Answers: All that stuff you mentioned is close to aftermarket stuff for car sterio.
There are subwoofers, which produce like mad of bass, which require an amplifier, the source of power to the sub. Vents are just so nouns can get contained by and out. Vented, or ported subs let nouns out but are not as crisp, closed subs arent as loud and are more crisp. Subs arent necessary, one and only for people who close to lots of boom-boom.
RMS is the term referring to how frequent watts the speaker or sub can produce. if you are looking for just speakers I would first check to see if your pave the way unit (or radio) is within good shape.
A polite head section will produce around 20 watts per channel, or 20 watts for respectively speaker. Anything above that is better.
Now regular speakers are pretty cheap, you can obtain no name stock replacements for $50, but if you want brand name, good brands for audio include MTX (mainly subs), Alpine, Kenwood, Sony, Infiniti, Bose, JBL, and JL Audio.
