The line inputs on the front of the amplifier receive low level, high impedance signals from the low level RCA outputs of the car stereo. The amplifier receives the signals and converts them to high level, low impedance signals to be used to drive the speakers. All of the amplifiers line inputs need to be connected to the car stereo, in order to use all of the speaker outputs.

RCA "Y" Adaptors Not Included
Your car stereo may only has 2 line outputs (left & right), RCA "Y" Adaptors will be needed to split the left and right signals into 2 right channels and 2 left channels, one of each channel for both the front and rear inputs.(See Fig.1)
Shielded RCA Cable Not Included
For best sound performance use Shielded RCA Cables to connect the Line Outputs from your stereo to the Amplifier Line Inputs. Shielded RCA Cables prevent electrical interference from the vehicles electrical system, and also radio frequency interference.
High Level to Low Level Input Adaptor Not Included
If your stereo does not have RCA type output jacks, a high level to low level adaptor will need to be purchased. The high level to low level adaptor takes the signals from the car stereo's speaker wires and converts them to low level, high impedance signals to be used by the amplifier. Install the converter according to the manufacturers' instructions.
Unused Speaker Wires from Head Unit
You must trim the unused speaker wires on the stereo and wrap with electrical tape as shown to prevent a short circuit.
Do not splice RCA jacks directly to the car stereo's speaker wires.
The colors of the jacks on the RCA cables and adaptors shown here are for illustration purposes.
The color of the cables and adaptors that you purchase for installation will vary by manufacturer.
