Ok so when the car goes thru its glow plug cycle my stereo and lights are starting to dim alot, the stereo turns off and on like 6 times during the whole glow cycle. This doesn't happen when the glow cycle doesn't come on like after the car is already hot so the glow plugs dont light up. So what could be cauing this extra strain on my electrical? Obviously its in the glow plug system but what is it?

is your battery weak? Sounds like the current draw is dropping the voltage slightly below what the radio needs to stay on

I will check the battery but the car starts with no problem what so ever.

I would check and clean all the pribcipal grounds. The one from fender to battery and the one from body to starter first. Or test by jumping from the n egtive battery termilal to a good spot on the engine with a battery jumper cable to see if it is one of those grounds.
