I custom build guitar amps I was just now wondering what are the main differences between the two? Since I already know how to make guitar amps should I be able to make my own car audio bass amp? Should it not be about the same as a bass guitar amp? Anybody know anything about this? Also I have heard about you being able to send your amps back to the company and having them rebuild them for more power, would you be able to buy this stuff at electronics surplus stores? If so what all would be needed?
