Slawsen Posted July 31, 2010 Report Share Posted July 31, 2010 What can cause subs to be out of phase? Is it harmful? I have 4 SVC subs on a monoblock amp and they appear to be out of phase.

Team_DC-Derrick Posted July 31, 2010 Report Share Posted July 31, 2010 1 or 2 could be reversed... try switching the wires to see if it puts it in phase Quote The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall.......

cqtama Posted July 31, 2010 Report Share Posted July 31, 2010 (edited) more info on the setup would be helpful. what kind of box? but this ^ do they appear to be completely opposite of each other? an easy way to test if they actually are out of phase is to pan all of your music to either the right or left. then when you pan back to center it should be significantly louder.

All are wired correctly, setup is in my sig, but I'm not sure on the specs of the box. I can tell you that the design of the box sucks..i'll brb to talk more Quote 00' Nissan Xterra Always under construction :] HU: Pioneer DEH3100-UB Mids & Highs: Kicker DS Component Set & Crescendo tweeters Mids & Highs Amp: Rockford 150.2 Subwoofer: 2 DC Audio LV 4 18"s Subwoofer Amp: Hifonics Brutus 2005d you been hanging out with jeff and dustin with that green paint? its yellow so it has to be loud.

bobonit Posted July 31, 2010 Report Share Posted July 31, 2010 If you have a DMM (Digital Multimeter), you should check the DC Resistance of your coils to make sure they all read correctly.

I just wanted to know if it could hurt them..cuz its just slightly moving different. sounds good and its not moving opposite..just seems to me like its not perfectly in sync. I'll check them with the meter later. Off to work. Thanks for the help so far Quote 00' Nissan Xterra Always under construction :] HU: Pioneer DEH3100-UB Mids & Highs: Kicker DS Component Set & Crescendo tweeters Mids & Highs Amp: Rockford 150.2 Subwoofer: 2 DC Audio LV 4 18"s Subwoofer Amp: Hifonics Brutus 2005d you been hanging out with jeff and dustin with that green paint? its yellow so it has to be loud.
