Hi, i remember when i had my previous car stereo setup that my head unit would get warm alot. not actually over heat but it would be really hot and cds would come out and burn to the touch. my head unit is a 45x4 and it was powering 4 speakers. but not my sub.
my rear speakers are 160 watt max and nominal power is 40watts , i have a 200 watt amp that says it can supply 75wattsx2 channels, would my head unit be less stressed if i use the amp to power the rear speakers seperately and would the amp power the speakers well or should i get a bigger amp seeing as the max on each speaker is 160 watts?
i have more q's but i wont plague the board with them all at one time.
