Audio Systems: auto speakers, buick rendezvous, back doors

Question
I wannt to change my new car factory 6 1/2 speakers. In the front doors 2 way and the back doors 3 way. The radio sounds good.But if I replace them with the best speakers that will fit in the enclosures which I believe are pioneers will the system be much improved. the vehicle is a 2003 Buick Rendezvous. Also any suggestion you have that I to improve system without making any holes or taking up any space that I use for storage. It is an 8 speaker system. 2 tweeters, 4 6 1/2 and 2 6x9 .

Answer
Hello Arthur,
Changing the speakers may not improve the sound of your stereo system. You may also run into speaker impedance problems. However this depends on the speakers that are factory installed. You might want to take a look at the 6X9's to check the impedence of them. I would change these first to see if they make an improvement in the sound of the system.
