a skill that will hopefully be passed down from one generation to another. We believe in tools that work for you! Not something you will need to rebuy after a few uses. Our soft aluminum build means it will last you a long time. No matter the environment or age, it means low wear and tear on your bits, it means durability. The system will continue to grow into numerus shapes and platforms like amp spec guides. We have big plans for the Car Audio industry in all of our platforms; especially in the way we express our dedication and time to a good run, no matter the distance. Check out the system below! 

Have any feedback please let us know! IT MATTERS

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.
