Lisa,

Did you make sure the wires are correct? There is a positive and negative for the speaker wires. And depending on the speakers the factory radio may not have enough out put power to dirve the speakers. You may have to boost the power to the rear speakers. I'm sure others on the Forum will have some specifics for you. I used to install car stereos but that was before all of the new amps and boosters were available. I know that there are some components that can be added to give you some great sound.

Good luck, and Welcome to the forum, you will be able to get a lot of great info here.
