## Questions & Answers

**Q: What is the ohm rating on these speakers?**
A: 4 ohm's

**Q: Does this fit 2011 Ram 1500 dash speaker?**
A: The only sure way to tell is to take out the old speaker and measure it. If yours is not the size of the BRS35, there are other sizes available.

**Q: is it important to use the plastic mounting ring?**
A: Not if the speaker fits without them.  I installed them in the front doors in my old Escort without them and they work fine.

**Q: Is it a pair of speakers or just one speaker?**
A: Just one at a time. So you really have to order 2 of them if you need a pair.
