Ok so I just purchased a new Mazda 3 hatchback and want to out in a woofer or 2. I have about $300 which I know isnt much but should get a some decent gear. $300 includes Speakers, Amp, and Enclosure. I'v been looking into getting maybe 2x10's or 1x12. If someone could possibly reccomend me a setup that would be great because I'm really confused about the amps such as the 1,2,3 and multiple channels how all this works.
