Questions and answers
Hi, I **** trying to hook up my amplifier to my stero but not sure what I'm doing wrong I have two rca out lines but those aren't working
To connect a Pioneer GM-D8601 amplifier to your stereo using RCA outputs:
1. Check Compatibility: Ensure your stereo has RCA outputs. The GM-D8601 can accept both high-level (speaker-level) and low-level (RCA-level) signals.
2. Use the RCA Outputs: Connect the RCA cables from the RCA output jacks of your stereo to the RCA input jacks on the amplifier.
3. Automatic Signal Detection: The GM-D8601 automatically detects the input signal mode (RCA level or speaker level), so there’s no need for additional adjustment.
4. Power Connections: Ensure the amplifier is properly powered with connections to power, ground, and remote turn-on.
5. Remote Turn-On: If your stereo has a remote turn-on output, connect it to the amplifier's remote input. If not, the amplifier can automatically turn on when it detects a signal from the RCA inputs.
6. Speaker Connections: Connect your subwoofer or speakers to the amplifier’s speaker output terminals.
7. Test the System: Once everything is connected, turn on your stereo and verify that the amplifier powers on and produces sound through the connected speakers or subwoofer.
Make sure all connections are secure and properly insulated to avoid shorts.
