No, front speakers were blowing straight off the HU, no external amp installed. Plus it wasn't the tweeters, it was the low end that would go out. Called Crutchfield after the second set blew asking for help. They said it was a head unit issue, if I wanted to do a warranty return I would have to call pioneer. Supposedly they had quite a few complaints about the pioneer HU's and how they distribute power.
I opted to try the polks, been good for over a year now.
