Need loud and clear 6.5s + tweets

[quackhead 10+ year member]

6x9s are useless in my car, so im only going to be doing the stock tweeters and 6.5's up front.
Basically, what are loud and clear 6.5s that dont break the bank? And what about for tweeters?

I plan on wiring them off of a head-unit until i can get a good 4ch amp later on down the road. Have the factory HU in now thats hopefully going out within a few weeks

you might need some spacers, but depth may not be much of an issue if you are replacing 6x9's.
