Speakers are a very personal choice, my advise would be go to a few dealers in your area & figure out what you like.

Not sure what their speaker's are like but recently I swapped to a Kenwood Excelon deck & amp (tiny class D 4 ch) & have been very impressed. I always overlooked Kenwood as back in the day (when I was big into car audio close to 20 years back), they weren't anything special. Alpine, Pioneer, etc were the brands to have. To my ears, the recent Kenwood stuff is far superior to those brands.

Not really much into car audio anymore (too much of a compromise) but big into home audio. My biggest recommendation would be add as much sound deadening as you can. It does make a huge difference (especially in these rattle traps) & it doesn't matter how much you spend on speakers, they will still sound like crap if the install isn't good.
