Here's what I finally did for mine.

After installing the mopar sup (see thread below) I was a little disappointed with the results. It seemed to flatten out the bass in the front doors while causing a boom at a very narrow frequency out of the sub. I went over to an audiophile friend for opinions and advise one Saturday. To make a long story short we found the polarity was wired backward to the speaker. The terminals were clearly marked + and - but the red wire (I'm assuming red means positive) was terminated on the negative terminal. After unsoldering and re-soldering I did notice a big difference but still not a broad range. After surfing around the Crutchfield web site I came upon a product they sell in the Sub-woofer accessories section. Basically it's polyfill like you would stuff pillows with. I had some Wal Mart brand poly fill left over from one of my wife's projects so I figured what the heck. I stuffed in as much as I could without covering up the amplifier. After sealing it back up I had to turn the bass all the way down. To my ears it seemed to increase the range of the system and the front speakers sound much fuller too.
