Do you have a question about the CDA9857 and is the answer not in the manual?
Questions and answers
after changing the deck to another vehicle I have no specker out on all outputs & i pushed the reset button several times , eveything works except no speaker output , even on R.C.A.jacks
Possible causes for no speaker output on an Alpine CDA-9857 after changing the deck to another vehicle include:
1. Incorrect Wiring – Ensure the speaker wires are properly connected according to the wiring diagram. Incorrect connections can prevent audio output.
2. Amplifier Connection Issues – If using an external amplifier, check that the remote turn-on wire (Blue/White) is connected correctly and that the amplifier powers on.
3. Blown Fuse – Verify that the fuse for the CDA-9857 in the vehicle’s fuse box has the correct amperage and is not blown.
4. RCA Connections – If using RCA cables to connect to an amplifier, ensure they are securely plugged in and functional.
5. Vehicle-Specific Components – Some vehicles have factory-installed components that may interfere with the deck’s operation. Check if additional adapters or bypass modules are needed.
6. Speaker Damage – If the stock speakers are not functioning, they may be damaged or incompatible with the new deck.
Checking these areas should help diagnose and resolve the issue.
