Understanding Amplifier and High Level Inputs
When it comes to car audio amplifiers, there are two types of inputs: high-level inputs and low-level inputs. High-level inputs, also known as speaker-level inputs, are designed to accept a signal directly from a car’s factory speaker wires. On the other hand, low-level inputs, also known as RCA inputs, are designed to accept a preamp signal from a head unit.
High-level inputs are typically used when installing an aftermarket amplifier in a vehicle with a factory head unit. In this case, the amplifier is connected directly to the vehicle’s speaker wires, allowing the amplifier to receive a signal from the head unit without the need for an RCA cable.
One important thing to keep in mind when using high-level inputs is that they require a different type of connection than low-level inputs. Instead of using RCA cables, high-level inputs use speaker wire connections. Some amplifiers come with special adapters that have bare wire at the end, which can be connected directly to the vehicle’s speaker wires.
When wiring high-level inputs to an amplifier, it’s important to pay attention to the polarity of the wires. The positive wire should be connected to the positive terminal on the amplifier, while the negative wire should be connected to the negative terminal.
It’s also important to note that not all amplifiers are designed to handle high-level inputs. When choosing an amplifier, make sure to check the specifications to ensure that it has high-level inputs. Additionally, some amplifiers may require a line output converter to convert the high-level signal to a low-level signal that can be used with RCA inputs.
