Using the High Level input is always the best option. Using the High Level Input, instead of the Low Level Input, and connecting to the speaker output terminals of your amplifier is one of the unique secrets of REL's success.Oct 13, 2021
Is high level input better?
High Level or Speaker Level Inputs Most of the time, the signal coming from the radio is about 10 volts which means less noise and generally better sound quality. With high level inputs instead of the ground from the chassis, the signal comes from the internal electronics of the radio.
Should I use high level inputs on amp?
Most factory radios do not have RCA connections so it is extremely difficult to install any amplifier into your audio system. Amp manufacturers started using high level inputs to allows for easier integration into newer vehicles where so much of their data is controlled from the factory radio.
What is the difference between high input and low input?
The "Hi" input attenuates the input signal, usually by between 10-15dB (about half to a third the original volume). The "Low" input will not do this. Different guitars and basses produce widely varying signal levels.
Can I use both high and low level outputs?
No, it is not recommended connecting the High Level and the Low Level simultaneously. These two inputs are run on the same circuit internally on the REL and will result in far too much gain. Connecting the High Level and Low Level can result in unnecessarily over taxing the REL circuitry.
What is low-level audio signal?
Low-level audio is typically classified as an “un-amplified” signal – usually 4 Volts and lower – transmitted through RCA cables (Fig. 1). There are premium source units on the market capable of higher output voltages on its RCA output jacks than specified above, but these are a special class of radio.

How do you use a high level input on a subwoofer?
What is this? In some cases, the subwoofers will also have high-level outputs. If that's the case with your sub, you can run just one pair of wires from the amp/receiver to the subwoofer (high-level inputs), and then run the wires from your subwoofer's high-level outputs to your front left and front right speakers.
What is the subwoofer high level output for?
So, if you are using a stereo amplifier and speakers for listening to music or movies – and you would like a 2.1 system with a subwoofer – you can use the high-level connection on the sub to filter the low frequencies from the same audio that is going to your stereo speakers.
