Just an FYI, I've finally had good opportunities to finally listen to my Eisenmann Race at partial and full song with windows fully down and in my case, moonroof open. I had mine installed late last October and the weather has finally been beautiful. I gotta say I don't know why anybody takes these off and sells them! It sounds amazing with the windows rolled up and it's 2x's better with all windows open. Just the right volume and fullness/robustness. Any louder though and my old man ways would insist on something quieter but this is heaven. Amazing, just my .02 cents.
