Re: Amp classification
An amplifier does not omit sound. It's like a power generator. All speakers need an amplifier to work. A sub woofer is a speaker, that omits sounds, but in low frequency bass tones. Very different things. Most cars come standard with the speakers and amplifiers you need, but if you are wanting to increase the quality of the sound you may want to upgrade. Go to a place like "Car Toys" and ask them all the questions you have. They'll answer them and show you all the options. They have many amps, speakers, etc. so you can hear and see the differences for yourself.
