Are there any upgrades for my non infinity tweeters that are plug and play other than the super tweeters from qtec? Using the stock location as well.

 

Pretty much anything that will fit. Nothing is gonna be "plug and play" with the exception of the original jeep tweeters. I would suggest getting a component set with new 6 1/2" mids to go with the new tweeters. Then the crossover network that would come with them would( likely anyway) have a way to optimize the tweeter levels for the installation.

I don't know, I mean I DO! But what I suggest isn't really what you want. Sorry.
