The R2 models are developed for car audio fanatics that want a reliable amplifier – with all the power and performance you’ve come to expect from Rockford Fosgate – at an economical price. Rockford Fosgate amplifiers are renowned world-wide for being “under rated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. These 3rd generation of Prime Series amplifiers are refined with the latest Rockford Fosgate technology for easy setup and configuration, making them perfect for use with factory audio or custom aftermarket systems.

Understanding the LLJ Elite System:

The Elite T-Harness allows you to add an aftermarket mono amp/subwoofers while retaining all the features in your vehicle like the Bluetooth, Steering Wheel Controls and OnStar. You are able to build and customize your harness to your preferences and needs; like the length of the harness or adding an LOC unit of your choice. We offer a variety of choices like an Audio Control LC2i Pro, a Link2 or LinkDQ from Wavtech for when you are just adding a subwoofer/s. With an LOC added to the harness you are getting a full plug and play set up; with the harness providing signal and the LOC unit providing RCA out and remote turn on to your amp. By offering our customers the option to customize their harness we also offer the option to use your own LOC unit, you are not limited to using the units we offer. Every harness ordered without an LOC unit will come with a color card to help you wire your own equipment. The harness (with no unit) will come as a 4 channel, allowing you to use either a 2 channel, 4 channel or 6 channel DSP or processor. This T-harness is not only for a mono amp/subwoofer install, you are also able to use this harness if you are planning on replacing your door speakers or installing full system and are planning on running your own wire back to the speakers. It can be purchased with a processor like an Audio Control LC7i or a Link6 from Wavtech, these are 6 channel processors. You also have the option of using a DSP like a DSR1 from Rockford Fosgate or a DM-608 from Audio Control. For a simple, quick and clean full system set up, without the need to run your own wire we offer our Elite Loopback Harness. LLJ Customs is the creator of the OEM Loopback Harness. When the company first began what is now known as the T-Harness and Loop Harness were not a definitive plug and play option available. What was typically found was wiring that needed modifications to the physical harness and add on’s that were not offered. Frustrated with the lack of options available, the extensive research needed and lack of help from audio shops we created something that would help others add new speakers, new amplifiers, new subwoofers and keep everything looking and functioning as factory. The Loopback Harness comes with 2 ends, a signal side and a return side. The signal side will feed into a 4+ channel amp that takes a high level or a processor and returns (or loops back) that amplified signal directly from the output on the amp, to the speaker locations using the factory wiring. This is ideal if you are simply adding an amp to speakers or if you want to add multiple amps and go all out with a complete new system. Our harness grants you the access of your already available and paid for factory wiring. The Loop Harness provides all of this in one consolidated product. It provides the signal, the return and it also provides power up to 10amps for most processor and DSP’s. This means you are only running 2 things, the Loop Harness from the source and the power wire from your battery. In some cars this is especially beneficial as sometimes they have the signal source (radio or factory amplifier) in the trunk along with the battery.

Best Active Line Output Converter (LOC) :

The best Loc you can get is one that offers the features you NEED at a price that makes sence for what you get. Hands down the best LOC on the market is the Bassrestore from Wavtech! This magic box has everything an LOC should be with the fetures that matter.

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.
