What type of subwoofer to choose

Never owned a car with a custom sound system. Recently bought a car which has a prewired (working) amplifier Alpine mrp-mp350 700w in a trunk. It is wired to the stock audio head unit with a seperate switch to turn on/off. And a cable hanging for a subwoofer +/-. So Instead of taking it out, decided maybe buy a subwoofer but have no knowlege how powerful sub I can connect to it. Can somebody recommend something for the first time buyer/user?
 
How much space are you willing to give up for the subwoofer enclosure? What is the vehicle?
Hey, I was thinking just a single, already boxed 12" sub. I don't know/understand how good and powerful my amp is. Or if it is possible, maybe 15"? Does size matter in this case? My car is a vw passat b7 sedan/saloon.

I think something like this. Will my amp have enough power for this?

Your amp will power it, but not to the speaker's full potential. I personally will never used a sealed box again, because ported gives you double the output (according to my ear-meters). Again, suggestions depend on space available. A better enclosure is preferable to a better speaker.
 
Alpine Type S or Type R in a ported box.
They both seem to be very powerful. The main question here was, to find something reasonable for my amp to be able to play it. I cheked some forums and I don't know of I understood it right, but looking at my amps specs I have to look for subwoofer with max rms at 350w 4ohms.

Max 350 rms sub means that your amp should be around 700 rms. Just sayin.

Please, explain. I don't understand anything about this. My amp is MRP-MP350 700w, can someone check the specs and tell me what to look at when I look for subwoofer. Max rms, ohms, max power? No need to name manufacturer, cause lot of the previous subs not available where I live.
