Not only are the Bose 2 ohm speakers hard to match since all aftermarket are 4 ohms but everybody strongly believes that the Bose system will be severely miss tuned by adding aftermarket. For me it'* hard to believe that a speaker could cause any damage to the system but why is everybode else convinced it will?. I do want to retain my system but do not like the weak speaker set up.
I have JBL 6x9s in my SSEi and I think they performed better than the Bose that was in there. I chose the JBLs because they had a 92dB rating, the most efficient that I could find. Also, they were a 6x9+ design that had a larger cone than most 6x9s on the market. The price was nice too, $70 new from Crutchfied.
Alpine has a low dB rating, that is why you got 'double slammed' when you upgraded.
