Thats exactly right. Your friend knows what he is doing.well thats what my friend said to do. turn your gains all the way up and then play music and turn them down until crackling goes away.
Depends on what volume it sees after all displacements. If anything, it'll be too small.is 2.8 cuft before displacement too big for a single fi ssd 12" powered by 1000 rms amp?
Perfectly normal.apparently the displacement of the sub is .14 cuft......that seems kinda little...
