the scoshe adapter is for keeping your factory bose speakers, because each bose speaker has its own attached amp you cant just hook up an aftermarket deck because they put out too much power to the speakers and will burn out the bose amps (or the reverse?!).
hence the scoshe adapter, which basically cuts down the signal strength.

If you are replacing all the speakers with aftermarket like i did (although i did not have the bose system) it wont matter anyways and you can run the speakers directly from the deck (most small scale systems like mine you will never need an aftermarket amp, only when you start making bigger power like adding subs etc.)

otherwise all the adapters are the same with the exception being the scoshe unit.

Now if you do plan on keeping the factory bose speakers and acoustic wave components may i ask why? Ive met people who are nostalgic about keeping that bose system and all i can say is that the bose speakers still used a paper/fibre cone and at the age they are at they are deteriorating quickly. to argue about the quality of a 15 year old speaker is absolutely retarded compared to todays much cheaper yet much more advanced components, true the bose system on these cars was a thing of beauty 15 years ago but nowadays pretty much any no-name, made in china, off the shelf speaker will out perform them in quality and clarity. age does some terrible things to metal cars and even worse things to paper products so i honestly advocate switching over to all new components which can be done easily for pretty cheap. plus with newer speakers most are rated for much more power than most decks can put out on their own (unamplified) which means you have no risk of blowing a speaker by cranking it all the way up. just for fun we hooked up the one old working speaker we had from my car to the new deck and turned it up and now it doesnt make any noise other than intermittant static. the new speakers are heard loud and clear!
