Hi @Gaucho 

Thanks for your post!

Those speakers (rocks!) are rated at 8 Ohms each, so there should be no issue doing exactly as you describe. Please ensure to wire the speakers in parallel.

The subwoofer, however, is another matter. It is not powered, so you cannot connect it to the RCA subwoofer connection on the Amp, and with 4 other speakers connected, you cannot wire it as a speaker either. I’d recommend purchasing a third-party, single-channel subwoofer amplifier to fit between the subwoofer and the Amp. I cannot recommend a specific one, however.

I hope this helps.

Thank you
