Input Signal Connections
Low Level Input (RCA)
Lowlevel(RCA)inputsignalispreferredforbestperformance.Typicaltrunk-mount
amplifierinstallationsrequirea17-20footRCAcable.Mosttrucksandunder-seat
applicationsrequirea6-9footRCAcable.UsingtwistedpairconstructionRCAcableswill
minimize noise.
High Level Input (Speaker Wire)
High level inputs should only
be used when RCA outputs are
not available from the head unit.
