After several searches for the perfect subwoofer to fit in the ski hatch of my BMW E93 convertible I came across the website www.e93subwoofer.com. This website had exactly what I was looking for to fullfil that need for base without losing my boot or trunk space since I have a convertible.
I search BAVSOUND,ebay.com and other Bimmer Website Post (http://www.e90post.com/forums/showthread.php?p=19194293#post19194293), but could not find the ultimate BMW E93 subwoofer upgrade that would give me the true deep bass thump that my heart desires. Until I came across e93subwoofer.com.
