Guess ill use the newbie list to make this as clean as possible, 1.Subs, Six 10" series 187. 2. Vehicle, backseat of a 1996 ford mustang. 3. Amp, Audiopipe 3001.d 4. battery's, one kinetic 600, and one kinetic 2400 5. electrical, Alll 0 gauge, Big three. 6. had two fusion 15's ported at around 38hertz, sounded alright, wouldn't mind deeper lows. 7. im having a wall built for the backseat. a square common port in the center with three on top and three on the bottom. If anyone has any advice on what the box should be ported to, i was thinking around 33-35, my goal for getting all my systems was to be able to do a hairtrick, and since then have been unable to, so if anyone has any advice it will be greatly appreciated, please and thank you
