My plans for my truck changed and im tired of trying to get bass from under the seat boxes and since i cant do a wall im just gonna run a blow through. Its a 2004 dodge ram 1500, i want to run 4 12" subs in it if possible. Im gonna get someone on here to design it (paying of course) i just need to know what i should run as ive only used sealed boxes before. Should i be looking into getting a 4th order, or a ported box or what? I can get some dimesnsions as soon as i get off work if i need to.
