My car sounds great with factory deck and upgraded speakers, and the beauty is, no one will break in to steal a factory deck. This is something you need to consider being young and driving to school, the mall, parties, and I can almost assume parking outside at home because mom and dad's car is in the garage.

I guess I don't understand how underpowering speakers is bad for them. To me that is like putting a V-6 in a Corvette. You aren't going to break it.
