View Full Version : Subs forward, upfiring ports (Sketch mock)

07-23-2012, 01:52 AM
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

07-23-2012, 05:50 PM
1.2 ft3 tuned at 34 hz

07-23-2012, 05:53 PM
either subs to the passenger side port to the drivers side .or better subs forward and port along the back side of the box under the rear window

ill do a mock up of the subs forward and port side, and you can tell me if its wrong, is it subs one side port other, or can the subs be on both sides?

I don't fvcking understand this, when I do calculations ***** is wayyyyyy off, a 4" aero port will be approx 36 inches!?!?! wth can someone please help me, I've tried for a week now and havent come up with a solid design for this box, dimensions are as follow

From door to door, 46", from floor to top 10.5" from bottom of seat to wall it's 7", from the top to wall it's 4 1/2 inches, I could do square or wedge, though wedge will be hard since I dont have a fvckin table saw anymore. CAN ANYBODY HELP ME!! I want my 8's to sound good, i dont care if it's sealed or vented, just want it to fit tuned right.

One 3" port 16" long fired out the passenger side......33hz.....with the dimensions you gave above.....I guessed sub displacement at .14 for both combined....

07-24-2012, 10:49 PM

double 07

07-24-2012, 11:05 PM
^^^^this..... flaring pvc is as easy as crisco oil, a hot plate, and some to mold the pvc lol... ive done this plenty of times

07-24-2012, 11:09 PM
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?

07-24-2012, 11:12 PM
and is this a square box or a wedge?

07-25-2012, 02:39 AM
So here is a mockup of what I got so far, please give me advice, subs too close to port, etc.
