Best sealed subs for impact tight bass and rock?

If you're going to spread the subwoofer out with 4 or more small cubes, you've got to take into account cabling going into or coming out of the speaker outputs or amplifier terminals. Connecting them and having like a 4 way splitter to connect to those 4 small boxes. These joints needs the exact reading going into the pre-amp inputs from the radios. So that it will be all in unison. Very much technical and tricky here. I'm serious. If you're already handy with technician stuffs, no problem. If you're not that good yet, this won't work. So watch out on the setups.

What about the rectifier downstreaming the decibels into the final ohm load and causing crosstalk with the rca cable upload signal?

That's good. The thing is finding a like 4 way splitter. Giving the exact reading coming out of the speaker outputs. I'm think he wants a big concert in his van or truck. So spreading things out. 4 small boxes. Wow. Nice job. A miniature size concert. I think that can be done. They're also doing this especially radio stations that make this into a PA system. On the side of the road. But really loud stuff.

There's a huge difference in sq between a prefab ported and sealed box. That prefab ported won't have the range or go as low.

I'm thinking you haven't heard proper subs in a sealed box. Not all subs do well sealed but I promise you my sql-15's have a lot of output sealed.
That's completely possible. I haven't used a sealed box by choice since i first tried a ported box as a teenager. I think of sealed as outdated technology.
