I agree with the others. Never ever sing out of home audio speakers just not capable of handling human voice for singing. Mackie thump is solid for speaker. Get a cheap laptop and use something like Karafun or even just youtube for your songs. You can hdmi out to your tv or even use the laptop itself for your screen. I weld also get rid of your mics/mixer those are not for karaoke.

If you dont have alot of money you can use these mics https://www.amazon.com/Fifine-UHF-Dual-Channel-Wireless-Handheld-Microphone-Karaoke-Wireless-Microphone-System-K036/dp/B01N6448Q4/ref=sr_1_18?crid=JS1QWBVJVT7Y&keywords=fifine+mic&qid=1647613214&sprefix=fifine+mic%2Caps%2C236&sr=8-18 They are not perfect but work well enough and have built in reverb which is nice. I have used them many times and fine for home use.

A little mixer would be nice as well. My choice is this Mackie https://www.amazon.com/gp/product/B0849LT2HD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 tons of features and tons of vocal presets for you.

Good luck with whatever you choose!
