Ok, for the capacitor, I've used 47uF. It gives the most Bass, but then of course I cannot set the volume too high. It was a choice between:
1.) High Bass, Low Volume
2.) Lower Bass, High Volume
So, I picked option 1. This amp really has a very, very high sensitivity & emmits a lot of noise & ripple from the speakers... I'll have to use a High Definition Audio device for the input, because this amp will amplify the noise coming from the source too. When I tested it on my PC, I had to set the volume of the PC to 5% & it was already kicking hard... The amp is my 1st attempt & I'm looking forward to the next. I really would've liked this amp, but it's just very noisy. If I disconnect the source, then the noise are very quiet, but if I connect the source, I can hear a lot of ssssshhhhhh & zzzzzzzzz, except if I turn the volume up, then it seems to make less noise for some reason. I think my biggest problem here is the input, because seriously, setting the PCs volume to 5% is very low. {All audio devices emmit a sssshhhhhhh sound, even HDMI devices. It's very low, but it's still there. On High Definition Audio devices, it's not possible to hear the noise, but this amp for sure detects noise & then amplifies it}. I think the only thing I need to do is use some dumping resistors at the input, because even at 1% I can clearly hear audio playing from this amp {If I use my Hi-Fi, it's signal processor doesn't even detect audio at 1%}.
1.) What the heck is the difference between Class A, B, C & D amplifiers & which of them are the best?
2.) What Class amp would this be?
3.) Does anyone perhaps know of some other amp I can build that outputs 2-Channel audio between 15 ~ 45W @ 4 ~ 6ohms, maybe a circuit diagram?
