The box will be larger unfortunately.


True enough. Since the driver is an upgrade from PSI, I don't have the relavent specs to build a proper box. I built this sealed box according to intuition and it really rocks. It goes pretty low (sub 30hz with all that power) but the trade off seems to be the sound that I want or overloading my electrical system.

Sigh, I guess there is always an alternator upgrade and the big 3.

But I should stop while I'm ahead and not hijack the thread. I mainly wanted to point out that the MS-8 will shutoff (probably upon a detection in voltage drop).
