A:AnswerI don’t personally have any 4ohm speakers hooked up to mine but when going through the first time set up it does ask what ohm speakers you have hooked up and it does give 2 ohms, 4 ohms and 6 ohms to pick from during the set up.
A:AnswerYes. In fact, I have all premier Klipsch reference speakers hooked up to it and it sounds amazing. Along with the Atmos setup too. The specs on those speakers are 8ohms.
A:AnswerI'm assuming you have Bluetooth, Optical digital audio, Coax Digital audio and Analog stereo inputs. This receiver has all those connections available.
A:AnswerThe manual and spec sheet list no additional details for the ARC feature of the PIONEER ELITE AV UNIT_VSX-LX303.

A:AnswerTechnically no, If your system came with a wiring harness then you would wonder past the beginner stage and venture into some rewiring then yes. You will need to splice the harness and connect the correct speaker wire to the receiver corresponding output. Hopefully helpful
A:AnswerYes. 8 ohm impedance is ideal. However, you may want to play it conservative when it comes to volume since the speakers are older and are rated for 40/50 watts. That is
about half off the wattage that the vsx lx303 can put out. If you are looking for easy upgrade for other speakers in the future, this could be a good fit. If not, you might want to get something with less power and fewer channels.
