Hey all, I am new to the forums and was wondering if I could get some insight as far as sub choice and enclosure size. I Have a 99 Mustang GT and plan on building a system soon. I am torn between the SR104 DVC and the SR124 DVC. I have a Boston Acoustics amp that puts out 800 watts RMS at 2 ohms, so power is not an issue. However, I hear that the only difference between the 10 and 12 is volume due to the increase in cone size. I listen to hard rock and metal, mainly Disturbed, Metallica, Pantera, etc. I need the sub to keep up with the fast kick drum lines. Will the 12 be able to do this? Or should I stick with the 10? If the 12 will work, I found a box on Crutchfield's site that is 1.27 cubes sealed. Will this suffice for the enclosure? I know this is a lot of info, but any help will be appreciated.
