Yes, the new sub sounds much better than the old at modest power levels. But with the amplified Boston A Pros, it sounds so much richer and fuller at higher levels, and becomes a real bummer when the sub can't keep up because the rear quarter panel becomes a giant baby rattler.
I'm trying to decide on two options:
1. 2 - 8", 2 ohm BA Pros in the storage bin, fiberglass tub with MDF baffle board. I'm going to let a shop do it because I've learned from experience that the very first time you work with an unfamiliar medium, it will inevitably become a practice-project, and I don't have the frustration tolerance to deal with that anymore, especially for a (hopefully) one-time project.
2. Custom fiberglass enclosure molded to "blend" as aesthetically as possible into the rear right corner, next to the factory sub location. A single 10" 2 ohm BA Pro would sit in there instead of a pair of 8s.
I either have to loose the storage bin, or some rear cargo real estate. I'm leaning onthe storage bin because it will be a stealth approach. Why not have a fiberglass enclosure in the original sub location? Its been done before, but I feel it's too shallow and awkward of a shape to squeeze the full .5 cu ft I need out of it. Plus, I still need a place for the medium sized amp, and if I put it in the storage bin, I'm losing full use of that compartment anyhow, so I might as well stick two 8s in there, with the confidence that I have the right enclosure specs for it.
I'll be mounting a mono amp (why mono? More sub power for less space, compared to bridging a 2 channel) on the inside of the quarter panel, to the rear of the subwoofer opening, with the cable inputs near the hole.
