Another advantage of high level inputs is that the cost is usually much cheaper. RCA cables can be expensive, especially if you need to make long runs. Speaker wire is relatively cheap and although certain amplifiers need adapters, running the speaker wire is much easier and less bulky than RCA cables.
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.
Is RCA high level input?
Low-Level (Line Level) Inputs: Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the amplifier with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers.
Whats better RCA or speaker wire?
An RCA cable is also used to connect a subwoofer or LFE (Low Frequency Effects) output to the subwoofer. Speaker wire, on the other hand, is used solely for hooking up the speakers. Speaker wire also can be used to connect to a passive subwoofer, which is not able to amplify the signal from a line level RCA input.
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.
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.
Do RCA cables go to input or output on amp?
Your amplifier gets its input signals from the receiver's output typically via RCA cables. RCA cables come in stereo pairs, in various lengths. When running new speaker wires from your amplifier's output to the speakers, any size wire from 18- to 14-gauge will work fine.
Do RCA go in input or output on amp?
Your amplifier gets its input signals from the receiver's output typically via RCA cables. RCA cables come in stereo pairs, in various lengths. When running new speaker wires from your amplifier's output to the speakers, any size wire from 18- to 14-gauge will work fine.
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.
