sure. BEcuase '97-'99 qualify for SpecBoxster racing with the PCAS. Newer cars do not. Even though the 986 was relatively unchanged from '97-'94, only those cars manufactured prior to '00 qualify. So a "roller", or a rough car, or one with salvage title, or any of those things that make a street car "less desirable" looks like a good basis of a race car to us, if it's pre-'00.
But if you're looking for a street car 986, I'd go with an '03 or '04, if for no other reason than the glass rear window. And I'd get the 'S' for the brakes & the HP.
Regardless, I'm one of the guys who'll tell you the 986 will NEVER be "collectible" in the sense that you should look for just the right car and hold on to it. Get the one you can drive the wheels off of. that will ALWAYS be the best thing this car has going for it. Cheap Thrills.
I think they are 3.5 inch speakers but again I made my own mounts. I found the speakers in the dash and doors were old and torn so I replaced them all. Sorry I couldn't be of more help. I would think they are pretty much standard for such a small speaker.
Hi! Well I bought a Chinese HU off ebay, DD. I upgraded the speakers in the dash and doors the ones I had were shot. I had the rear shelf storage (which I never used) so I added 6 speakers to the rear deck and swapped out the factory amp with a 996 factory 6 channel from a cabrio. I would be glad to give you what info I have but not sure what you are asking? are you looking to replace the speakers in the rear shelf? Do you have the factory speaker package? or are you looking to replace the dash/door speakers? I have a 99 Base and live in RI.
