    Subs forward, upfiring ports (Sketch mock)

    Now this is my 2nd time using Google Sketch, and just playing around with it i figured out the basics, I didn't paint or nothing since I'm just trying to see if this is how to do a sub forward/upfiring ports, please help me, I want to build the box right the first time, and I know I should have gotten .75 mdf, but I got .5 by mistake, so I'll be putting another layer on top of each to make sure its durable. I don't have enough space nor money to just buy another sheet of .75 mdf, it's cheap, but I'm barely under my budget and I still got speaker wire, amp wires to buy for about 50$. buying another sheet would put me at 20$ for the wires. Anyways this is what I think it should be when it comes to the forward sub/upfire ports.

    and when someone does finally decided to help me out here, would this be better in a single cab or would side firing ports be better?

    Looks good side port may be a little louder but depends on truck so just go with what you have. What subs box size and tuning will it be

    Re: Subs forward, upfiring ports (Sketch mock)

    can it fire out the side of the box with no damages to to subs? so forward subs facing the passenger side, and port firing at the driver side window?
