i was wondering what would be the best way to go about installing my 2 audiobahn subs to my new 05 accord (it's in the honda shop right now). i wanted to put a new stereo in it but i was wondering how i would go about doing that since the climate controls are a part of the unit

....what would be the best way to go about getting this done? (i've got 12 audiobahn subs and a amp that i had in my previous car)
and im thinking of getting some pioneer speakers to replace the factory ones...
anything will help, thanks
