I hear what you mean lowlyfe83. I had them in my old 1992 SE but that was with tan interior. Didn't look too bad with the tan interior, but with blue I have to admit it might look a bit out of place.
If you are looking looking to add tweeters though it is very easy. Your car is factory wired for the performance sound system, so all you have to do is take your door panel off and plug in some tweeters (or even add a set of 5.25"* or 6.5"*) to the blank speaker connectors.
For speakers I'd suggest picking up some Infinity'* on Ebay. If you get 4" rounds I have a set of 4x6 adapter plates that I no longer need. Yours for the cost of shipping ($3.50 for priority shipping). Anyhow, for the speakers I think Infinity'* are probably your best 4x6 plate speakers. They are kind of like 4" components since the tweeter is seperate from the woofer. I've seen the awesome Infinity Kappa 4x6"* go for as little as $15 for a new set on ebay. Average for 4x6 Kappa'* on ebay is around $35 + shipping and for the Infinity Reference 4x6"* around $25-30 + shipping. I am sure there are better brands, but for the price you can't really go wrong.
