Re: the weather is getting to me
well amp - amplifier boost up the Power (watts) coming out from your audio system. So for example, if your maximum power output is 120 watts and you have 600 watts amp, the output will be more powerfull. Tweeters are the opposite of subwoofers. Just like subs are used to play bass, tweeter plays those high frequency sounds such as you hear from strings instruments. But yeah you dont have to spend into all these, a nice set of speakers can change the quality. Pioneer is not bad either.
