My parents had a 1986 Acura Legend and the Bose system in it was downright good. Even had an equalizer built in. I've always done my own vehicles aftermarket since and I gotta admit I'm pissed at what the auto industry has done. They charge $2,000 to $3,000 for the premium system with NAV, which Alpine, JL, and Rockford could kill for $1,200 or less.
I've driven a 1993 Lexus SC 400 for the last 12 years as a summer car, with aftermarket Boston Pros (speakers and sub) and an Alpine head unit and amp. I've been looking at getting a newer car and just laugh when the salesman starts to brag about the sound system in the newer car. 2 to 3 grand for that sound??? It's ok but nowhere near worth that much. What really angers me is now the radio, cd, and ipod controls are all stuck in the computer that runs the hvac and all the other controls. There is nowhere to put an aftermarket system. I wonder how much money all the aftermarket companies are losing due to the car manufacturers essentially building them out of their vehicles. I've found a few newer cars I really like (bmw 5 series, mercedes e class), but I hate to give up my great sounding system in my vehicle, and it has been a big reason I haven't moved up yet.
