Mike, it sounds like you just want decent (pun intended) spend $100-200 and an afternoon replace all 4 speakers. Crutchfield is a good source for info at fair prices. I also Googled Crutchfield coupon code and got an extra $20 off per pair of the Focal speakers that they had in their clearance bin. I wasn't impressed with the sound at first ( no bass) but after what seemed to be close to 100 hours they've broken in and have good sound. The bass is only as good as 5x7 / 6x8 coax car speakers can be but it was a huge improvement for the $ and time invested. I wasn't looking for stupid loud bass I just like accurate sound.
