50 Watt Trunk Amp (120-1970) Amplifier Faxback Doc. # 6647 CONNECTING THE AMPLIFIER You can connect your stereo system to low or high-level input. If your stereo system has RCA outputs, connect it to the amp's low-level input for a cleaner, less noisy signal. If your stereo system only has speaker outputs, connect it to the amp's high input terminals. To connect the amplifier to your stereo system, place the amplifier as close as possible to the selected mounting location and follow the appropriate instructions. LOW-LEVEL INPUT Your amplifier has gold plated color RCA terminals for low-level input to match radios and equalizers with RCA-type, line-level outputs. Note: You need a set of 12-foot RCA cables for dash to trunk mounting. We recommend Radio Shack Cat. No. 42-2356. Follow these steps to connect the stereo system's RCA jacks to the amplifier's LOW INPUT terminals. 1. Plug the RCA cable into the car stereo system's left and right RCA output jacks and connect the other end to the amplifier's left and right LOW INPUT terminals. 2. Connect the left speaker's positive (+) wire to the amplifier's positive (+) left terminal. 3. Connect the left speaker's negative (-) wire to the amplifier's negative (-) left terminal. 4. Repeat Steps 2 and 3 to connect the right speaker to the amplifier's right speaker terminal. Note: We recommend 16 or 18 gauge speaker wire. HIGH-LEVEL INPUT If you car radio does not have RCA output jacks, follow these steps to connect the speaker output from the stereo system to the amplifier. 1. Connect the car stereo system's output speaker wires to the amplifier's HIGH INPUT L and R terminals. Note: Be sure you connect the + and - terminals correctly. 2. If the stereo system has only three wires, connect the common speaker wires to both of the amplifier's L and R negative terminals. 3. Connect the left speaker's positive (+) wire to the amplifier's positive (+) left terminal. 4. Connect the left speaker's negative (-) wire to the amplifier's negative (-) left terminal. 5. Repeat Steps 3 and 4 to connect the right speaker to the amplifier's right speaker terminal. (LB/all-06/28/94)
