I was driving yesterday when I heard a SUV bumping some clean and loud bass. Made me think about the loud bass I used to listen to in my car. I miss those days.
I don't want to tear my current car apart to add subs so I just have to live with stock sounds.
Where there's a will there's a way, if you have one of those weird shaped junk stock HUs that can't be removed easily you can run everything from an ipod or better portable player, there's also SA-8s or DC M3 8s which will fit almost anywhere without disturbing anything.
