I'm really interested in doing a Hukuna-style subwoofer install in my 93. I know clearwater used to offer a panel, and carbon miata now offers a panel, but both only fit 6.5 in speakers. I lean towards getting a panel over just cutting holes in the existing metal because the panel seems to point the speakers toward the driver and passenger more, which seems like it would work better in terms of sound quality (instead of just facing upwards). Anybody done anything like this? I need inspiration!
