Got a 2009 Pontiac G6, base. Currently have 2 SQ HCD3s D1s on a sq 4500. I plan to get 2 more HDC3s and another sq 4500 and place em in a wall. I need some ideas on how to get loud and low. Meter and ear wise. Questions: What should I tune the box to? Where should the port be? Side or on top? How big would you build this box? Missing the measurement info, I know this. But throw some ideas out there for me..aero or slot ports? Electrical is good. 3 155ah Duracell Procells and a 270amp alt. So atm I am not worried about it. Ideal wise, I want to run 2 ohms for daily and .5ohm for burps.
