BSW Mid-Woofer Install Question

[Scott in Cincy]

I'd call BSW, but their phone service seems to be out ( )

When you install the midwoofers for the doors, it seems that there really is no positive and negative for them. According to the directions I got, there is a small connector and a larger one (larger being positive). However, the connectors I got are both the same size.

So, I went about connecting the copper wire to the positive terminal, and the silver wire to the negative. Is this right? Just for giggles I reversed them to see if it made any difference and it did zippo...

Also, the directions state that the positive is on the right, negative on the left. Is that when you're looking at it from the top or the bottom? (Doesn't say, I assumed it was from the top).

One last thing, has anybody found a good tool to remove the vertical sunshades? I have bent two small screwdrivers trying to pop them out.

Thanks!
