javy101 Posted August 6, 2008 Report Share Posted August 6, 2008 this is a sad day for me i just found out that i have a blown fi btl 18" 2008 model fully loaded. yesterday i was taking a cruise round town and put some white girls on (song) the song was clean and undistorted until i all of a sudden a loud horrible sound came from it it sounded like it blew. i just got done opening up the box to see the damage and i found (i think it was the spiders) that the speaker had ripped right inbetween were the cone and the spiders meet everything almost all the way around it was ripped. R.I.P. and i only had it playing for a week now i need to figure out wat went wrong. i am powering it with a sundown 3000d at one ohm so i dont think it was to much power. besides if it was to much power it would have melted this just ripped not one smell of burnt or one smoke puff came out. plz guys i need to figure this one out plz help me find wat went wrong i will have pics up later on this night Quote Link to comment Share on other sites More sharing options...
Derrick824 Posted August 6, 2008 Report Share Posted August 6, 2008 What are your box specs? Volume, port area, tuning? Quote Link to comment Share on other sites More sharing options...

wL<3bass Posted August 6, 2008 Report Share Posted August 6, 2008 Even though you dont hear distortion you may be clipping the amp did you set it with a dmm and use an oscilloscope to check for clipping?

Decaf Posted August 6, 2008 Report Share Posted August 6, 2008 (edited) hmm ~3000w on ~2000w sub + possibly incorrectly set gains + bigish enclosure for power + playing song at box tune freq = _________________________ blown btl well since you ripped your suspension apart its likely ur box is tuned higher than u think plus a little too large a box for more power, and u were playing well below tune freq likely Edited August 6, 2008 by decafcappucino Quote Link to comment Share on other sites More sharing options...
David Posted August 6, 2008 Report Share Posted August 6, 2008 box is way to big for that power, scrap the box and start over, seeing how your gonna have to send the sub in to have it reconed. Quote Link to comment Share on other sites More sharing options...
Boon Posted August 6, 2008 Report Share Posted August 6, 2008 box is way to big for that power, scrap the box and start over, seeing how your gonna have to send the sub in to have it reconed. Totally agree - Did you ever watch the sub when it had a bunch of power flowing to it? The excursion would have been horrendous. You may be able to get away with just modifying your current box... put some BIG 45's in the corners, maybe double layer the panels inside the box, do what you have to to get the volume down.
