I have a problem with my car, my in-dash stereo tv?

i did the wiring its the first time this happens to me ive done other cars but i havent gotten this problem, i have a 1997 cobra and i put a new motor etc and now i worked on the audio but when im hearing loud music my screen starts to get blurry and it does it to when i go at a fast speed. and when i accelerate very fastmy stereo shuts down and turn back on. what is it causing it?
