15 amp vs 20 amp

@ghdprentice, if using powered subwoofers, would you run those through the power condtioner or the same (or different) line as the amp(s)?

Thanks for input.  I took the power cable for my amp out of the conditioner and straight into the wall and sure enough it did make a difference!.  

Hmmm. Good question. Ideally, a separate direct line, or if that is more than you can do, along with the amp. But, I have never experimented with adding a sub to the amp circuit. The sub is an amp… you don’t want to constrict flow. I am sure the former is best. Combining multi-Le amps will not be ideal. 

I think most subs are Class D amps that don't require as much current. 

@jea48 always makes sound technical explanations

On a side note, you would be quite surprised how few amps you really draw if you were to measure your wall outlet to the system running at a high level. In the past, a similar system to my present was drawing less than 5 amps. So, headroom is very important, but 15 amp products are not going to impede your system.

@mlapenta Yep, cables do matter.
