The draftsperson at my work used to have a career as an audio technician, and I asked him for his advice before making the modification. He highly recommended using non polarized caps, but conceded that they were more expensive and harder to find than polarized ones.

He then told me that I could get the same benefits by using two polarized caps placed in series with each other. The caps should have their positive terminals wired together, and the speaker wires going in and out of the negative terminals, so the wiring should look like:

source -cap++cap- speaker

When using two caps like this, the uF rating should be doubled, so I used two 470uF caps for each speaker. These were available at Radio Shack for a little less than $6 for all 4 needed for the job.

At first, I thought the sound was a little "tinny", but then I adjusted my audio settings. Now I can't believe how good the system sounds. The doors don't rattle, and the bass from the subs just thumps!

Two thumbs WAY up!
