sometimes when i blast my system the headunit actually turns off... is it because its taking so much power or what, all my stuff i got is at the bottom, it has done it 2 times since i had it ( few months) dosent do it often just dont know why it happens

 

Sounds like something is messed up with the wiring. My Alpine did this in my previous car. I pulled the unit out and discovered some pinched wires...Might wanna have a look-see.
