I tried looking in the How-to Stickies but every link I click on brings me to a different page for 4th and 5th generation models... dont know whats up with that. Anyway I'm just tryin to find out what is the model speakers for base audio units in our systems.... its clarion speakers but which model do I need to replace a busted speaker in the back?

-or-

what would be some nice speaker/subwoofer only upgrades could I do to enhance the sound without having to get a whole new aftermarket unit?

any help is appreciated...
