What to know when changing car in dash receiver?
basically choosing a receiver is up to you. look for what you want such as the features(ipod/bluetooth,dvd,mp3) the main specific is just make sure the radio you get is not over size for your car such as double din. I have seen what kind of radio fits in your car pretty much anything should be good as long as you don%26#039;t get a double din radio. But as far as regular radios you will be OK and in dash any where from 5 to 7inch screens you will be OK. even a 1 din in dash will be OK. Also you will need a car stereo install kit and a wiring harness to make the install quick and easy. The speakers wise I would change them out to aftermarket speakers. Depends the stock speakers in the car have paper cones which deteriorate over time bad causing distortion and cracking. then with a new radio it will up the bass a bit causing these speakers to go worse quicker.So i would upgrade and you don%26#039;t have to spend that much either. You can probably get all around pioneer for less than 100 bucks just look around you know. here are few websites for radios and car speakers
