system design.. please help
 

i just purchased a 2015 traverse. not interested in the bass anymore as I'm getting old. i want to build a system thats loud and clear. the traverse has 6 stock speakers front and rear door both have a 6.5" and tweeters in the front pillars. just sold my sub amp (jl 1000/1) and kept my jl audio 300/4 amp for my new system. can anyone give me ideas? would a good set of 6.5 components for the front and rear doors give me a clean loud sound? the jl amp is 75wx4 rms. thanks in advance for any help.

Which JL amp is it?
the JX, the XD, the slash?
For clear sounding front sets, I suggest Focal. Definitely install acoustic dampening in the doors to maximize the performance.
For a current set, look at the Access line. Something more pronounced the Expert polyglass line.
You can get them in matching sets front and back but unless you plan to entertain in the rear as you do up front, I wouldn't suggest it as it burns up money and does nothing for the quality you experience up front.
I'd say run a small sub in the back like the JL Audio 8w1 or 8w3.
If you wont run a sub, then maybe consider the Focal Flax and bi amp the fronts with all 4 ch's of your amp add in an audio control EQ for something cost effective that will help the sound. If you require more mid then the flax then move into the K2 line. These sound like a great set of bookshelves.
