On CD decks, like at bestbuy or circuit city, on the card there are numbers like:

50 x 4 watts


The guy said to match up wattage with wattage on speakers, but all the speakers are like 200 watts, and not 50 x 4 watts. What does this 50x4 mean?

Also, what are preouts? I see some decks have 2 and some have 3, which is better?


And with satellite radio, when I get either an XM or sirius they come with car kits, so is that everything I need right there, to start listening to it in the car? a couple of the radios I was looking at came with something called a secure direct cord or something like that. where would that plug into?
