I spent some time at the audio shop today and figured out a system that I think is good for my car, but I am not 100% sure as I don't always trust the stuff the salesman tell me. So maybe you guys can give me a heads up if this is good stuff.

I am looking at a Panasonic head unit, some Infiniti component speakers, and MTX 5 channel amp and 10" sub. Good stuff?

Also, are Viper alarms any good?
