hi, i want to make wireless connections between 5.1 channel sub woofers and all its other small 5 speakers

Solution
Depends on how those speakers connect to the sub and/or receiver. There are plenty of wireless speaker kits available but I doubt you will find the cost and the number of things you need to connect worth it. Something like this product https://www.amazon.com/Multichannel-Wireless-Transmitter-Surround-Speakers/dp/B01M1BK1U3/ref=pd_day0_23_3?_encoding=UTF8&psc=1&refRID=VC39HCSB1E3N90X00F5Y and you need one of these for each speaker https://www.amazon.com/Multichannel-Wireless-Receiver-Amplifier-Speakers/dp/B01LX35T6D/ref=pd_sim_23_1?_encoding=UTF8&psc=1&refRID=9Q2T9T5GF0PX4HQFF493

Better off just buying a wireless audio system to begin with.
