My preference would be to leave the HU in place and just replace the amp.

Suggestion · Original poster

After doing a little digging, it appears as though the Bose amp was used for analog systems, and the Becker amp was used for digital (MOST), which means my car would have the Becker.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

While my CDR23 head unit powers up, I have no audio. It has been confirmed that the amp is dead. My preference would be to leave the HU in place and just replace the amp. Is there a drop-in replacement for the original? I want to use all the original speakers. Thanks!

POST 3 / ORIGINAL POSTEROriginal post

Anybody know which years/models used the same amplifier? There are plenty available on ebay, but not sure if they can interchange.

POST 4 / ORIGINAL POSTEROriginal post

Follow up question - how do I know if I have the Bose system?

POST 5 / ORIGINAL POSTEROriginal post

After doing a little digging, it appears as though the Bose amp was used for analog systems, and the Becker amp was used for digital (MOST), which means my car would have the Becker. If I have that wrong, somebody please correct me.
