Sold Custom Subwoofer Enclosures

you dont quite tune the box doesnt have dials lol amp tunes the subs and a simple measurement and little math will set your box calculations
They low boost switch is for "Bass Boost" and simply boosts the gain at the 40Hz frequency. This may seem excellent and may sound good at low levels but once you turn the volume up at the head unit "Bass Boost" is one of the main causes of distortion = bad.

The 12 - 24dB switch is called a filter slope, For your subs amp a low pass filter (LPF, which yours should be set at) is how fast the frequencies are attenuated above a certain frequency, usually around 80Hz. People have their preferences but I prefer setting at 24dB for a subwoofers LPF.

For the filter settings on your amps you could always experiment to find whats best for you but I find the setting the 4 channels HPF at 80Hz and the sub amps LPF at 80hz is a good starting point.

 
i would like to see that prefab box with the amp rack
I have no reason to lie to you. I purchased that exact box no less then 3 years ago. It was prefab box with no special treatment other then a sliding amp rack (which was decent, but no amps fit correctly) and it was wrapped with a plastic chrome with sticky back on it.

Nice copy and paste. Bro, learn how to tune a ported box, an amp DOES NOT tune a box, your wood does. Like 90% of people run ported, you need to know what you're doing.
