Is there a cable to turn aux jack into rca jack?

Yes, you can easily convert an aux jack (typically a 3.5mm stereo jack) to RCA jacks using a 3.5mm to 2 RCA cable.

This cable has a 3.5mm plug on one end and two RCA plugs on the other. The RCA plugs are typically color-coded: red for right channel and white for left channel.

Where to find these cables:

* Online retailers: Amazon, eBay, Best Buy, etc.

* Electronics stores: Best Buy, RadioShack, etc.

* Audio/video stores: Specialty stores that sell audio equipment.

Note: The quality of the cable can affect the audio quality. Look for cables made with high-quality materials like oxygen-free copper (OFC) for the best sound.
