thehoe92 Posted April 21, 2009 Report Share Posted April 21, 2009 something in my car makes a rattle noise. now wait I can see the replies now. its a new sound and it sounds like it comes from inside the sub. high volumes does it for me. how do I use a DMM to check if its blown? or what are the symptoms of a sub on its way out.

dwz Posted April 22, 2009 Report Share Posted April 22, 2009 I would also like to know this. I blew a sub like that and it rattled inside. I think the voice coil was fried or something. Any answers? Quote Link to comment Share on other sites More sharing options...
lanman31337 Posted April 22, 2009 Report Share Posted April 22, 2009 Use your DMM with OHMS settings on the coil. If it doesn't read what the coil should read, then it's cooked.

dwz Posted April 22, 2009 Report Share Posted April 22, 2009 I just learned that this morning. Yep, your Digital Multimeter will work Quote Link to comment Share on other sites More sharing options...
raytard Posted April 22, 2009 Report Share Posted April 22, 2009 it smells like burnt electronics, its probably blown (especially if it smells like that AFTER its been off for a while, like you get in the next morning and move it and smell that) if the reading on the DMM set to OHMS isnt approxomately what it should be (say a 4ohm coil can be between like 3.5 and 4.5....and yours reads 1ohm, or even nothing, its blown) if it sounds like a slinky is in there when you move it by hand, its blown if it sticks in, out, or anywhere inbetween, its blown if you hook a battery (like a 9v) to the wires it should pop in or out, if it doesnt, its blown now that you know all about the coil, tinsels can break (they go from the terminal, over or through the spider(s) to the coil at the center, sometimes they will snap or burn through, usually obvious (can also turn black from getting too hot) cones is obvious, they have holes or cracks same for surrounds, it should be constant baskets shouldnt have cracks terminals should uh....terminate properly spiders should be glueed to the basket and the voicecoil former, press around the seams to make sure Quote Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...
