crav1n Posted June 27, 2011 Report Share Posted June 27, 2011 Okay! so! I have my 4 sundown sa-15's, on an AQ 3500d. the problem I'm having is that once I get to around a certain volume, (the max I usually listen to it at) my amp protects. Also, once it starts to protect, it seems to do it more and more. 1) the amp isn't overly hot. 2) the head unit isn't at the clipped volume 3) my voltage isn't dropping below 13 one thing I'm thinking it may be, is a bad coil? I re wired everything today to check if maybe I messed something up on accident, but it is right. It SHOULD be wired at or near .5, but it is sitting at a solid 1 ohm. (all 4 subs wired together) When I tried wiring in 2 sets of 2 subs, each set of subs were sitting around 1.7 ohms, when they should be around 1. I know a little high or a little low is normal, but .7? I could be wrong, and I probably am but I don't think there is or should be much clipping going to the amp because like I said, my voltage isn't dropping hardly anything, and my HU volume isn't turned up to high. So I don't think it's protecting because of too much clipping? IDK! help! Quote Link to comment Share on other sites More sharing options...
irpirate Posted June 27, 2011 Report Share Posted June 27, 2011 kkk ive been tryin to help him but i'm kinda noobish at this stuff things i wanna add. subs are dual 4s. 8 gauge wiring from subs, directly to the amp. box used to be a flat wall, was just rebuilt to a 4th order. what i don't get if it was a bad coil why each sides reads around 1.7 with just 2 subs.

Pay no attention, they just want 89,000 watt subs for 3.50If you would have put a dc dustcap on it and called it lv your mom, they would all be in love Link to comment Share on other sites More sharing options...
crav1n Posted June 27, 2011 Author Report Share Posted June 27, 2011 a little background on my jeep: electrical - stock alt, 3 g31's in the back..2 deka 9a31's and a xs3100 3 runs of 0 gauge to the back all 8 gauge speaker wire before I rebuilt this wall from my flat wall, my subs wired perfectly to .5 and my voltage would drop no lower than 12 volts. now at IDLE I'm dropping maybe .1 - .2 volts tops and everything is wired the exact same. I don't get what is wrong. Quote Link to comment Share on other sites More sharing options...
lifted_silverado Posted June 27, 2011 Report Share Posted June 27, 2011 Im guessing somethin internal with the amp. Have you tested another sub on it?

TheyDontWantMusic Posted June 27, 2011 Report Share Posted June 27, 2011 most likely short circuit protection. your new box doesn't have as much impedance rise, so the amp is going into protect. Quote Link to comment Share on other sites More sharing options...

SpartanSound Posted June 27, 2011 Report Share Posted June 27, 2011 Not quite sure, but it may be a charging problem. This happened on my friends amp and if you have a low ohm load with only a stock alt then your problem might be lack of current to support it?? Not one hundred percent, but could have something to do with it. How long have you had this set up? Did it just start happening on you??

Not one hundred percent, but could have something to do with it. How long have you had this set up? Did it just start happening on you?? I've had the same setup for a while now...a bunch of different boxes. Ive had it occasionally protect from being stupid on the volume and it clipping too much, but I don't think that's the case here. and I wouldn't think that it would be a charging problem if I'm not dropping low in the first place?
