I hope that sub was used.

That kind of failure looks like age/fatigue. Your little base session probably just exposed/exacerbated an existing issue.

My JL 10w 0 had the same foam-failure on the way back from ZdayZ this year, but it's about 4 years old so I think it did ok for JL's entry-level (at the time) sub.

If you want to be "safe" just get a single voice coil, 4 ohm sub. But the manual for your sub says it can handle 2 ohms bridged.

I would do a little research on the amp. Some amps are able to "handle" difficult loads because they have overly-intrusive protection circuitry. (that just shuts down the amp after a few minutes of high power output.)

If that's the case with your amp, it's probably not worth it to go 2 ohms bridged again.

But if you find that your amp is just "overbuilt" and can play into 2ohms bridged without having to take a "time-out" every other song, go with a dual 4 ohm (that can be bridged and present a 2 ohm load to the amp) or just get another 2 ohm single voice coil.

 

Thanks Z1, I sort of had that feeling... I got this as part of a trade and I think it may've been somewhat fatigued... Oh well, can't go back to the guy now since it's been a few months.

I think I'll go with a RF P3 4ohm DVC or something similar that will sound half-decent in the box I have.

Thanks for all the input!
