When I upgraded I went thru 3 sets of speakers all the way up to Rockford Fosgate's costing nearly $300 thinking that they would for sure sound good. All three sets sounded horrible until i decided to give these a try and WOW!
You wouldn't think that a set of $150 speakers would sound so darn good but they do. I use Spotify or Pandora to play high quality feed. I don't even need a subwoofer, the bass from them is that good.
I insulated the doors with 3M sound mat and added some dynamat to the inside skin of the doors. When I shut the doors they sound totally different now. They produce a very quality solid sound.
Here are the speakers I added and they come with a cross over network and tweeters. The cross overs and tweeters from the other sets of speakers were so harsh I could not listen to them but these sound awesome.

These can only be purchased at Best Buy.
I also went with an Alpine Amp.

i also disconnected the center speaker.
The stock speakers are total garbage as most who read this probably know.
