[QUOTE="Buck, post: 8909386, member: 591582"] I mean technically I think it'll be like large sealed if you seal off the trunk. You want to get drivers designed for IB or free air where they don't need mechanical loading / air cushioning from the box. I haven't done IB specifically but done t-lines which can be super similar with the lack of chamber loading compared to ported. What I'd do is just try to maximize cone area, find woofers designed for IB that has Fs that'll allow you to play it where you want to. Yeah I'd say you want it as sealed as possible because if it's not then the leaking bass from the trunk may cancel out the bass in the cabin. You might check out HPDE plastic to fill holes, you can buy sheets of it, or just use wood and a wood to metal adhesive, just cut the wood to fit. Seal the trunk good and the rest is up to the woofers. I'm not an expert in IB-supporting woofers but I know you want a woofer designed to handle rms power free air, which many audio woofers people use in car audio aren't specifically designed to do so. If I was going to do this as well as possible to be loud as possible, I'd aim for completely hard sealed trunk and the most cone area with the most rms rating and xmax, try to get the best combo of those.
