The KS 125.4 mini uses a patent pending auto sense turn-on circuit that offers a significant improvement in reliability and operation. No more will the amp unexpectedly turn off in the middle of a song. Instead of relying on the music to supply enough signal to turn on the amplifier on, ARC Audio's new design detects theBTL IC (Chip Amp) used in the majority of stock head units and amplifiers.
To further simplify OEM integration the KS 125.4 mini uses a fully balanced input stage that is switchblade between speaker and RCA input. Simply plugging your stock speaker wires into the RCA's will supply a perfect clean signal to the amplifier and turn it on.
In addition the remote turn on connection, with the flip of a switch becomes a remote turn-on output to connect the rest of your amplifiers.
