SnowDrifter Posted December 16, 2013 Report Share Posted December 16, 2013 I've been having this odd problem where no matter what have hooked up, there is this disproportionate amount of heat dumped into the coil. If I use my mixing board as a source, I can free air one of my 12s and the coil gets stinky in about 3-5 seconds at any volume. This isn't a bunch of power either. 400 watts. There is nothing obvious happening - no strange sounds, sub is moving equally in either direction, and my multi meter isn't picking up any sort of DC offset If I remove the mixing board and plug straight into my crossover (which then goes to the amp) I get results like what I would expect off of 400 watts. Coil stays cool enough to touch even after several minutes. I've tried playing a square wave straight into the amp, just to see if some sort of clipping may be the culprit and I can't seem to put much heat into the coil. It remains cool to the touch. The only conclusion I can draw is that there's something funky with the mixing board. But now I'm curious what in the world could cause this to happen? ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
Skullz Posted December 16, 2013 Report Share Posted December 16, 2013 I had a H/U that would randomly start clipping the signal to the sub, so you could replay a song and all of a sudden you begin to smell the coil from the clipping it was doing. i wound up replacing the h/u and have not had a problem since so i would at the least try another mixer to see if it is indeed that one causing the problems. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

SnowDrifter Posted December 16, 2013 Author Report Share Posted December 16, 2013 Yeah that's the piece of broken equipment... But I'm curious how it could dump that much heat into a coil without something obviously looking/sounding wrong. I mean... These subs were on a wall socket for 5 minutes and showed no signs of failure ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

RCP Audio Posted December 18, 2013 Report Share Posted December 18, 2013 I think everyone is forgeting snow posted in the pro audio section lolwhat desk is it pro? Ill have a look at the shimetics and see if there is anything that could possibly cause it, are the desk/crossover/amp all plugged into the same power outlet? PSN: Rcp_soundz Good rule of thump is go by what fuse size is being used in these amps. The higher the more amperage it pulls, this is what I look at. I'll stick a 300 amp fuse in a potato and sell it to you for $2k. 1991 Mazda 323VERY small build thread here: http://www.stevemead...23-small-build/ Link to comment Share on other sites More sharing options...
