## Questions & Answers

**Q: Is the light and the time suppose to stay on constantly?**
A: Hello Cade,
There are 2 links below which should help to answer your question.
The 1st will guide you to a user manual.
The 2nd is a link to Boss Support

**Q: Do I just need a couple of speakers and some speaker wire to install?**
A: Yes you need speakers and wire

**Q: Can i just hook it up to my amp, instead of using the head unit outputs?**
A: Hello Tanner,
 Yes, you can use the pre-amp outputs to connect to your amplifier.

Please see the link below for more information.

**Q: Besides the volume knob, what’s the difference between this and the boss 350b? There are no reviews anywhere**
A: Hi Dedmon9

The 350b has an RDS Tuner, where the 300b doesn't.

("RDS" stands for "Radio Data System" and it allows FM broadcasters to send far more than just an analog audio signal out over the air waves. Using a 57 kHz "subcarrier," stations can transmit digital RDS data for reception by RDS-equipped FM tuners).

## Customer Reviews

### ⭐⭐⭐⭐⭐ Bluetooth only receiver
*by J***E on July 16, 2025*

This head unit and speaker set is great, easy install good performance for the price!

### ⭐⭐⭐⭐⭐ Great product
*by D***A on March 30, 2025*

Great product have it hooked up to 4 Rockford Fosgates sounds great , a lot of outputs got alot of different things, love how it’s dial volume not push button , I purchased a backup camera separately works great , Highly recommend

### ⭐⭐⭐⭐⭐ Excellent upgrade
*by J***N on July 15, 2024*

got this for my pontoon where the original quit working. someone at the shop says the screen goes out on a lot of units, so I picked this one as there is not screen to get water into. also, saw no use for the radio feature of the original unit, so like that this is primarily a Bluetooth system. I don't know the technical reasons, but this unit plays louder and sounds better through the same speakers and stays connected to my phone when I switch the engine off moving the key into accessory power mode when we park and play.
