I purchased this Amp kit and then I purchased the TRIPLE speaker posts. I have a photo below.
The Triple Speaker Posts are nice... I had a concern with them... They just fit in the rectangle hole and barely fit the narrow way. I put these in my amp and it was a hair between the brass of the post and the chasis.
These are the Speaker Posts -
Here is an owner of an nice pair of amps using these speaker posts.. Notice how the outer edge of the speaker post brass is just nearly touching the chasis.. Is that a problem? Would the amp short if the brass touched the amp chasis?
I worried about this so I ended up and still use these -
I was also thinking if you had some 1/4 to 1/6" black plastic washer in the TRIPLE speaker posts you could have the metal of the speaker post extend out past the chasis...
