So you think that zip cord speaker cable is just fine??

My Brother In Law has a set of ADL 300i auto speakers, and he wanted to see if they would still work. They only have the spring clips, so could not use my regular cables, so I grabbed a roll of zip cord speaker cable I had on the shelf to hook them into my shop system, just to test them.
Here is the roll of 14/2 speaker cable that as you can see was manufactured in Sept. 2009. That's just under 3 years ago.
When you strip this wire, here is what you get. Copper has corroded and is no longer nice and shiny. This is not the old end of the cable, but a section taken from about 6' in.

All that corrosion just sucks the life out of your music and there is no shielding to protect your audio signal from rfi.

I'm glad you opened up the can this time Doug. Tinpan can't blame me for this one!

and 22c gauge at that. the father has spoken, resume your previously consumed channel.....

Most times, this is cause by using a shitty insulator that reacts chemically with the copper:

According to my local antique dealer that green stuff is called "patina" and people pay BIG money for it.

OK guys, I'm gonna start making a new line of "Antique" speaker cables with the special "patina" ! Big money, here I come!!!!
