Welcome to the forum.
I think you would be disappointed in the coupe's Bose system. The bass module is between the right quarter panel and the cargo compartment wall. The bass module is not ported into the cabin. The standard speakers have the normal impedance. I think you need line level converters to hook up aftermarket amps, but I'm not sure. People's opinons of the stock speakers vary greatly.
An alterative you may wish to consider is the Becker Audio 10 head unit. It has a single cd player in place of the cassette deck. It has more powerful amps than the Alpine headunit. People who have installed the Audio 10 report much improved sound, especially bass. Most people buy theirs from German ebay, but you can get it for $649 from autoclass.net.
