[QUOTE="4bannger, post: 8266096, member: 646021"] Okay so I've post about boxes before to ask questions. A member here helped me with a 4th order box for my SUV. I followed his instructions the best as I could and just took his word for it because he seemed he knew what he was doing. After talking to a few guys that own shops around my area they almost looked at me when I was stupid when I told them how it was build. Even after going on another forum and talking to a few members they told me I went totally wrong Subs: 15" alpine type r Box: 4th order Box size: 47" wide x 37" deep x 24" high Ratio: 8 cuft sealed, 8 cuft ported Tuning: 40hz From what I was told the box is all wrong. I want to go with a ported box what should I do to make it have the best output. I was thinking about 8cuft after displacement 34hz tuning with about 14 sq in of port per cube. Let me know what your thoughts are. [/QUOTE]
