## Questions & Answers

**Q: Will this speaker fit a Bose 51 outdoor speaker?**
A: It will fit physically, but the Bose original was a 4-ohm, instead of 1-ohm. If you have a pair, check the impedance of the other speaker. Both should be the same. I had to go to eBay to find a 4-ohm.

**Q: This is for the whole speaker 9pc?**
A: No. This is one of nine.

**Q: Is this the replacement speaker that will fit a 2002 cadillace escalade driver side door ?????**
A: I'm not sure, I used it for my Bose 901 speakers..... Sorry

**Q: is the foam surround on these the new style that lasts longer and if so how many years is it good for?**
A: The speaker works great, sounds as good as new to me.  I expect the foam and the rest to last longer by keeping them dry and out of the winter weather.  The environment makes the difference.

Works almost as good as new. It fits the older Bose 901 outdoor speaker enclosure. This speaker is not rated for outdoor use but otherwise it works great.
