I have a 15" L7 Kicker and and 1000RMS PDX Alpine amplifier... i had it all hooked up and it sounded fine..it was only running for about two hours and it just stopped working. I noticed my amp was off and and all 4 fuses were blown. I replaced the fuses and the sub barely playedand souded almost blown but i dont know how thiscould be seeing as in a barely played it and i didnt turn it up loud at all and now it wont make a sound at al.. I checked to see if power was goig through and power reaches all the way to the sub. When i touch the power indicator to anywhere on the sub it makes a weird sound but this is the only time it will make any sort of sound at all..

Check your RCA cables to make sure you are getting signal. The amp isn't in protection is it? Also, if you have a multimeter, you can check to see if you are getting any power out to the speakers. Also, check to make sure your subs aren't blown. Keep me posted.
check to make sure your box is securely sealed and that the box itself is not rattling. if not, most subs require a break in period where they can not be played full gain/full volume for the first 48 or so hours... did you break in your subs by paying it softly the first day and slowly turning your amps gain and receivers volume up the next couple of days. if not, it is likely blown
The Kickers are the way to go here- they move more air because naturally a 15 inch square has more area than a 15 inch circle- thus more air moved =greater spl =LOUDER. The only thing that might get some equality between the two is if the db drive round sub has a far greater xmax that is the linear movement of the cone from start to full excursion-IF the db drive has drastically larger xmax than it could possibly outperform the L7 because of greater cone excursion which also =more air moved=louder---- haha thats a tricky one but ya got me wondering too so let me know what you find out please-Ive always been a kicker fanatic so im probably biased towards their products-never heard nothing bad about db drive though either im in salt lake city i dont know of anywhere out here that even carries their products so i have nothing to reference by except kicker L7's kick asssssssssss
ok im going to try to explain this you have 2 voice coils , i will refer to as vc1 and vc2, you take vc1 positive and connect to vc2 neg then use vc1 neg and vc2 pos to the amp according to pos and neg signs.
Im guessing that it is possibly blown... either you ran too much power to it, or it was hooked up wrong... you should unscrew the sub from the box and look inside to make sure that it is connected correctly.... positive to positive, negative to negative,,, if they so much as touched then the L7 could very well be blown.... smell the magnet and if you smell a burnt smell... it is blown... maybe turn your amp down a little... its possible that it is also in protect mode because you are running too many watts to the amp. Feel free to ask if you have any other questions.... Please rate! :D And good luck... i really hope its not burnt out. that stuff is not cheap.
