Thank you, these are the answers i was looking for, but i mentioned subwoofers but they are more like midranges, i took one out of an old stereo that had 2 tweeters and this midrange speaker, and even powered by an ipod, it has good bass response. Are there any other changes that i could make to improve sound quality? And what cap should i use for bypass at pin 7. And I know that the 386 is not great, but it is cheap. Are there any other alternatives that are still cheap yet work as well?
