Connect with RCA Cable

Stereo amplifiers with RCA inputs have the best audio quality. Here is how you can connect through RCA cables

Connecting iPhone with 3.5mm port

If you have an iPhone with a 3.55mm headphone jack and an amplifier with RCA ports, you can easily get an RCA cable with a 3.55mm jack. Simply connect the two RCA connectors in the ports in the stereo and the jack in the iPhone. Remember that the ports are color-coded, so you have to plugin accordingly.

However, if your amplifier has 6.5mm ports instead of RCA ports, you will need 6.5mm to RCA Adapters.

Connecting iPhone without 3.5mm jack port

New iPhones have a lightning port instead of the 3.5mm headphone jack port. So you will need a lightning adapter. You can also use an Apple lightning dock to connect the iPhone to the stereo amplifier.

In any case, when using RCA cables, do not keep the iPhone volume too high to avoid any distortions.

Connect with Bluetooth

iPhone has built-in Bluetooth, and if your stereo amplifier has Bluetooth, the two should connect without a fuss. However, if the amplifier doesn't have Bluetooth, you can use a Bluetooth adapter.

The Bluetooth adapter can be plugged in the audio inputs while it receives a signal from the iPhone via Bluetooth. You can use RCA connectors or a digital optical cable for this purpose. Bluetooth adapters may require batteries or USB charging for power, while there are others that can be powered with a wall plug.

Few good options here are:

Connect with WI FI

You can also use wireless adapters to connect iPhone to the amp. They provide the best sound quality and offer more range, unlike Bluetooth.

If you are looking for an amplifier with built-in WI FI, consider getting one with an Airplay. While it provides the best sound quality, Airplay works only with Apple products. There are other wireless adapters too that can be used with Play-Fi etc. Just check the compatibility of the wireless adapters.
