Upgraded the EPS system in my d with a pair of Jehnerts under the seats and a Morel Ultimo SC 10" in a homemade epoxy glass enclosure in the trunk. Powered by a JL XD 400/4. I was planning on getting some (better) matching carpet but just got tired of looking at 'glass. Definitely improves the low end but the EPS system still needs a bit more EQ work which I plan to do with a MiniDSP. A Zapco DC amp would have worked better but I already had the JL sitting around without a home.
