I'm definitely not an audiophile, as I spend the most time in my car driving around over lunch breaks, but is the factory amp decent enough? I know I've read enough about people saying to get rid of the Monsoon system, but I'm not really sure if that's geared towards the system as a whole or just specific pieces of it or how it's put together. I'm not actually sure what the specs are on the factory amp, to be honest.
