Hi im wondering what the perfect dimensions for my infinity 12.1 perfects would be. They are being powered by a 800watt rms audiobahn amp. I have read many posts on the ported/ sealed argument but im still undecided for my subs. They are currently in a sealed enclosure with about 1 cubic foot each sub. If someone had a step by step diagram with dimensions I would greaty appreciate it. Thanks for your help
