What do I need to install 2 subwoofers into my car?

Okay obviously I need the Subwoofer speakers! I was thinking Kenwood. Perhaps something like this. http://www.ebay.co.uk/itm/KENWOOD-KFC-W112S-12-12-INCH-800-WATT-CAR-SUBWOOFER-/160641078562?pt=UK_In_Car_Technology&hash=item2566f45522#ht_1123wt_698 Then there is the amp. I was going to get a 1800W Kenwood Amp, or perhaps a bit less. http://www.ebay.co.uk/itm/Kenwood-KAC-9105D-High-Performance1800W-Mono-Car-Power-Amplifier-1-Channel-Amp-/250891823033?pt=UK_In_Car_Technology&hash=item3a6a5167b9#ht_2202wt_1178 When I have these things is there anything else I need to install the speakers?? Is the amp right for the speakers?
Answer:

this amp is a lot more than your subs need, your sub require 200 watt rms at most per sub with each sub having a 4 ohm impedance, typical scenario you will wire them in parallel to get a 2 ohm load, and get an amp that produces 350- 400 watt rms @ 2ohm. i guess you wanna stick with kenwood for the amp, the kenwood kac-8105d will save you some cash, just be carefull when setting the gains, because this amp is said to output 500 watt rms @ 2 ohm. and what else you will need. a sub box/enclosure, and 4 gauge wiring
