What kind of setup will get my good loud speakers with deep loud booms?

I have a 99 jeep grand Cherokee Laredo and o want the thing to boom. What head unit amp and subs should I use? I already have the stock infinity system. Should I just replace with mire infinity or change to something else? Also please explain amp and subwoofer why you choose it. Also if you could explain ohms and explain everything. Single coil and double coil. Plus what would be a good overall system wattage to aim for? I want it to boom as loud as possible without making **** rattle ie doors windshield wipers. I want it to sound good nor cheap? Is All this possible with about 1k? For parts? Don't worry about installation. Thanks.
