Page 10: Input Signal
INPUT SIGNAL (CHOOSING THE HIGH OR LOW INPUTS) The STA amplifer control panel input signal connects to the head unit’s High Level (speaker wire) output OR Low Level (RCA) output—provided the radio is so equipped with Line Out. A dedicated subwoofer or low level signal will deliver the best performance. - Page 11 Fig.4 High Level Connections NOTE: Use 8ga power/ground wire for BATT+ and GND connections. Remote lead is not needed with a High Level connection but is strongly recommended.
- Page 12 Low Level Input and RCA Interconnect Wiring (fig 5) For radios that have RCA line outputs. You will need to connect the low-level RCA style inputs from the STA to the line-outputs from the radio (source) via an RCA interconnect commonly called a “stereo patch cord”. Choose the correct length and style of RCA interconnects for your needs.
