And these could fit in a box so that I wouldn't lose any leg room?
What is a good (but cheap) amp I could get that could power these?
Sorry, I'm a newbie at this and I have lots of questions!
1.) That is something you have to determine based on the amount of space you have behind your seats. I've seen many single cab rangers get away with single 10's and even single 12's barely losing any legroom...a silverado is bigger than a ranger but I'm not quite sure how many cubic feet you are looking at...before you buy a sub (or subs) I'd measure behind your seats with you seat positioned like how you would drive, subtract the space taken up by the mdf, subtract the bracing that would be inside the box (estimate), subtract space that would probably be taken up by the sub (subs)(usually around 0.15+^3 for a decent 12), then with that start matching up what subs fit the space you have. It is a hell of a lot of math and preplanning but if you do it right once then you will never have to do it again...DON'T RUSH. Also take into consideration that if you use multiple subs you might want to chamber them (give each sub it's own sectioned off airspace) so if one sub dies you don't damage the remaining subs...chambering off subs will requre more MDF and offer you less airspace but will give you more peace of mind and safety for your investment.
Here is a good topic about a guy that installed a 12" sub into his regular cab ranger...his truck is smaller than yours so you might be able to fit more but it will give you an idea of what is needed...

2.) A good amp for you situation really depends on what sub you plan to go with. There are several good companies that can offer you what you need...some of them are:
Phoenix Gold
Hifonics
JL
Memphis
Sony (J/K... //content.invisioncic.com/y282845/emoticons/wacky.gif.cf4a48f9e6dfe9504ffd2c946fd2f340.gif )
If you go with a single ten w/ 4ohm DVC, a single 12 w/ 4ohm DVC, or 4 8's with 4ohm DVC than I'd go with the 16-MC500D from Memphis. It puts out 500watts at 2ohms...it might not give you an earth rattling blow you ears out of you ass sound but it's fairly cheap ($200), **** reliable, and enough to push most of what you'll throw at it. Check out
ebay for cheap prices or go to a Memphis retail store and pay a lot of $$$$$$.
When you hear someone mention a brand that looks good I'd do a search on this board, read some reviews, and check out the prices on an amp that would match up to your subs...
I'll help you out some more if you find out your available airspace behind your seats...so get measuring!
