Alright so I'm thinking about buying my parents 2000 4runner but I have a major dilemma.. I will (in the coming months) be getting three more hdc3 18 which will put me at 4.. I just want to know what the smallest total cubic feet I could have for a box (not a wall, a subwoofer firing upwards and port firing backwards box). Because if these don't fit, I'm gonna buy a bigger suv. I don't need box plans per say just general information like how close to the roof is too close and also how close to the rear hatch is too close for the square port that I plan to have rear firing.. Thanks for any help!
