I have been told there is no simple way to use an aftermarket head unit with the Bose amplifier, even with adapter cables.

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 3 / ORIGINAL POSTEROriginal post

Thanks , is there a special connector to hook up aftermarket radio to stock amp

POST 4Original post

I have been told there is no simple way to use an aftermarket head unit with the Bose amplifier, even with adapter cables. I would really like a definitive answer on this question as I would really like to dump the Becker CDR 23 unit. There are MOSFET units FS but the issue has something to do with the differing ohms throughout the speaker system. Anymore dome this to there car with just a head unit change?

POST 5Original post

Unless you find a head unit that passes fiber optic out to the amp, you have to change both the amp and the head unit. Then depending on the amp, you may or may not have to rewire some of the speakers (namely the sub). The Bose Sub is 1 ohm. As most amps are only stable down to 2 ohms, you have to put the two speakers in the sub box in series to raise the impedence up to 2ohms or your amp will likely burn up.

POST 7 / ORIGINAL POSTEROriginal post

so you must change amp when installing new head unit because of most system is there a diy on this

POST 8Original post

You can get a MOST-HUR, around $500 and will allow you to retain the amp and speakers, otherwise you must change them.

POST 9Original post

Here is a guide that I borrowed (I can't remember which site). Anyway, it gives you a lot of good information. Also, there are literally hundreds of threads out there about it. If you have any specific questions, PM me. Michael
