Well, you could go down to the Walmart Supercenter and pick up a 12" sub and a 12" box and a Amp. Of course this is the easy and cheap way to do it. The amp will cost the most talking $100 to $300 depends on what you get.

I really can't spend that much. I know I can get a sub speaker for 20 to 40 bucks... Ive seen cheep amps.... and I can build a box but,,,,, I dont understand dimentions and stuff like that. I want to put it in my trunk and port it to the inside of my car.

any ideas for me?

First thing, know what you want. Are you looking for quality, or loud? The easiest sub box almost anyone can make is a sealed cube. So you need to know what the recommended size for the enclosure is, this will be highlighted in the subs specifications. Most 10" are .5 cubic feet to .8 cubic feet. so now some basic dimensions you can start off with a 12"X12"X12" this is 1 cubic foot. Now it isn't bad to have more space in a box than you need, but it still needs to fit in a given space. To calculate cubic feet you take the inches in this case 12" for all three basic dimensions(Width, Height, and Depth) and mulitply them together. Whe you do this you'll get 1728 inches cubed. Now you'd have to divided by 12 three times to get cubic feet. But we know it's one since we already multiplied by 12 three times. This is a basic box that will be okay with any sub you've described. If you want different dimensions mulitply the three dimensions together in inches and divide by the 1728 and this will give you cubic feet. Remember this is going to be your inside dimensions. Have any odd shapes you want to build or more questions ask. Hope this helps.
