Can a Rockford Power 300 Mosfet run a single 15?

I'm curious if an old school Rockford power 300 mosfet can run a single 15? The amp is four channel and the sub is dual 2 ohm. The sub is rated at 1,500 rms. Any thoughts on if the sub would be underpowered, or, not? I was thinking of just using old school amps. A power 150 would run the mids and highs.

A lot of things CAN be done that probably shouldn't.

A 4 channel and D2 probably makes about the worst match up possible.
You could do something ridiculous like bridge both pairs to 2 ohms which would give you 300w on paper -- maybe more given RF's history of under-rating amps (although - it could also be less since the amp's not technically 2 ohms stable bridged -- some amps struggle when they're stressed). And it would **** up a huge amt of current for that relatively low amt of power.

Not worth the effort IMO.

Great amp and very underrated (800 watts), like all old school RF amps. Use it as intended and get a mono amp for your sub.
