Step 2:

The following are guidelines you can use to optimize your installation and avoid surprises or down time. Please read the information available for your vehicle. Please let us know if you have any questions, Thank you. 😁
GM | GMC | Cadilac | Buick

-None Factory Amplified Vehicles: The BC will connect at the radio or HMI unit that can be located behind the screen on 2014-2018 models or behind the glove box on select 2018-2024 models.

-Factory Amplified with Bose: The Bose factory amplifier has a signal output of 0-36V and will require an LOC or Amplifier capable of high level input, with that voltage range. The Bose amp can be found in the trunk on either the LEFT or RIGHT side, behind the beauty panels in all Sedans & SUV's. It will be located on the back wall in all Pick-ups equipped with Bose. Some crossovers will have the amp under the center console BUT it can also be the ANC mixxer, in that situation your BC will connect behind the glovebox.

-Factory Amplified with Pioneer: Select 2013-2015 vehicles with the Pioneer amplifier will have it under the steering wheel to the left. (Black metal box)

Ford | Lincon

-None Factory Amplified Vehicles: Ford is by far one of the most universal when it comes to parts across their different models. The radio connection can be found behind the screen below the AC controls (CD player/radio unit). This is a 6x6x4 metal box independent of the screen. Keep in mind, that you can use a FORScan to flatten your EQ and/or delete your ANC. If you plan on replacing the factory speakers, keep in mind that load resistors may be needed. ALL LOCs we offer have load resistance built-in. However if going high level into an amp, you will need to add resistors before the amp.

-Factory Amplified with B&O: The B&O amp can be located behind glove box, behind the fuse access panel. Amps will have branding labels.

-Factory Amplified with Sony: The Sony Amp can be found on the back wall, behind the driver side rear seat. Amps will have branding labels.

Dodge | JEEP | RAM | Fiat

-None Factory Amplified Vehicles: Dodge, Jeep, RAM, Fiat are keeping it classic and leaving the radio connection behind the radio screen. If you plan on replacing the factory speakers, keep in mind that load resistors may be needed. ALL LOCs we offer have load resistance built-in. However, if going high level into an amp you will need to add resistors before the amp.

-Factory Amplified with Alpine: The Alpine amplifier can be found under the steering wheel, to the left or under either of the front seats. This amp is small and can be silver or black, depending on if you have the 9 or 12 speaker system. The ANC bypass (copied by PAC/Stinger and sold for more) will also plug in here.

Manufacturing time is 8-13 Business days when on backorder. ( based on demand )

Our Elite Loopback Harness Accessory is for those who are looking to add a 4+ channel amp for speakers, without needing to run new wire to each speaker location. The Loopback Harness was designed to allow you to use your factory wiring when amplifying your speakers. Saving you time installing; no need to cut/splice into your vehicles wiring. 

This can be customized and built to a full plug and play kit, for example:

  • If you’re adding a 4-channel amp that does not take a high level (minimum 10v) we offer a 4ch processor, a Link4. This will offer 4ch RCA out and remote turn on to the amp.
  • For a 4-channel speaker amp and 2 channel sub amp set up we offer a Link6. This will offer 4ch RCAs to the speaker amp, 2ch RCAs to the sub amp and remote turn on to both amps.
  • For easy tuning and installation, we offer several amplifier options, all of which can take a high level and have a built-in processor. An LC5.1300 will power the doors and offer RCA out to a sub or sub amplifier.

You always have the option of using your own equipment. The harness can be wired to your own Processor or Amp (verify the input voltage before wiring directly). You can add Wire Ferrules or RCA to your harness, depending on what your equipment requires. 

Our Elite LoopBack Harness Accessory was designed as a solution to customers who would order our T-harness but would then have to come back and get the Loopback Harness to finish upgrading their sound system. The Elite System allows you to easily switch from a T-Harness to a Loopback Harness. 

For example: If you started with subs only and originally went with an Elite T-Harness, you have your Base Connector already. You then decide to add an amp for speakers; you can get this Elite Loopback Accessory. Without needing to buy an entire new harness. 


**This will NOT work for vehicles with a factory amplified system. **


 **Loopback Harness currently have a 30-35 business day lead time, this timeframe can vary depending on customizations . **

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.
