Hello I have a 2000 ford f150 ext.cab. I have a 12" sundown audio sa12d4 and a kicker zx1500.1. I have about 15"W X 15"D X 24"H. I'm wanting to build a sub box but not quit sure which one works best for me. People have told me the only one I can do is a down fire ported box with port facing eighter driver door or passenger door. Sub will be behind driver seat. Any input will be appreciated thanks.
