gckless Posted October 4, 2014 Author Report Share Posted October 4, 2014 So, just to go over things: DC 5.0k, wired to .7ohms. Set gain with sub level at 0 on HU, -2 is where I believe I'm safe right now, that's where I don't smell coil. These tests were done with one of the songs that the sub's been getting hot/stinky with, that main note is somewhere in the mid 30's. I set the DMM to max hold, but the clamp meter didn't have that feature, so I'll just take the max I seen on the clamp meter to give the benefit of the doubt here. Not super accurate, but it will give the max possible wattage I could have seen at any one time. Test 1 - Sub level at -2 on HU https://www.youtube.com/watch?v=fBdSH92FIgM&list=UUjdY_itePDSpaV-eC_KmL8A VAC - 53.9V Amps - 33.2A Watts - 1789W Impedance - 1.6ohms Test 2 - Sub level at -1 on HU https://www.youtube.com/watch?v=FhAxuspt1Wo&list=UUjdY_itePDSpaV-eC_KmL8A VAC - 61.1V Amps - 37.5A Watts - 2291W Impedance - 1.6ohms Test 3 - Sub level at 0 on HU. https://www.youtube.com/watch?v=8cFAUlkzD8E&list=UUjdY_itePDSpaV-eC_KmL8A VAC - 67.7V Amps - 41A Watts - 2775W Impedance - 1.6ohms All I did were these three, played it literally about 15-20 seconds longer, and I smelled coil and the cap was warm. Thoughts? "Clipping" is the biggest forum boner now. It's like witchcraft... it automatically explains just about everything people don't understand.

RossGo Posted October 4, 2014 Report Share Posted October 4, 2014 I know you have volt meters, but have you checked voltage at the amp inputs with a DMM while doing similar tests?I doubt that is the case, but you are on the low side on battery reserve for 5k, regardless of the 270xp. Would also put the "electrical" blame to rest, for yourself and the internetters Yes I have a lot of stereo weight.

gckless Posted October 4, 2014 Author Report Share Posted October 4, 2014 checked your batteries individually? I have not. I know you have volt meters, but have you checked voltage at the amp inputs with a DMM while doing similar tests? I doubt that is the case, but you are on the low side on battery reserve for 5k, regardless of the 270xp. Would also put the "electrical" blame to rest, for yourself and the internetters So here's my logic: if there's something wrong with my electrical, if there's not enough supply, I will see clipping in the output. Right? Like, that's the whole problem with not enough electrical? Supply and/or voltage will affect output, but you would see that on a scope. I may not be getting the full output I can get out of the amp, but what I'm getting is clean. Am I wrong? "Clipping" is the biggest forum boner now.

Blockburner Posted October 4, 2014 Report Share Posted October 4, 2014 I would think that less causes more heat build up than clipping. Clipping generally comes from over doing it. Or am I wrong...Is your amp getting hot as well? Team Deadly Hertz Ampere Audio/SHCA/Singer/ XS POWER Link to comment Share on other sites More sharing options...

REH Posted October 4, 2014 Report Share Posted October 4, 2014 Electrical doesn't seem to be the issue here at all, even if he has what some are saying to be the low side of the battery reserve... That woofer is getting a clean signal. Not to mention, he said he has a 270 alt, and 3 batteries and he's not having issues after playing hours at a time draining down, he has had them near instantly... And, he was having the problems when he's clamping 1.7k watts which he has well more than enough electrical for. Everybody always talks about this famous Tantric smell... So you're more than likely having that happening and freaking you out (justifiably) or there is actually some issues with the woofer itself being it is a fresh build and you're having problems from the start.

RossGo Posted October 4, 2014 Report Share Posted October 4, 2014 I'm not positive how well your O-scope shows the detail of clipping A DMM is an easy second check to cancel that idea out. Is your amp getting warm or hot at all? Yes I have a lot of stereo weight.

gckless Posted October 4, 2014 Author Report Share Posted October 4, 2014 Amp isn't getting any warmer than it did on the last setup. I really don't think electrical is the issue at this point.

RossGo Posted October 4, 2014 Report Share Posted October 4, 2014 I would agreeIf you were clipping, the amp would also be getting warm quickly, right? Yes I have a lot of stereo weight.
