x2, go ahead and get the SSA 15" XCON and Sundown SAZ-1500D combo at the store.

XCON 15" sealed in as much space as you can give it. With about 1500w.

you could try finding two kenwood excelon x10d's wire it series parallel for 2 subs in a 2 ohm load. there rated at 600 rms but only put out about 400 rms at two ohm this is one that come to mind that is a class d and they sell for about 150 -170 on ebay.com ikesound.com and amazon.com. your just not going to find any high end for $ 300 to push 4 subs

TireRack has the Eibach kit for the Marauder for $129. Should work for you.

My advice is to not buy something that you'll have to sell at a loss later. Perhaps if you want two subs in the future, just buy one now, and the amp for it. For example, you could buy an Icon and a sundown SAZ1000D or something, then when you get additional funds you can add another Icon and another 1000D and daisy chain them. Or if you want FI BLs, maybe you could buy one now and a small 2-channel amp to fit under your budget. Then when you get more funds, buy another BL, buy a bigger amp, and switch the smaller 2 channel over to powering your front speakers.
