Just bought my first Grand Prix (going from driving a Cadillac for four years, the GP was a change!).
I've heard about changing the pulley (even heard it gives your car better mileage?), and am considering tinting out the windows a bit -- but I confess I know very little about cars and really can't keep up with the tech talk (anyone care to speak laymen for me =)
Also, put my 2 12's in the day I got my car; anyone notice a slight buzz coming from the passenger side (only during certain frequencies of the bass hits)?
Thanks for putting up with my ramblings!
