When you go to Best Buy and listen to all those speakers on the display and pick the best one, be sure to ask if you need an amplifier to boost the sound to those back speakers. I bought some great speakers at Circuit City and they never told me it needed an amp too. They installed them and when I went back to complain how weak the sound was, it was then that they told me oh I need a $200 amp too. I never bought it. Just faded to rear and cranked up the rear speakers loud. That car is gone now
, but I have a new Pontiac with a great sound system and satellite radio too. Love it! Good luck with your speakers!
