Evan12 Posted June 8, 2014 Report Share Posted June 8, 2014 I just installed my sundown zv4 15 to my Hifonics 2000 amp down to 1 ohm. When I play my songs and turn it up the amp cuts out and the subwoofer bottoms out at a very low level. I'm not an idiot and turn the gain all the way up it's almost halfway up. I'm very confused on what could be wrong Link to comment Share on other sites More sharing options...
CleanSierra Posted June 8, 2014 Report Share Posted June 8, 2014 So your gain was set by ear then? I don't think that sub can be bottomed out very easily, you may be hearing noise from the enclosure itself? Who built it and who designed it? Pictures will help greatly, as well as setting the gain PROPERLY with a tool such as a DD-1 or oscilloscope. Im not the one you want to try to troll. Just a fyi for you.

Evan12 Posted June 8, 2014 Author Report Share Posted June 8, 2014 I built it myself. I've built many ported boxes and they all worked out good. Since I'm on my phone I can't add pictures. The dimesions are 19 tall 41 wide 17.5 deep The port is 3.25 wide and 20 inches long Link to comment Share on other sites More sharing options...
CleanSierra Posted June 8, 2014 Report Share Posted June 8, 2014 Without seeing the box, no way can I tell. Dimensions alone will not help in this situation. That subwoofer should be hard as shit to find a hard bottom. Not impossible, but seems unlikely to me. You can confirm that you set your gains by ear then, right? Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
slowfkncar Posted June 8, 2014 Report Share Posted June 8, 2014 Actually if im not mistaken, there is nothing obstructing the bottom of the coil from the back plate except the spider. You may "soft bottom" of too much power. And btw it took me 3500rms clamped to soft bottom a zv4 15 in 4 cubes. I did however have a faulty amp one time, at loud volumes the sub would suck in and play,not really a bottom out "didnt hear no clacking ect" it just sucked inwards like the suspension got forced back. Swapped the amp,problem solved. Do you hear any metal to metal clacking? Or is it like a turbulent rubber paper sound? Link to comment Share on other sites More sharing options...
CleanSierra Posted June 8, 2014 Report Share Posted June 8, 2014 With the amp cutting out, I'm gonna go with a bad or loose connection on the ground. The noise you hear from the sub is likely a side effect of the grounding issue. Im not the one you want to try to troll. Just a fyi for you.

CleanSierra Posted June 8, 2014 Report Share Posted June 8, 2014 You also didn't mention your coil configuration of your sub. Is it a D1 or D2? Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
Evan12 Posted June 8, 2014 Author Report Share Posted June 8, 2014 My sub is a d2 wired to 1 ohm. I'm going to try to reconnect the ground and see if that works Link to comment Share on other sites More sharing options...
TaylorFade Posted June 8, 2014 Report Share Posted June 8, 2014 You're clipping the fuck out of it. Plain and simple. Link to comment Share on other sites More sharing options...

I agree that pictures might help, although a video of the problem would work pretty good too. Thinking is the root of all problems... You ALWAYS get what you pay for.
