I'm building a boombox using car audio gear and the only problem I haven't solved is the ac to dc power conversion. I've read numerous suggestions on using an atx power supply, but some say that it is "dirty" power. So I've started looking for a 12v regulated power supply. From what I've gathered it looks like it would need to be 10-15 amps to drive the head unit. Any other ideas or suggestion on where to look? Thanks.
