High Level Input
Amplifier can use high level input from the source units existing
speakers or output if low level RCA jacks are not available on the
source unit. (See installation wiring diagram). The SQLFW110PS
power amplifier is equipped with current sensing so it will detect a
signal from the vehicles source unit. Therefore the remote lead does
not have to be wired to remote lead input on the amplifier.
