Is the light and the time suppose to stay on constantly?

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 https://bossaudio.com/product/mgr300b/ https://support.bossaudio.com/hc/en-us

Can i just hook it up to my amp, instead of using the head unit outputs?

Hello Tanner, Yes, you can use the pre-amp outputs to connect to your amplifier. Please see the link below for more information. https://bossaudio.com/product/mgr300b/

Besides the volume knob, what’s the difference between this and the boss 350b? There are no reviews anywhere

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).
