installed the new head unit and WOW what a difference.. I was told by 3 different stereo stores not to replace the corvette speakers.. There would not be much of a performance difference if any.. Sounds great..

Just curious here, you used the stock speakers with an aftermarket head unit? It's been floating around on the forum that at least an adapter was required. Any info on how this was done?
It would be interesting to know that HU's that require an amp would work with the stock speakers since the stock speakers have there own amps.

vrumvrum....I have installed aftermarket radios into Bose equiped cars for years with no extra parts...dozens of them. I have not in the C5 but plenty in C4's. I did so by turning the amps on with the radios turn on lead and then feed the amp signal with either the RCA cables or speaker leads. Depends on the output of the radio. My fiancee's 2000 Maxima is done just like this. She has an Alpine radio factory Bose speakers and no adaptors. I have installed plenty of the adaptors and have both good and bad luck with them. I am just at the point now that I do not mess with adaptors.

I counted 8 pins going to the C5 speaker. I see a green and black wire going to and leaving the larger speaker and a red and black wire going to and leaving the larger speaker. They both go to the "amp" in the speaker housing.
I see another red and black wire and green and black wire which go to the tweeter. They come directly from the plug that connects the speaker.
Other wires are orange and black; black; yellow and black; another orange and black; another black; and a purple and black.
Any of that make sense??
Do you have to use an aftermarket HU that needs an external amp or will any HU work?

That is alot of wires. You need to determine which wires do what. Something is going to have to be power and ground then there is signal path. I use a volt ohm meter and test wires first with the radio off then with the radio on. Remove the power and ground wires then you can find signal wires. But I believe I have seen a post that gives the pin config here on the forum.
As for the radio I one of two things. Either use the speaker leads directly out of the head unit to feed the amps or cut a set of RCA cables and wire those to the amps and then plug them into the radio. Using the speakers leads is like using a head unit with high output RCA's.
