First APT CSVT this is not english class, while your intentions may be good its rather annoying to hear someone tell you to use proper english and they may be less likely to post and share the experience they have..and c'mon big guy is missing a comma or a period going to hurt that much?

anyway
before you spend money replacing all 4 speakers. I'll let you know what I did to handle this situation and hopefully it will help you.
First I purchased a sub and amp combo, then I removed my rear speakers to help vent the bass in from the trunk into the cabin. Once I did this I noticed the front stage in my car noticeably increased..maybe I should say audibly? =) anyway..I still couldnt turn my front speakers up enough to keep up with the bass so I purchased some "bass blockers" (there capacitors that block lower frequencies) this allowed me to play my music louder and not have the stock speakers distort. a good explanation of bass blockers can be found here:

You can get a nice set of entry level Focal 6.5's from
www.zalytron.com for cheap and then purchase a small amp this one is nice:

If you'd like to see a picture of the Focal component set just let me know, mine just came in and I can scan in a pic or two if you'd like.
I hope this huuuuuuuge post proved helpful,
