Looking at installing a system in the 87 and figured this was a good place to get some info, looking at replacing the radio with a pioneer deh-p47dh ( don't want to butcher up the dash) a friend recomended pioneer 6x9 4 ways for the rearend, I am up for suggestions on the dash and door panel even the rear, wanting to keep the car interior stock looking, but sounding better, thinking about a amp later on down the road (maybe), give me some ideas. Thanks Jr.
