Measure the complete cable path between the audio components, including bends, rack depth, and any routing around equipment, then select a length that provides modest working slack without leaving excessive cable to manage. Audio cables are available in multiple lengths, so match the option to the installation path and account for the space needed to connect low-profile plugs.

These audio cables use RCA connectors on both ends, making them compatible with sources and receivers or amplifiers that have matching RCA analog audio ports. Check that the source output and receiver or amplifier input use the same left-and-right RCA connections before selecting a cable length.

Shielding helps audio cables reduce the effect of electromagnetic and radio frequency interference that can introduce unwanted noise into an analog audio signal. Cables with layered or spiral shielding can support cleaner signal transmission, particularly when routed near power wiring, networking equipment, or other potential sources of interference.

Flexible jackets make audio cables easier to route and organize during installation. Low-profile connector bodies can help cables fit into tight spaces behind equipment and in other crowded areas.
