I just ordered an Fi SP4 for my 2012 Impala. On my last set up which was a couple years ago, I just used a store bought box, which worked for all intents and purposes, but I want to go the proper route this time. I would be doing my sub a severe injustice by not giving it the correct enclosure.
A few questions: How do I decide what to tune it to? If I take a design to a shop will they build it for me? 3-5 cubes is the recommended volume from Fi, how do I know what should work best?
