Ok this isn't a thirdgen car but I have a sidekick that has a bosse cd player two pioneers in the back and the last owner took the two front speakers, I found 2 about the same size out of an old console tv that we are getting rid of, the speakers are good ( I tested them with my home stereo) but if I try to hook these up in my car is there anything I need to know ? And If I had the money I would go with some good speakers but Im broke right now.

 

it would work but remember CHEAP SPEAKERS=CHEAP SOUND
so why waste the time, I would wait until you can do the job right.

 

So I can play the radio on the freeway with out blowing out the ears of the people in the back lol. I don't think they are going to to fit anyway they are a bit bigger than the old ones and not round.
