    well if you have a three way speaker system, then its not really a subwoofer. its a woofer, midrange, and tweeter system. if they are all in the same box, they should have their own internal crossover, so you just need one amp to power it. do you have one or two? you could just even use a mono single channel amp, but they are way overkill at 500+ watts for subwoofers.

    just get yourself the bottom of the line car stereo amplifier. good brands are sony, alpine, pioneer. you can get a decent 50 X 50 watt amp for well under $100. I would also recmmend ebay. You can find extremely cheap car stereo atuff on ebay, just make sure its NEW IN BOX before buying...

    You are referring to an Op-Amp.

    Here is a tutorial on op-amps:

    Here is a list of op-amps for sale:

    a Google search will yeild more results for you. Op amps are not really desireable in car audio. I suggest E-Bay search "Cadence Amplifiers". They are excellent quality and a few sellers sell them very cheap on e-bay.
