Burp box...

[shredder1 10+ year member]

You're going to be tuned around 40hz when this is done I suspect. Give it a whirl with some old school rap (NWA, 2 live crew) or some Sabbath or pre-haircut Metallica and see how you like it.

This won't be for music... is Winisd/Torres off... this said 46 hz and was really peaky right at 50 hz?... I suppose I could trim the 90 off... don't scare me like that... it's supposed to be for burps... 40 will be an improvement but far from ideal...

Your truck might peak from 49-51 with port back. Same car can sometimes peak 1 or 2hz different just cause of something random like a weak spot weld from factory. I havent experienced it yet, but ive also seen people who vary 1 or 2 based on power input.

One thing ive noticed in my truck with every box, kick likes 2-3hz lower than glass

thats why I said just make a square removable port. A burp box will need all the flexibility you can afford. Go a little bit bigger than shrink for both box and port.

Take a look at the port configuration...

Should I leave it as it is... or should I just run it back till it's a port width from the rear wall?.. This configuration might change tuning as it is I'm told by "seeing" extra length from loading off the back wall... I hope I'm quoting Hispls correctly...

I'm not able to make a removable one so I can cut the bend off clean and add one later if need be... thoughts?.. and I'm losing the 45's except in the corner behind the port.

yeah in my buddy's wall my back gets extremely itchy after every 50hz demo like a skin rash/irritation. His meters less than mines but felt louder. I could only imagine if he actually built around 50hz burps rather than low notes.
