I just replaced my tweeters in my pods and door speakers because mine were fried. I didn't want to run an amp, simply because I don't care that much about sound. I just wanted working speakers again up front. I ended up buying this Kenwood component set. It was normally $120 and I got it for $69.xx and I couldn't be happier. On deck power they still rock out, tweeters are very nice sounding, crisp and clear. You're never going to get much base out of the door speakers especially if they're 5 1/4, you may with 6 1/2's but these suffice just fine. They also have a built in crossover with a fairly large capacitor to eliminate frequencies that would destroy them. Here's some pics of them......
Took me about 10 minutes per door to install these. The tweeters were a bit big for the pods to mount flush on the outside so I mounted them just like the factory tweeters inside the door sails. OCI Butyl tape FTW also hot glued them in, they're going nowhere. These components came with enough wire also. I simply cut the factory clip off that went to my 5 1/4, took out all the wiring from original tweeter and used these. The spades that connect to the 5 1/4 I cut off then wired the factory wiring into them along with the wires for the tweeters, heat shrinked and done.
