I know that box design is ultimately dependent on the user and the vehicle but I need some help choosing a starting point.
I am installing a FI-Q 12" in an '06 Grand Prix fed by an AP15001.D.
I'll probably build a slot port enclosure due to the ease of manufacture.
If I can give you any information that would help you guide me towards a decent first box for this car, let me know and I'll post it up.
I'm just looking for a general idea of where to start with enclosure size and tuning.
Edit: Just reading the manufactures recommendations and choosing a mid point I'd be around 2.15 ft^3 at 31 ish hertz.
