I installed a car stereo a few months ago and it seems to forget all of its settings whenever it loses power. The stereo the car came with didn't have this issue. I am familiar with electronics so I am assuming it needs a constant power source to keep the memory in-tact, however the ponytail connector is different than that of my cars, I had to splice wires to get it to work. There are 2 power cables that supply power and I have tried both and neither seem to do the trick (only 1 combination works as the ampage is different).
Is there a way I can possibly rig a small battery to one of the cables or something so that there is a constant power supply going to the radio? Or perhaps the battery in the stereo itself (if it has one) is dead?
The car is a Sukuki Swift 2006 plus
The stereo is a TKO BH-MP180
