So I'm a first-time user here and I own a 1963 Nova with pretty much original everything INCLUDING the fact that the original owner ordered it WITHOUT a radio (so there is a rare factory-installed delete plate where the radio should be).
I'm in the process of installing an amp either under the seat or in the trunk and two 6x9's in the the rear deck (saving the original rear deck so I can return the car to stock if ever needed) and I'd like to simply run RCA's from the amp to a headphone jack for my iPhone for music. This seemed pretty straight-forward and simple.
Then I got to thinking.
The new iPhones/iPods have TRRS jacks/cables (and not just standard headphone TRS jacks) and have an additional ring on the jack end and an additional wire inside the cable so they could add the volume and play/pause controls to the headphone cable. MY QUESTION IS can this additional ring be used to complete a circuit (or cut a circuit) and flipping a relay to turn the amp on (so the amp turns on and off when the iPhone is plugged in)?
It seems simple in my head, but I've never seen it done (but I also don't deal too much in car audio).
Anyone seen this before?
Thanks in advance!
Oh, PS... If anyone has any amp/6x9 suggestions that would be good keeping in mind I'd have no EQ controls in the car that would be also great!
