What Fordman said... +++
Stock head unit is garbage, and that goes for any preinstalled unit, in any car. They don't have the same amplifiers, etc. But, the manufacturers get you in deep because they build function into the head units... But for an older car, it's a no brainer! Bose speakers have paper cones, etc., and the amp doesn't have the power or signal to noise ration an aftermarket would have.
Get a head unit that has all the bells and whistles, ie, BT, GPS, Android OS, etc.
get separates for up front, silk dome tweeters, crossovers
get a decent set for rear deck
get a 4 channel amp, or 4+1 and a small sub, no need for anything crazy
you can thank us later...
I installed:
Pioneer DEH-80PRS
Infinity Kappa 693i
Boston Acoustic SR50's
Kicker IX500.4 Amp
4/0 wire kit for amp
#12 speaker wire
No need for sub actually, does just enough with Infinity's to not need it, but amp driven, head unit wouldn't be able to keep up although it sounded fine with Pioneer and amp disabled. And "Sound" is relative, these cars I felt are pretty good acoustically, and I like my music, so have no problem investing a little. By the way, the newer head units like mine, even though it's older now, take SD cards, I have my entire music collection on there, is awesome!
