Car stereo turns on and off?

I've bought a Honda prelude 94, i'm trying to install an after market stereo and when I attach the cables to the back of stereo it lights up but as soon as I press "source" to switch to radio it lights up and off… And the antenna aerial goes up 2 cm and down and it repeats.

I started to wonder when in 2004 the 2005 Honda Element first came out.
