my pos headunit panasonic that came with mt car has 2.5 volt sub outs I am getting a new one and was wondering what the difference will be in my sub's performance with a 4volt or 6.5 volt
I know it's better, but the cd player I want has 4 volt but if 6.5 is the way to go I have another one I like just wanted to know if the 6.5 volts is going to make a BIG difference in my sub's performance
