I was just writing about this in another thread
Did you break them in or just run full power into them right away?

Heading to CARTOYS they still under warranty. I still have my old home made bass tube with cerca 1985 8" subs that thump real hard.

turn the volume down next time, you are more than likely expecting too much from dual 8"s and compensated by turning volume up louder until distortion or you cranked bass boost up.....i have never "accidentally" blown a sub in my life (be doin this 15+ years)

Well that blows my theory out the water

Agreed. Those specific JLs he has likes 150-200 watt range each and that amp can put out near 600 watts with good electrical. Too much power for too long or artifical bass boost (via the amp or headunit) can easily shred those subs

I'm thinking a 1985 driver is likely 8 ohms.

You're probably right. In 1989, my Rockford Fosgate pro series 12's were dual 8 ohm wired to 2 ohm on a Nakamichi PA400M. 220 watts x 2 @ 2 ohms. It hit hard to. The car was a Ford Probe.

Seems like JL, Rockford and others aren't redesigning stuff every few years like they used to. I do miss the look of the older JL's with the dome dust cap the current ones look boring.
