When I was discussing my purchase with Mike Gilkison at Zenclosures he advised against the upfire box. He claimed the reason they sell that style is only for fitment issues with larger/more subs. (if I understood him correctly). He advised the backfire for sound quality.

Aah not good... :(
I use the Z as a daily driver, I'm afraid the sub will go thru bad times if its rear facing.. do the grilles snap on easy and fit well? Any links to where the JL 10w3v3 grille is available that people have used?

You high or something? I said that the only 12" option was in upfire of course you can get 10" also in upfire. If you can get 12" why wouldn't the smaller size apply also :shakes head:

Ya right zenclosures is a great manufacture and great quality of boxes.

I'm thinking about getting the zenclosures. Rear fire for two 10's OR upfire two 12'. But one thing I am worried about is not seeing out the back of my trunk. Which of course I am sure, the box takes away from vision, but how much really?

Can anyone post up some picture of what the box looks like from the driver seat, looking out the back with your head turn, or through the rear view mirrors? Thanks

The Zenclosure does not block the rear view at all with the rear fire, upfire not sure about.

I have a dual 10" zenclosure rear fire, with a brand new covering installed.

The quality of the carpet Zenclosure uses is the lowest quality on the market, I took it all off and replaced it so I could sell it.

Zenclosure may make decent quality for the wood, but fall down totally on the finish quality. I for one would never buy another one, better to spend your cash on a custom enclosure with a quality finish.

I thought you said you build your own stuff so why would you even buy one to begin with? They are great dont alk bad about one of our sponsors.

Well like a bunch of people on here I wanted to avoid the process of building an enclosure from scratch, to do it correctly it takes some time as you should know. I thought the Zenclosure based on your recommendation would fit the bill nicely, granted it sounded good but the crappy covering is not something I could look at everyday. For the price of the enclosure over the cost of using a slightly more exensive material to cover it is unexcusable, they would have a real nice product if they used a better cover. And not completely covering the entire enclosure, like how much $ are saving there. You can totally notice it if your looking in from the side window.

When purchasing a product using forums like this are very valuable. If no one gives an honest review then what's the point.

The latest creation, I have tried several designs trying to maximize bass and minimize space. This pounds the hardest of all the enclosures I have tried so far, and allows me to utilize my hatch area still.

For those who are concerned with the standard box and rear visibility, I have these amps mounted on the back and the glass does not get blocked at all.

However, I may consider the upfire and step down to a single smaller Class-D amp in the future.

How did you route all your wiring? Are you satisfied with the carpet used on the box? How many watts are sending to the sub? If you switch to the upfire are you going with two 12s or sticking with one?

The box I have is custom designed prior to Zenclosures, so I cannot make direct comparisons. As long as you don't do what I did, which was use lots of masking tape to do measurements and whatnot, you should be fine with the carpeting in general.

Underneath the box, it does not eat up the entire trunk space. The sides are free to hide wires. I routed power to one side, and audio on the opposite side to minimize interference. I routed wiring to the rear through the center console. Again, audio on one side and battery power on the other. The grounding wire was connected to one of the bolts in the trunk area keeping it short.

Right now the NINE.2 is bridged to the sub, and it is rated for 400x1 at 4 ohm. I don't bump my music that hard, but it's plenty of power. With my 350Z, I was pushing 150W to a 10W3 with no problems. However, stepping up to 400W delivered cleaner and more punchy bass at similar volume levels.

For the next setup, I may move to the single 12" upfire box and switch to a single Class-D 4/3/2 amp to power the front speakers and sub. It's nothing too wild, but with the sub right behind my ears I'm pretty sure I can enjoy bass at comfortable listening levels.

i'm running a custom box with an up firing 12 and it works very well. i will how ever be switching to 2 10's, still up firing in the next couple months.

I think the quality is great, I have the single 10 rear facing and think it looks great. here are some pics that show the finish and the view out the rear window and in the rear view mirror. as you can see there is no obstruction of view.
