[QUOTE="Zeroflex, post: 8715342, member: 680832"] Hey guys and girls. I'm having an issue with a burp box I've just build. I have the plans given to me by a freind know has made a few diffrent style burp boxes but for some reason this is not hitting what I thought it would. My aim is 155's on 5k in a minivan/wagon setup. My system is: 1 x ZeroFlex 5k 2 x ZeroFlex EVO 15's 3 x 100ah lithums 1 x 500farad cap bank I've attached the spec my mate gave me and pix of the box, the port is 11" round x 13" long internal. I am thinking of going 45's internal and changing the port to a horn style starting at 9 1/2" internal Caming out to a 11" external at 8" out side the box. Currently only managing to get 149.8 at 46hz out of it sealed on dash which is way off where I'm aming for. Cars resident frequency is 56hz. Any help would be greatly appreciated thanks [/QUOTE]
