adam6604 Posted July 6, 2011 Report Share Posted July 6, 2011 hey guys i have a question, its hard to explain but ill do my best. my 15's share a common chamber ported box, when im playing, the sub closest to the port moves no problems just like it should, but the sub farthest from the port hits in time as the other sub, but not nearly as hard. like for example when playing White girl-young jeezy, at those low notes, the sub closest to the port is moving like crazy, real good excursion ( for what im pushing ) and the other one isn't doing much at all, but when its a bass-kick? they hit at the same time.. so i dont think there out of phase.. local shop said it might be my box because its common chambered. any ideas?

One of my subs was flexing more than the other one and it was cause one of the voice coils on the sub was bad. So i would try taking a multimeter to the voice coils and see what it reads Quote Link to comment Share on other sites More sharing options...
adam6604 Posted July 6, 2011 Author Report Share Posted July 6, 2011 yeah when i first got them i multi metered the voice coils and they were all reading the same, but ill check again Quote Driving my 2008 Dodge Ram 2500 MEGA cab with the 5.7 hemi.

Socky Posted July 6, 2011 Report Share Posted July 6, 2011 Since the one near the port is moving more, means its most likely is unloading(basically free air). You might need to redesign your box.
