DESCRIPTION FOR BOSS 4-INCH DUAL CONE REPLACEMENT SPEAKERR - BRS40 Product Overview 4-Inch Dual Cone Replacement Speaker, Individually Packaged In Clamshell 50 Watts Peak Power Handling; 25 Watts RMS Power Impedance 4 ohms Frequency Response - 100Hz-18kHz Polypropylene Cone Material Mounting Depth - 1.7-Inch

Review: 車に備え付けのダッシュボードスピーカーの音ががっかりだったので 同サイズのこのスピーカーが意外に格安だったので購入 低音は満足のいく音でした。高音もう少し出てくれると更に良かったのですが 良く見なかった自分が悪かったのですがペア（２個）価格かと思って購入したら １個でした。（慌てて追加購入しました(^_^;)）
Review: Bought this because I could not get the identical mounting sized 4ohm 40Watt speaker from the vehicle manufacturer: works as a perfect replacement and had the identical mounting screw distance too! NOTE: this speaker has solder connections for best sound.

## 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.
