wmrcs Posted April 12, 2012 Report Posted April 12, 2012 (edited) My HDC3 18 is making a noise that I can't quite describe, but I will do my best. It sounds almost like it's clipping, like a hollow type coily noise...it happens even at low volumes and I'm 100% nothing is clipping because my voltage is good, and tested the HU and amp with an o-scope.. Monday I will get around to checking the coils and seeing what they read, but is it possible that since my cut out is a hair too small that it could be stressing the basket or something and causing the sub to not excurt perfectly? Because I just had the sub inverted and I didn't hear the noise....Maybe Nikitaaa can get in here and help me describe the noise since he heard it today.

SnowDrifter Posted April 12, 2012 Report Posted April 12, 2012 Mine does that when I open the back hatch and the port has nothing to load up on.

Nikitaaa Posted April 12, 2012 Report Posted April 12, 2012 It's like a really odd mechanic grinding sound. His gains and ssf and everything is good. I just don't know why it could be..

If it fixes it I will be super happy. I honestly doubt moving it 3inches back is going to take that weird sound away. The sounds is like roof flex, only coming from the sub.. I just find it hard to belive that you messed up that sub from only 1200 watts not including box rise ect.. Take a volt meter to the coils. That would be the first thing I would do.
