Can I improve on Nissan Bose System?

My Altima 2009 has a Bose system with like 9 speakers I think. The 4 door speakers are 150W RMS. System sounds good but wanted to know if I could install my own system and improve on the sound.
I was thinking of installing four 6.5" 175W-190W RMS component speakers with silk tweeters (and a powerful amp) and two 50W 3.5" front dash speakers.
(I had 2 prs of ADS component speakers with silk tweeters in my Pontiac and loved them.)
I don't know how the Bose speakers produce high frequencies (paper cones, etc.) - can't find specs for them.

I will always suggest to just focus on the front stage and sub instead of spending money on rear speakers. Getting a nice flat signal out of that bose system might be tricky tho.

 
I don't want a sub. Just thinking of upgrading the door speakers and front panel. I don't care about the rear panel 6x9 speakers.
The Bose sub is just OK, not well-defined or loud. I think it's a tube sub. (My Logitech 400W PC sub sounds much better.) The Bose highs are OK, not real harsh but I think I can improve on them.
I can't afford those $270 component speakers you linked.
I can only afford something less than $180/pr. because I'm on disability.
I really shouldn't be doing this at all. I've spent a lot of money on expensive guitars and $2000 JBL speakers last few years and I'm in heavy debt.

The bose system sound amazing depending on what type of music you listen to now if you rock some Michael Bolton or Kenny g your bangin lol but in my opinion if your want super clarity and super clean 6.5 are a good start myself mine are all MB Quart and I love them I have six 6.5 in pods I built in my front and rear doors 2 sets of my 6.5 were component sets and the other 2 were coaxial the 4 components are running off a deaf bounce 4080 4 channel machete the other 2 along with D4S-60 V2 mids with a deaf bounce Hannibal 200x4 running those then I went old school I have 2 eclipse 8812 12's running off a PPI PCX 2400 but your budget means everything it's all in what you wanna spend my dude there's cheaper mids that sound clean and clear like kenwood, some kickers, Focal, Cerwin Vega, I could go on and on once you figure out what you can or wanna spend some of the guys on here can point you in a good direction
 
I listen to Robin Trower, Priest, Ozzy, Cream, ZZ Top, Limp Bizkit, Santana, Soundgarden, lots of things. And like clarity at high volume, highs that aren't harsh. My ADS components had silk tweeters and were very nice but can't afford those.
