first of all, I went through **** trying to decide what box for my 2004 dually. I didn’t want to pull the trigger on this, but finally did. And man, there is no doubt you will be the loudest underseat enclosure in your area if you RUN THE PROPER SUBS in it. Just a **** of a box. At first I had two P3s, it was perfect, but P3s don’t like lows. So I ordered the SA Classic 12s and 2000w amp because that’s what they sell these with. The thrash. Only 2 downsides to this box:
1.) you are not going to hit 25hz in this enclosure no matter what subs you’re running. It’s a daily driving UNDER SEAT enclosure. It honestly digs low better than it should. But with 99% of mainstream heavy bass, youll be super loud.
2.) with the SA Classic 12s, I’m not fully convinced they don’t hit the seats at full tilt. Seats are raised, no wires under the box. Installed to a T. But it definitely sounds like they hit the seats at higher volumes which kind of sucks.
Bottom line, just buy the box.
