stereo in glove box

for power to my new radio i just spliced into the power for the stock radio . i ran a new ground to the battery to make sure i had a good ground. and i spliced into the cigarette lighter for my constant hot. so that my preset stations dont get erased when i turn off the car. you dont have to do it this way. it was just easy because i figured i wouldnt be using the stock stereo. and if i had to it could all be put back to stock.
