Hello, I have a 2001 Honda Civic coupe that I would like to add a subwoofer too. I don't want a big box laying around in the trunk like everyone else does. I have a few spots in mind but people say they aren't good ideas or spots. I don't know much about car audio but I know a good amount about home audio. If you would like to help, let me know and I'll send you more details regarding my placements I had in mind. Any help will be greatly appreciated.
