Ok,
So i have been searching for past 6 months since i bought my srt-6 convertible and i cannot find any good and viable solutions
I looked in to fitting the sub behind the seat, but that is not very good solution. Right now i have two 6.5" subs which are rubbish.

The other issue that i heard from Alpine, that they had on one of their show cars is that if you fit the sub in the trunk it could mess up the sensors for the roof,so it wouldnt open or close

Does anyone has any ideas what can i do?
