So after trolling through this forum looking for information and doing research after research on parts and ICs and how it all works, and finally making my own little circuit i feel pretty confident enough to make a 2.1 amp to incorporate a sub into my next project
But something i do not understand is how i would do this, i have a number of ICs hangin about, one which just happens to do just that is from a board i pulled apart, its part number is,
4558d jrc sum 6b29w, there is 2 other ICs on the circuit but im sure this is the one for the amp,
However i understand how to make a normal mono amp and how to use two to make a stereo setup but something i do not understand is how i would convert one to drive a small driver as a "sub" only small but i only need small as it is a tiny setup with 2" 4 omh 2watt speakers, Hench the need for a sub as there is no bass at all.
So does anyone any advice on what i could do to make only low frequency be sent to the sub? thanks
P.S - i learn t how to read diagrams so if you have one i can look at i should be able to read it and work out what i need to do
thanks guys
