The Pro is that I have some that I just bought in pristine condition.

The Con is that I have not install them yet.

My Standard is pretty loud already. There are loud Jardines inside the TRUCK STACKS.
She sounds like a Mustang 5.0... I love it!
Frankly, I am curious about the sound that everyone talks about re 6 into 6's..
I've never heard the sound of 6 into 6's.

Might anyone provide me a link on YouTube
where I can listen to them?
