Aloha everyone

It got me thinking. Am I losing out on output? The soundqubed site says tune to 100-125hz. But I returned it today, I went down to 10oclock and

Turned the gain up past 12oclock. The gain flickers but not stays on. Idk what the deal with these amps is. Tomorrow I switch boxes to see if that sound persists. Because as 15zv3 was in there and I never heard the noise I'm hearing before. Sorry for multiple posts, phone acting up

The only other things I can think of if its not the amp, Is a standing wave in the box or the pvc port resonating.  Couldn't hurt to throw a brace in the center of the box. A lattice style brace will help if you are getting a standing wave in the enclosure due to its odd shape. Possibly the pvc port needs braced if its resonating. So If it was me I would try a different amp with that box, AND try that sub in a different box with your current amp to narrow down the culprit.

Ya I'm building a new box. I did include a brace in the middle, same size as the walls but hollowed out a bit. I don't have a different amp so I'm switching the box instead lol
