Will be using a splitter but as far as the settings I am a little confused
Yamaha’s are weird when it comes to bass.. also yes you can just use a splitter.
Here’s a few tips to help you increase your bass regarding YPAO.
options -> Tone control -> Bass -> +6
Options -> Subwoofer/Bass -> Subwoofer trim +6
Options -> Subwoofer/Bass -> Extra Bass - Off
Under on screen -> setup -> manual -> levels -> Subwoofer trim -> (keep this is the negatives) [anywhere from -9 to -2]
& increase the gain on the back of the sub rather than using the trim under levels.
Reading this short thread will give you a nice example of what these settings done to a SVS PB2K w/ a Yamaha 2070.
Also here’s examples & graphs detailing what these settings achieve.

Don’t be afraid to turn **** up. Until you get a calibrated mic — https://www.minidsp.com/products/aco...urement/umik-1
Download an SPL meter on your phone were You can get a rough estimate of your volume relative to every other channel.
At 0 MV all channels should be calibrated for 75dB when using the test tones
It’s okay to run your sub hot. I have mine 5dB hot.
Here’s my settings although different subs
Sub gain - 3 o’clock
AVR trim - -5dB
Sub trim (under options) - +6
Tone control (bass) [under option] - +6
It’s best to have a high gain with a low trim setting.
Also to answer your question above, the sub gain is controlling how much voltage is being sent from the plate amp to the driver. The AVR trim is how much voltage is being sent through from the AVR to the sub via your inputs. The sub trim (under options) is just additional headroom added to the AVR trim; so assume your AVR trim is -10 - +10 there’s 20dB of choice, once you increase your sub trim you now have 26dB of choice. Tone control is controlling all channels, fronts, sub, etc. Hope this helps some.
May be helpful to read the subwoofer calibration thread below

The Sub Trim control has been tweaked in recent years since the inclusion of the "Extra Bass" feature.

In the attached graph you can see what the Sub Trim is doing with a crossover setting of 80Hz
was the OP of the thread above. He had significant improvements once initiated these settings. He or I or others here will answer any questions you have. Don’t be afraid to ask.
Edit: after you run YPAO & it asks if you want “YPAO volume” on or off click off..or you can go to options -> YPAO volume-> YPAO Volume -> off. This is a dynamic setting for nighttime listening. It will kill your bass unlike Dynamic EQ or whatever it’s called on Denon.
