I'm sorry but please don't give out false information. With the last 2 posts I can tell you shouldn't be giving this guy advice. You just gave him dimensions for a slot ported box when he asked for a t-line. Then you told him your box would be louder. How do you know it will be louder? Do you have the exact same vehicle, power, sub, electrical, and have tried a t-line compared to that box? Then you tell him he'll be doing mid 20's on the termlab? Really dude?
