i know its a hard question to answer because of all the factors that go into it, but i have a 15" x.x.x in a 4ft^3 vented box, powered by a orion 1200D amp, in the back of a f150 ext cab truck. about how many db's you you guys think i could hit, and ish number lol. i dont have everything set up yet but i was just wondering.
it depends... are you looking to enter compettions or is this your everyday car... For everyday i say tune around 32hz. For compettion tune your sub around 50-60hz
