How exactly does one know what setup to get. Where is a guide for this?
Specifically, I have heard that Kenwood and Pioneer are really good. Great, so I pick out the deck I want... now how do I know what speakers to get? Is there some formula I should look for? Like if over XX watts get ZZ type speaker?
Example, one deck that looked good was rated 100 watts X 4 chanel. Someone said that means it's 25 watts a channel, meaning my speaker need only handle 25 watts. But if the speakers are too big that's bad, and if the wattage is too low I need an Amp, so GAH! How do I know what to get!
Any suggestions? How can I listen to my iPod? Any good stereos?
