I bought a jenseng 7" am/fm/cd/mp3 player etc. not to long ago for my car..which is

a 92 pontiac sunbird.. what i'm wanting to know is....why the screen flickers on my 7" flat screen jenseng stereo system when I have my shitty little system going...my system contains of a ..Lightning Audio Amplifier...two 10" Subs in a concealed box in my trunk...two 6x9's ...and there are two other rather small speakers in the front which are not connected to the amplifier...Thanks.

Could be lots of things like a bad ground , alternater Noise, or others ...also I have never heard of that brand but I am assuming it is Chineese or Korean in make ???
