Audio Systems: amplifier, panasonic radio, acoustic amp

Question
I have 2 4 ohm 12" MTX's and a 1800watt power acoustic amp and every time I turn the power on it cuts out my 160watt Panasonic radio, I was wondering if you could give me some tips.

Answer
right off the bat, it sounds like you don't have large enough power and grounds going to the amp, and you don't have a 'stiffening' capacitor of at least 1 farad hooked as close as feasible to the amp. this causes a voltage drop to be seen by everything else electric. your headlights dim a little then, don't they....
