i have a 00 gs3 and i was wondering what are the sizes of the speaker, and how many speakers are there in the car...

also, im thinking about a alpine in dash screeen mp3 player to replace with the stock head unit, would this work with the stock amp and sub? thanks...

 

these questions should be posted on the audio sub-section..

the stock door speakers are 4" for front and rears. sorry but i can't answer the headunit questions.

 

4 inch rounds in the door, 2 ohms. 4 inch rounds in the back, 4 ohms. 2 1 inch tweeters in the a pillars, 4 ohms. One 10 inch sub in the back, 2 ohms. This is if you have the pioneer system.

Mods won't work nicely at all with the stock amp. You could leave the stock sub and run aftermarket everything...but why? Aftermarket sounds better.
