What speakers do i need for Mazda protege 1999 and how to install them?

I just purchased mazda protege 1999 and sound isn't that good and i need better sound





I know nothing about speakers and sizes, i was told i need to buy 6x9" @ Over 8" for rear for mazda protege 1999 but what about front? And if i am planning on changing rear should i buy front ones too or rear is enough?


and is it easy enough to replace front and rear speakers on mazda protege 1999?|||The front are 6x8 and the rear are 6x9, if you can swing it replace all, as far as installation that depends on your technical skills. If you want to learn more bout speakers, check the link. Good Luck!
