Question about Jl Audio 12W7 Car Subwoofer
OMMITING AN UNPLEASANT SOUND, SOMETHING LIKE VIBRATION OF SORTS FROM WITHIN THE ENCLOSURE, ALONG WITH AN ODOR OF WELL NOTHING GOOD IM SURE, I BELIEVE THE VOICE COIL HAS COME LOOSE FROM ITS INTERIOR PARTS ORSOMETHING AND ITS VIBRATION IS WHAT IM HEARING. ANY THOUGHTS IS JL THE ONLY PEOPLE WHO CAN FIX THIS, ITS NOT UNDER ANY WARRANTY BUT IT WAY WORTH FIXING. BADDEST SUB I HAVE EVER HEARD
The smell and sound are the voice-coil having become delaminated and unravelled - usually due to a clipped signal.
The 'watt' is a thermal measurement.
To prevent this failure in the future, I'd suggest viewing a tutorial on setting your amplifier's gains properly.
In fact, JL Audio has a nice, flash-based tutorial on it.

For the record, I've never seen an Olympus /anything/ at World Finals. Be wary of any product that claims 'competition,' especially if it looks fancy.
Loud is often ugly. Like fast.
If you're going to buy new equipment (or used, for that matter) look into the more popular internet direct brands;
Plenty of people on the forums will be happy to contribute to your success in mobile audio - if for competition or just for personal use.

The rottem electronic smell is the voice coil burned up as well as the bad sound, isn't the 1st time i have seen a JL sub blown. not worth fixing buy a new one the cost is not that much more repair on them is 250 - 450 depending on how bad it is and only JL can do the repairs as they dont authorize repair shops access to their voice coils. however i can sell you a new sub with full JL factory warranty drop shipped to your door for about 475$ or I could do you a way better sub ( the baddest competion sub made in the last 5 years) an olympus 2412 dual 2 ohm 5000 watt monster that has user replaceable voice coil options and is killing the competition circuit right now for about $275.00 shipped. it will stomp 2 13 w7's into the ground all day long. 2 subs vs just 1
