Rockford FosgatePMX-0 Punch Marine Ultra Compact Digital Media Receiver

I’m looking at putting this in my jeep. what would i need to make the dash/sound bar work with it? i see it has input for amp and subs

Will this run towers speakers and sub with a 5 channel amp?

? bought one and i love it but one thing i dont like is if i turn the volume to high it shuts off does anyone knows why it does that and what can

Will this fit in the factory hole in a polaris ranger?
