hey guys its me again. anyway i went to school and we were given a new project. it is something related to the issue "safe and secure". i decided to make a mp3 plug in speaker audio amplifier circuit. it is a speaker that plugs into the mp3 instead of headphones. i got the plug bit and soldered wires to it, then i amplified the signal through a single transistor (bc548) and the speaker i am using is powered off a different power source. then i connected the plug bit to a small radio and tried it out. at max volume there is considerable distortion and it isn't very loud. i listen to hip hop and rap and this music has lots of bass which increases the distortion.
how would i decrease the bass of the output signal to decrease the distortion and still amplify the signal to make it louder? for the amplification should i use a darlington pair or is there some kind of special transistor that does the job?
is there any other way to make what i want without messing around with the bass and treble levels?
