Regretted getting rid of my Cobalt 95 about 7 years ago, and found a Black Emerald 94 NA back in 2007 to make amends. Drove it from Miami to Knoxville, TN, via Tampa the first weekend I bought it. Ahh, memories.
You can check out my profile for some stereo ideas. I went with a single DIN Alpine and kept the pocket (just too handy for sunglasses). ChrisZTT did the sub box and they're amizing quality and fit/finish.
