It is very tough to get the type of boom that some people want in our cars because of the body style, shape, curves, and size. Not to mention the back seat doesnt fold down. The best advice that I can give you is at the least, sound deaden the entire car. I know that it may be unefficient financially but it would help a ton! at the least, do the trunk. I also highly recommend making a box that is driver specific to the manufacturers specs. Ported boxes offer a higher amount of output than a sealed one but a sealed one is more "musically accurate". There is a company called Audio enhancers that make ported boxes speciffically for certain subs. You should check out their website to see if they have one for your sub. On the deep end, I would say that you would have a better sub output with a high powered sub like a DC sound lab level 4 15 instead of for example two infinity kappa 12'*. Now this is not to say that the infinity subs wont sound good because I think with the right box, they would. I am just saying that I higher quality sub in the right box with the right amp could potentially offer you a higher output. I hope this helps you. Let me know if you have anymore questions
