First I would like to thank dibs, essam, zerochief, and everyone who contributed to the previous threads on custom sub boxes for the X5. Reading through those threads has saved me some time and money. My wife was very disappointed in the factory system when we picked up the X5 in Oct of last year. Her e46 328is had a nice Harmon Kardon system and she wanted the truck to sound similar but it was lacking in the bass department. First thing I checked out was the obvious JL and BSW stealthboxs but I just couldn't see myself spending that much money without researching other options. I remembered seeing dibs thread on the design and someone contacted ED about building it, so I decided to do the same. I got in contact with Brett at ED and told him what I wanted to do and he said no problem. I received the sub first which is the 11Kv.2 model and just looking at I could tell that it was a good quality subwoofer that was perfect for what I needed. Then I received the box a couple of weeks later, which was nicely finished will black paint, did a test fit and it went in perfectly.





Right now the sub is installed in the box and since its dual 2ohm I have it wired for a 4ohm load and this thing sounds amazing. I'm waiting on the speaker level input wires so that I can install it in the truck, but I do have it hooked up to my system in my e36 328ic and it bumps. I have a pioneer amp running 380watts Rms @ 4ohms that will power it and when the install is complete I will upload more photos and details.
