Glenn's 2013 Scion xB Ground Zero centered build.

Not sure if you bought the equipment already but couldn't you go with a bigger midrange?

^ doesn't give up anything other than high-end extension... It's shallower too

Unfortunately we do not have any of the 4" in stock. At the time of our order from GZ they did not have them in stock. We will be bringing in a lot of the raw drivers on our next order , providing they are available.
In the mean time we do have both the nuclear 80sq and the above mentioned plutonium 80sqx.

Welcome aboard, Brandon.

I did not consider that one for a couple reasons, the stock status being the most obvious. I also noticed the recommended frequency range with a low end of 250. Since I am going with under seat midbass, I wasn't sure if I would need my midranges to play lower than that, so I opted for some the 80SQX's. Of course if the upgrade bug hits, I may start there...or with the midbass....or.....well, you know how that goes.

Welcome to CAJ Brandon, glad you could swing by and check us out. We aren't as big as other sites, but neither were they at first LOL. Something that just popped into my head, both CAJ and GZ USA are at the ground floor of something big. Might be a good match!

That's some sweet looking gear. Look forward to hearing your impressions on all of it.

With the natural gain in most cars being around 250Hz and 400Hz, you don't need your midrange to play that low
In most of my installs, I had to kill the 160Hz-400Hz range with EQ - now I just cross around 350Hz-400Hz

Never used an underseat midbass so I don't know how high and what kind of boost or null it can create - eager to see some measurements

The biggest issue I see with midbass under the seat is being able to localize it from tactile feedback. Of course there's always ways around that though.

Sub'd... Glenn's builds are always impressive

I'm excited! I'll definitely do as much as I can.

Ok, couple pics of non-GZ equipment.
