It really is a great car. Purchased it from a sweet old lady last week, it has traveled 10,000 miles in the past 10 years, 80,000 in the 10 before that. The original Becker stereo is fine but could use a little somthing. I was hoping to simply replace the speakers with new high quality ones of the same dimension. Will this not work? I was reading a previous post about coaxials and 4 ohms etc and that an amplifier would be needed. Sounds like I should just leave it alone until I want to replace the whole stereo. Then I imagine I would need to fish wires. I still just want to replace the speakers?
