Phoenix Gold XS6600 Amp Help

I bought this older Phoenix Gold XS 6600 amplifier. Reading the manual for it, i am a little confused on the total RMS and what I could realistically do with the amp (page 2 of the PDF).

I want component speakers in the front, coaxial in the rear, and one modest subwoofer. Is the 14.4 vdc gonna be a problem with the headunit for the subwoofer?

Would I be able to find a set up speakers that would be possible with this amp?

Any help is appreciated

 

Basically 50W @ 4 Ohms measured at 14.4VDC, so it will probably run a little less than that since our trucks sit at 13.something VDC when turned on. I don't see an issue unless you are wanting to squeeze out max power.

 

Hey thanks for looking helping with this. Nah not looking to squeeze out max power, I just don't want to have speakers that would be blown or underpowered with the amp.
