## Questions & Answers

**Q: Is this price for a pair ?**
A: yes i did get a pair, that was the way that they were packaged

**Q: What size/type  connectors would be best for this?**
A: Regular spade connectors....I used the original ones when I replaced them

**Q: Does this come with speaker wire ?**
A: No, mine did not. I bought it later from a store in town.

**Q: Can they be mounted on a 7 1/2" cut out?**
A: don't think so,...........unless...........you make a reducer plate that attaches to your mounting area with the proper sized hole in it to mount the speaker. You could make it out of a piece of opaque plastic, such as modified acrylic or expanded styrene or some other suitable material.  If you have craftmaking skills it doesn't present much of a challenge, imho.
