09 Herman Karman

So i got and SE Legacy and the 9in sub has some problems. the car now is at 52,000 miles so its no longer under warranty but when it was the same thing happened. the sub would disconnect like it would stop working all together. I brought it in and i got the sub replaced for no charge. the dealer said that they never heard of this before in their 09 outbacks or 09 legacys. did anyone else have this happen to them???

That's a new one.

It's Harman Kardon, btw.
