Frequently Asked Questions

What is this adaptor used for?

The SGI21 is used to join two female-ended RCA sockets or cables together — resolving situations where both connection points terminate in female sockets. It is the male-to-male counterpart to the SGI20 (female-to-female) and covers the opposite wiring scenario.

What is the difference between the SGI21 and the SGI20?

The SGI21 has male RCA plugs on both ends and is used to connect two female RCA sockets or extend a dual female-ended RCA cable. The SGI20 has female RCA sockets on both ends and is used to join two male-ended RCA cables. Keep both in your install kit to cover either scenario.

Does this adaptor degrade signal quality?

The gold splice connection helps maintain signal integrity. Any additional connection introduces a very minor resistance, but in practice the SGI21 is transparent for audio signals at typical car audio cable lengths.

Is a pair one adaptor or two?

One pair equals two adaptors — one red and one black — suitable for one stereo (left/right) channel pair.

Is this compatible with all RCA cables?

Yes. The SGI21 accepts any standard female RCA socket on both ends and is not brand or gauge specific.
