Thinner alternatives to using RCA shielded wire?

[Air Conditioner]

Closing up the DolphinBoy again and the shielded RCA cables that I've cut are making the closing doable, but tighter than I'd like. Anyone have some thinner alternatives for lines needing shielding like video and audio? Thanks!

Use the WiFi antennas wires. They are shielded and work perfectly
