Hello pakwheels community, I have a Honda Civic 11th Gen and I am planning to update the sound system to get high quality along with decent bass. I have no knowledge about how sound systems work, but I do know that people usually install amplifiers and bass tubes, but it takes some space as the bass tube is probably kept in the trunk (if im not wrong) and the amp under the seat usually. My question from experts is that what do I need to do in order to get great quality sound like we do in high end vehicles. And do I have any options if I don't want to take a lot of space and want to replace the speakers that already come with the civic without adding any amplifiers or bass tubes? Many thanks!
