General discussion

difference between aux input and rca intput?

Aug 23, 2008 3:46AM PDT

I just have a quick question. In my car I have a deck that has both an aux input in the front and rca connectors in the back. And I was just wondering if there is any audible difference between the two.

Thanks,

aux/rca

there is really not a big difference between the two hook ups. the aux input in the front is an easy plug and play feature where the rca is more of a permanent option. either way you go the sound should be the same.

Difference between aux input and RCA input?

Hi,

The front is a convenient aux input as stated.

Normally however, rear RCA connectors are outputs.

If you are sure that these are inputs then they are for
connection to more permanently mounted alternate
and/or additional audio items.

Need make/model to know for sure.

Without knowing what make/model vehicle you have and what audio options are installed, it's difficult to tell.

From a sound quality perspective, there isn't much of an audible difference at all. Depending on your vehicle, however, there may be a bigger difference in the inputs' functionality.

For example, if your vehicle has a rear seat entertainment option, the RCA may include a video input for attaching an A/V source such as a portable DVD player or video game system. (Your standard 1/8" aux-in doesn't support video.) The rear inputs may only play sound out of the rear set of speakers if your audio system includes a dual zone option.

The RCAs are most likely not outputs, especially if your stereo is an OEM unit.
