Im from the Uk and just brought my first BMW (535d 2005) today.
The audio system I have seems ok but not enough for me. I want to amp the underseat subs but not sure I have an oem or L7 amp or none. So my question is where would the amp be located in my car?
All I know about my car because I only picked it up a few hours ago. It has the CCC IDrive computer installed.
Thanks in advanced.
