ehckz Posted March 20, 2012 Report Share Posted March 20, 2012 I put my 2nd lvl 4 in last the other day, subs are D1s so they are wired to 1ohm (Amp is obv. 1 ohm stable (apk2500)) It will play fine full tilt as long as I want it to if the gain is less than half way however, the gain needs to be more than halfway and when I turn it up passed halfway the subs will play for anywhere from 30secs to 3mins depending on the song I guess and then the amp will just go into protect. The amp is not hot at all when it does this. Could this be a ground wire problem? I thought thats what it was originally and Ive put it in different spots and even changed locations. Could it be the stock HU is clipping hard or all the voltage out only at high volumes? Really have no idea what the problem is at this point. Speaker wires are soldered together. Amp is not touching metal. im lost. BUT WHEN IT WORKS OMFG IT SLAMS.

Real96SS Posted March 20, 2012 Report Share Posted March 20, 2012 So is the said amp setup with the DD-1 or an O-Scope? If not how do you know that it needs to be past the halfway point?Also are you using a bass boost on the amp?

pa-pa-platypus Posted March 20, 2012 Report Share Posted March 20, 2012 why does it NEED to be up past half way? Quote This isn't teeball. YOU DO NOT GET A TROPHY JUST BECAUSE YOU SHOW UP.

HatersGonnaHate Posted March 20, 2012 Report Share Posted March 20, 2012 Do you have any idea what the voltage is looking like at full tilt? What it's dropping to?

ehckz Posted March 20, 2012 Author Report Share Posted March 20, 2012 One can assume gain needs to be up because it is a stock hu with prolly like 1v out or something lol. Also the subs are wanting more power. Voltage stays above 13.5 at idle.

HatersGonnaHate Posted March 20, 2012 Report Share Posted March 20, 2012 Do you have a voltage indicator? Or were you checking voltage with a DMM on the battery? My guess is that it's dropping below 12v at full tilt, and throwing itself into protect.

My guess is that it's dropping below 12v at full tilt, and throwing itself into protect. Stinger voltage meter. I put it on the front batt also and it was about the same. I highly doubt im getting that much voltage drop because my lights dim around 12.6-13 when the car is running and they are not dimming yet. elec is stock alt and a hc2400 in back Quote Build In Progress for Slamology 2013 3 m1xl 18s walled in a gti 1 5k 4 batts audio technix 1/0 8 cheap r/f 6.5s mb quart 4.60 Link to comment Share on other sites More sharing options...
ehckz Posted March 20, 2012 Author Report Share Posted March 20, 2012 Tomorrow after work Im going to get it setup with an oscope and get it metered. Hopefully it just needs to be setup properly. Curious to see meter results though, getting violent flex.
