Need some advise from the CA.com community. I'm starting to think my car peaks to high to put up any kind of numbers with a daily box. I'm happy with the box I'm using now for daily but I need more then a 145 to win a real show, I do fine local in class. Normally take the win by more then 5 dbs which is sad. Gear is two XL m2 12s on a 5K. Right now the 145 is tuned at 31 hz peaking at 46, at 35 hz it peaked at 50hz hitting a 147. What do I need to tune to to break that 50 db mark or more, I dont have a problem swithing boxes since I cant to changable ports? I cant do a 8 inch areo so it will be a slot down the middle firing back, subs up. With no bends I can get a 46hz tune or higher. I'm not trying to do a complete one note wonder, just want to do a good number when I need to.
