How to plug my iPhone into my tv for the volume to increase?

Okay, I have a flat screen tv and I want for the volume to increase on my iPhone. BUT I'm going to use pandora to listen to music not my playlist. Is that possible? Please answer. Ty.

A lot depends on what TV you have and what the Pandora interface is like; (they are not all the same) but usually Pandora has its own volume control also the TV has a volume control you may also be able to download an app for your phone (maybe not depending on TV) that will include volume control for your TV but it would be a separate app from pandora meaning you could not use both apps at the same time you would have to switch back and forth if your using pandora off the phone… If you have a smart TV then the TV itself may have pandora built in; in which case you could use the pandora app in the TV and the volume control app in the phone at the same time… If the TV will let you do that… Some TV's when in smart mode will not recognize other apps or the phone but most will…
