Scotnemily Posted February 12, 2020 Author Report Share Posted February 12, 2020 Crap you are right. I forgot to account for clearance around the port and the car. I will also move it off center just to be safe. Ill have to make the box narrower and taller to account for the port clearance. thanks for reminding me of that.

Scotnemily Posted February 12, 2020 Author Report Share Posted February 12, 2020 Maybe 2k not sure. maybe more. wouldn't it be closer to 28.26" for the 6" port? and be about 10 ^2 per cubic ft? I thought that would be enough... maybe not though. that's why I am asking Link to comment Share on other sites More sharing options...

ehall8702 Posted February 12, 2020 Report Share Posted February 12, 2020 Says for 2k in 3 cubes @35hz optimal is 66in2 or 22.1per cube.

Scotnemily Posted February 12, 2020 Author Report Share Posted February 12, 2020 Ok here is a revised box. I will have to loo at that port again. Link to comment Share on other sites More sharing options...
Scotnemily Posted February 12, 2020 Author Report Share Posted February 12, 2020 Also I wanted to add this last box was just going to be a quick test box just to put them in something. It could be a smaller sealed box, I just thought I would try to add a 6" port since I have plenty of 6" PVC laying around. It wont be the final version I will end up using. I just wanted to put them in something. Maybe it is a waste of time building a quick temp box... Link to comment Share on other sites More sharing options...
ehall8702 Posted February 12, 2020 Report Share Posted February 12, 2020 I like slot ports just because I don't have to buy anything extra to port and it helps structurally too. I'm guessing you can't get enuff port area with a 6" tube? It's just plain ass hard to get numbers right in small boxes with high power lol...and they quality u build boxes ( looking at ur last one for the xrs) u can build a temp box and sell it when u build the one you want ya know? 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears.

ehall8702 Posted February 12, 2020 Report Share Posted February 12, 2020 Also sonotube is cheap and you can get 8 and 10" pretty easily too if that helps any. Just gotta touch and glue it to two walls or some power will tear it up lol 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears.

Scotnemily Posted February 12, 2020 Author Report Share Posted February 12, 2020 Yeah I have the pvc so I was going to use it. I could do a slot port but it would take longer. plus I wasn't getting the sr inches I wanted there either. If I need more than one 6" port it becomes longer than my box. an 8" is also longer than the box. so right now it is probably a single 6" or no port for the test box. I would like to try using a PR or 2 like that earthquake one (not sure if it is any good though) but I don't know how many I need. I think I understand the tuning method, just afraid two 10" isn't enough for quad 8" subs. Also I would have to buy them. everything else I have laying around....
