etaks_crew Posted November 3, 2009 Report Share Posted November 3, 2009 where did the noise come from off the sub? Quote Link to comment Share on other sites More sharing options...
drumminian Posted November 3, 2009 Author Report Share Posted November 3, 2009 it sounds like theres something hitting the cone...i thought it was the leads at first but it seems like its coming from below the voice coil....I wish I had a better video camera then my iPhone or I would take a video....I don't believe the sub is blown how ever I tested it with a DMM and it was fine and nothing was rubbing when I manually depressed the cone to test for a blown coil....any ideas?

bigredishott Posted November 3, 2009 Report Share Posted November 3, 2009 If you are testing free air prob bottoming out. But in the box very well its coming apart. My type rs tore apart a prefab from best buy. I would try them in a diff box see if you have the same probs. Anyways Good luck! PS envious wish my 1st set up was as nice as yours. I had 2 pyle driver subs and I wanna say a profile amp that I had gotten at the wiz. lol Quote Alpine CDA-9847 HU F Highs 2x Infinity Kappa 60.9CS Powered by Eclipse EA4200 Glass door panels R Highs Infinity Ref. 9622i powered by HU 3x RF Punch HX2 RFD2210 Powered by MTX Thunder 81000D Box Vol. 3.259 before displacement, Tuned 36.6, Port area 54" Link to comment Share on other sites More sharing options...

etaks_crew Posted November 3, 2009 Report Share Posted November 3, 2009 (edited) I would put to much power on them while free airing them but the noise you heard while you were free airing them was it the same noise you had before? You box might be just leaking air and not coming apart and perhaps your bottoming them out in the box as well. Do any of you friends have a box you could try out? I'd feel around the box while the subs are kind of bumping a little bit but before that noise starts. try and see if you can feel air leaking out.

drumminian Posted November 3, 2009 Author Report Share Posted November 3, 2009 no one I know has 15s lol when I was free airing it was kinda similar to it in the box except it was not as loud and you could bearly hear it...the subs get pretty loud before the noise started to occur but some notes do it at lower volumes than others shits so confusing Quote Alpine CDA-9887 15" FI BL JBL BP1200.1 Rockford Fosgate p142 4" front Rockford Fosgate p1S652 6.5" rear Optima D35 yellow top under hood Big 3 all in a 1997 Toyota Tercel Link to comment Share on other sites More sharing options...
drumminian Posted November 4, 2009 Author Report Share Posted November 4, 2009 could it be a bent voice coil in both of them? i found a video on youtube that had a sound similar to what I am experiencing and someone commented saying it could be a bent coil Quote Alpine CDA-9887 15" FI BL JBL BP1200.1 Rockford Fosgate p142 4" front Rockford Fosgate p1S652 6.5" rear Optima D35 yellow top under hood Big 3 all in a 1997 Toyota Tercel Link to comment Share on other sites More sharing options...

hotshot27 Posted November 4, 2009 Report Share Posted November 4, 2009 (edited) I had some rattling issues, i ended up sealing the inside of the box with silicone and double baffled the front. i then used some 3M putty sealant between the subs and the box. i gained 2.4-2.6 decibels from that alone. but if yours is doing the same noise outside of the box, then it sounds like damage to the sub or bottoming out.
