I’ve recently bought a REL storm and want to connect to the 2nd line level sub output, the REL has 3 inputs, high level, low level and balanced, and uses 3 pin XLR plugs to connect to the mono built in amp, I know I need to connect to the low level input but as the cable is connected with 2 positive and 1 negative do I need to connect the 2 positive wires to the positive on the RCA plug which goes into the A/V amp or do I just need connect 1positive?
It sounds like you've got the high level cable which terminates in a Speakon plug rather than balanced. The low level should just be RCA I think?

Could you post a photo of the cable and the back of the Rel?
