I try to keep my car as light as possible (drag + autocross). However, I feel my music lacks a lot without bass. What are some ways I can add a decent amount of bass without adding too much weight to my car? As in, the LIGHTEST way possible? I understand I could just remove the heavy stuff when I don't need it, but that's too much hassle lol. I'd rather just have something small and light all the time.
