Also how do they work, are subs underneath?
Also do I need a "amp" and what are they
Answers: Try a bazooka powered sub. It includes an amp to power the 8 inch sub and will fit clearly behind the driver or passenger form of an Xtra cab.

for $200 ur out of luck, the best u can do for that much is a shitty system thats not worth the money, , and yes subs are strictly bass, and basically an amp powers the subs and processes the music so that it sends the correct signal to the speaker for whut ur setup is, very soon if u wanna go cheap win 2 12" sony exploids from walmart, 2 build a box kits, and they enjoy a sony exploid amp for $150, with everything it might run you $350-$400, but its cheapest u can get hold of while still sounding half opening decent, u also want an aftermarket radio, its alot easier to install urself if u hold one, oh i almost forgot, ull need a electrics kit as in good health, those are about $30, and usually they come next to instructions for instalation and a # u can call if u hold questions on the specific entity u have, if i be you id rescue up for a while and go to circuit city, it will cost more, but u can procure some thing really correct and installed, so its up to u, good luck
