Advice on LED strips

[Tran]

Does anyone know what I can do with my led strips? 
What I’m trying to do is join two led strips together but I’m unsure what I have to do. (soldering, is there something I can buy to join them together, tape?)

You can solder or use this: https://www.amazon.com/dp/B07YFR63JP/ref=sspa_dk_detail_6?psc=1&pd_rd_i=B07YFR63JP&pd_rd_w=os8Ap&pf_rd_p=48d372c1-f7e1-4b8b-9d02-4bd86f5158c5&pd_rd_wg=8Jwg9&pf_rd_r=MWQZZ2WA6ANT7B158HV7&pd_rd_r=2adeceb4-bf16-4c48-9219-48b9de7d2c36&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExS0xKQTVQRDhBT1hEJmVuY3J5cHRlZElkPUEwMTEyNTQ3MldSV0JFRE8xUkM2TSZlbmNyeXB0ZWRBZElkPUEwNzM0Nzc0SEI3MjZWRVkzMzRQJndpZGdldE5hbWU9c3BfZGV0YWlsJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

 

Just don't join two large 16.4ft spools together . You can only put so much current through them.
