hawkins6423 Posted March 23, 2009 Report Share Posted March 23, 2009 So A few weeks ago, I am driving down the road and banging a loud 30hz tone on my 12" BTL. The tone gets weaker and weaker over a 10 second run and I smell it.... the burning smell.. the blown speaker smell. IT completely stopped working. So I took it out and examined it. It looks 100% fine, tinsel leads still good. clean motor etc I hooked a 6x9 up to my amp to test for possible DC voltage coming out of the speaker terminals, and the 6x9 played correctly. Any ideas?

It is an AC voltage out of your amp. Get a multi Meter and check your ohm load if nothing then check connections if thats still good then you got a nice new paper wait. Time to get a recone.

hawkins6423 Posted March 23, 2009 Author Report Share Posted March 23, 2009 What would a burnt coil be caused by? No I know AC voltage is what comes out, but ive also heard of things shorting in amps and DC voltage coming out and ruining the speaker. It is a single BTL so I know all the connections were good... Do you possibly know if its coverd by warrenty, I bought it from Fi in November of 2008. (5 mos ago i think) Quote Link to comment Share on other sites More sharing options...
AI James Posted March 23, 2009 Report Share Posted March 23, 2009 theres no warranty on BTL's Quote Link to comment Share on other sites More sharing options...
jvillefinest Posted March 23, 2009 Report Share Posted March 23, 2009 burnt coils are caused by either excess power causing heat, or a clipped/distored signal causing excess heat. In the end excess heat kills a subwoofer. Fi probably will not cover this, because it is due to mis-use of the speaker. Time for recone kit.

Clif Posted March 23, 2009 Report Share Posted March 23, 2009 could be cause by a lot of things, To much power. Clipped or distorted signal. In wrong box...

hawkins6423 Posted March 23, 2009 Author Report Share Posted March 23, 2009 Damn lol... I bet it was that shitty soundstream line driver pushing a distorted signal into my sundown..... because I doubt 1500 watts would kill it.. i think.

hawkins6423 Posted March 23, 2009 Author Report Share Posted March 23, 2009 Could someone point me in a good direction for instructions on a re-cone? Quote Link to comment Share on other sites More sharing options...
hawkins6423 Posted March 23, 2009 Author Report Share Posted March 23, 2009 Oh I did have it in a 4 cu ft box, tuned to 30hz... That might be why too. IT just sounded A LOT better than the 2.25/2.5 reccommended in my quad cab truck.. Quote Link to comment Share on other sites More sharing options...
