DodgerCannon Posted August 24, 2011 Report Share Posted August 24, 2011 I've got this problem, Sounded like coil scrape... so took the dust cal off and have a look... it looks as if the former had slightly bent which was scraping on the pole piece. Seems to go for a bit after a good pound but gets so annoying on low volume... tbh when its really low that sub stops moving all together and the other carrys on. Any one know what causes this? Also that sub one of the coils reads 1.4ohm not 0.7ohm. Quote Link to comment Share on other sites More sharing options...
carlosg_313 Posted August 24, 2011 Report Share Posted August 24, 2011 or it can be the spider slapping the basket. had that happen to me before. just reglued it, and problem solved with goop adhesive. hope thats the bad part instead of something going on with the coil itself.

They said it makes your junk shrink all up. lol.im pretty sure the op wont even notice if it gets even smaller.

ChevyBoy95 Posted August 24, 2011 Author Report Share Posted August 24, 2011 (edited) Definitely not the spider slapping in my case(does it on like 1mm of xmax). I tested a little this morning, it seems to only do it when listening to the radio. Maybe the antenna is slightly loose And it more like a short quiet growl, but it isn't consistent, it does it randomly from every 5-10 seconds(seems like only when playing radio, I have yet to hear it when using my USB).

ChevyBoy95 Posted August 25, 2011 Author Report Share Posted August 25, 2011 (edited) bump added video in first post. 95% sure it is an air leak around the dustcap.

ChevyBoy95 Posted August 26, 2011 Author Report Share Posted August 26, 2011 its on its way to rusty. i was on the phone with him troubleshooting for 20 min. the coil former has a ridge in it. but when he gets it he will figure out what it is 100% Quote Best Score to Date : 160.5 dB Outlaw (47Hz)[4 XM 15's & 2 Taramps Bass 12k's] BL : http://www.stevemeadedesigns.com/board/topic/147800-chevyboy95s-4-15s-7krms-wall-1533-db-on-half-power/YouTube: http://www.youtube.com/hitemwiththeflex/ Link to comment Share on other sites More sharing options...
cc_audio Posted August 26, 2011 Report Share Posted August 26, 2011 (edited) Pull the sub and take a look. If none of the spiders are torn free air it on low power. If its coil rub it will be very obvious when you take it out of the box and listen. If there's no noise free air, then check your box for cracks or leaks. If your box looks to be solid, then it may be an amp signal issue. Edited August 26, 2011 by cc_audio Quote It's all gone! The Celica Build Feedback If I buy something from you, DO NOT USE FEDEX!
