## 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.
