Rockford Fosgate Amp / Rokker XT Series Speakers

[IRONMAN]

Hey gang. For one of my winter projects I am adding an amp to the bike.
I put J&M Rokker XT Series speakers in the fairing a few years ago (part number 40-453). I just purchased the ROCKFORD FOSGATE PBR300X4 4-CHANNEL AMPLIFIER 300W RMS and the install kit. I noticed in another forum today that this amp is spec'd for 4 ohm set up and the Rokkers are 2 Ohm. Am I screwed? Is there a way to use these together?

I also have two Boom speakers on my quick release tour pak with quick connect. If I can use the amp with the Rokkers should I set up the amp for 4 speakers or just use it as 2 channel on the fairing speakers?

Thanks in advance for your help.
