I own 2 Harman Kardon Signature amps...a 2.1 & a 1.5.


They both have puny ungrounded power cords. The 2.1, which has the most current draw, has the smaller cord (beyond my understanding as to why).


I know for sure I am going to install bigger cords. Should I just replace the 2 wire cords, or add a sheilded 3 wire cord & ground it to the chassis? If the later, can someone provide some links with pics as how to (PROPERLY) do so?

A couple of thoughts:


If they needed a ground, they'd have come with one.


You can't judge a wire by it's cover; what's the conductor gauge?


For a ground, a separate single wire works as well.



Okay, three thoughts.

The smaller wire is 18g(for sure), the larger is 16ga(or 14g.).


I want 12g. for both.

They're good for about 7 and 10 amps, respectively. I'd go with, say, 14-ga. wire, but I'd experiment with a temporary ground wire first; you might get loop-induced hum.

Since they're noise free, I'd better just stick with larger 2 wire.

Agreed; if it ain't broke, don't fix it.


Do, however, keep the polarity the same.

No doubt!


Thanx!
