When you compare costs of rebuilding the sub with the price of the M II it's not $1500. If your spending that much on the truck and taking a while to do it why put it together other than the way you really want it? One thing about sub's is they will usually ride better. I know that statement will draw someones rath. I have a sub on my cpe. and it rides and handles great. One concern is that it's the right width for the vehicle and that it's installed right and not half@#%.
