## Questions & Answers

**Q: What is the RMS rating per channel?**
A: Hello,
The MGR350B outputs a total of 30 Watts RMS per channel.
Thank you,
Boss Audio Support Team

**Q: I see it's a 3 year warranty on the stereo?? I got one almost a year ago and the screen blacked out after 6 mounts what and who do I get a hold of to**
A: You should check your order and either the seller or BOSS would be my guess.

**Q: How long are the USB and aux input cords?**
A: 12 inches

**Q: Why is the one without speakers more expensive? We have speakers.**
A: No idea.  I ordered the one with speakers (only a few dollars difference), but only used the head unit.  Saving the speakers in case things change later and I want to install them.
