answer::if it has two speker out puts and it says together 100 watts at 4 ohms max that means,with 4 ohm speakers its 50 watts to each channel and thats all it will deliver,now with 8 ohm speakers it will only deliver 25 watts per channel. In my latest speakers ive built were for my brothers car and i used house speakers(8 ohms) in a car (4 ohms)so i built one box and put four ten inch speakers in it.which showed to be a little to much so i figured i would put a divider in the box. so it worked and it sounds pretty damn good. now i have to get an amp to push the 4 tens with .they hold about 50 watts a peace at 8 ohms which is 100 watts a peace at 4 ohms. so now im going to have to buy a 400 watt amp which is going to cost me. now if i had used 4 ohm speakers then i would have only had to buy a 200 watt amp.
now if you could email me some time then maybe you could help me with some of my questions thanks, david
