Going to choose:
https://www.amazon.co.uk/dp/B09VKZPST7?smid=AISREEIOH9TSP&ref_=chk_typ_imgToDp&th=1 (because it has aux port)
https://www.amazon.co.uk/soundcore-Subwoofer-Waterproof-Floatable-Bluetooth-dp-B0CQ55VQH8/dp/B0CQ53RVTW/ref=dp_ob_title_ce?th=1 (wanted it because of the lights, will think of something for that – sounds like a raspberry pi project – https://www.raspberrypi.com/news/graphic-equaliser/)
will consider a smaller unit with more base power if the one selected is too big
