I'm looking for a pair of rear deck speakers that will bolt right into where the original Nackamichi's
were. I think these puppies are 4" 2-way?
I looked on crutchfield.com but their 4" speakers are tweeters.
Any suggestions please?
Thanks,
Bob

 

I would do a search and read up on what others have done with their SC's- there are dozens of such threads. If you insist on a "no-drill" install, I'd remove the stock drivers first (do a search on how to do so) and then you can bring the old units to a store to be certain it will fit.

But when you search and read up, you'll discover that it is not too hard to upgrade to larger drivers just by drilling an extra hole or two.
