Setting up 2 power amplifiers to setup at once help?

Hey guys I’m using a pair of Polk rti a7s with a Denon Poa 2800 amplifier and Denon receiver 2801. I just bought another power yamha PC2002M power amplifier which has a little more kick then the denon 2800. But I will be giving the denon 2800 to my dad when he gets back from his trip. I just want to know is it possible to hook up the 2 power amps to my setup at once ? And is it worth will I see a big difference in sound quality and performance ? I’m just curious and want to do a bit of experimenting only if it’s possible? Don’t want to risk blowing anything up. Thanks guys

You understand what you are doing? Whether it sounds good or not, I am all for experimenting and learning. Sure, try it and see. You won't break anything unless you short out connections etc. That is your risk. Take care not to set the volume to max.

Yes, the top diagram is correct! Just get two jumpers (a few inches of wire will do) for each speaker. Forget about bi-wiring (the correct term). Use only one amp at a time with your two speakers - after you install the jumpers!

@noromance The OP is a novice! My advice is correct! The two amps must be identical for bi-wiring to work properly! Let him install two jumpers per speaker and use just one amp at a time!

@roberjerman I think we've covered that. He could sell both amps and get a better single one that would be the best solution. But then again, you don't think amps sound different.
The guy wants to try it out, play, and learn and wants to check in if it's okay. It's low-end kit. Let the fun and learning begin!

@noromance With two amps of different gains the bass and mid/high sound levels won't match! That would hardly make for good listening! The OP wants to give his father the Denon and keep the Yamaha for the Polk's. I personally would do the opposite! I think the Denon will sound a bit better than the Yamaha! You are right though - the OP should sell either amp and get something like a Levinson ML3. Then he'd need a real preamp to match - like an ML1. Next, better speakers and onward down the rabbit hole!
