Sweet, I'm very interested at taking a look at the final product. I've always wanted a ZEnclosure but still wanted to keep my rear cargo cover and keep my spare.

Sub Box Picture
 

See picture of my fiberglass sub box and false floor. The entire piece wights approx. 6 lbs. The sub box portion is wrapped in sound deading material so no rattles are heard. The finish is black gelcoat with a mat finish that looks similar to the finish on the plastic panels in the 370Z. The false floor lays on top of the rear hatch panels. This sub box piece stickes up approximately 1" above the rear hatch false floor.

The cut-outs seen through the speaker cloth are for the signal processor and access to the amp. The right side just poking out from the bottom is the bottom of the sub box. This is a one piece design that drops in the foam piece area of the rear hatch.

This looks nice. Interested to see some pics of it installed in the car.

Also interested. Can't wait for install pics

Sub Box Installation Pic
 

Here's a pic of the fiberglass sub box installed behind the strut bar.

The sub box is basa-core fiberglass composite, black gelcoat finish with a leather like grain pattern. The sub box houses the bitTen signal processor and amp and covers the empty foam piece located behind the strut bar.

I'm interested. Is that the 6.5 version?

I thought you had mentioned a 6.5" speaker version.

Fiberglass Sub Box
 

Others have inquired about having two 6.5" subs which could be accomodated. The maximum size that would likely fit in an upfire mounted configuation is 8" depending, on the interior volume needed tuned for the specific sub's acoustics.

Looks great, was hoping for an update. How's it sound with that placement?

Sounds good...now I have to add some more sound deadening material to the driver's side panel under the small side window! :tup:

Here is my setup, I was going to have bigs install it all for me because he's awesome. But I just couldn't get time to come down for him to install and I couldn't handle listening to the stock radio anymore. The soundstream amp turned out to be a tad taller that I would have like. But you still have room for a sub enclosures. I also made another carpet for the rear hatch so i could save the factory. It's not 100% done.


2 6'5 Polx db651 2 Pioneer TS-SW841
SOUNDSTREAM STL6.620 under the plate.

So like others I wanted to keep weight down. I used a 3/4 chunk of birch plywood for the plate. The amp is mounted on bracket cut from the same material and bolted to the two 7/16 bolts coming up through the floor. Smack dab in the middle of the space. So right now With the 3/4 bracket and the height of the amp I only have 1/2 between the subs and the amp. I may make another bracket from some thinner material, or I may just make the sub enclosures out of some epoxy fiberglass I have left over from working on my scarab. So as of right now they are all running free air. I've been keeping it turned down till I get time to enclose the subs. I'll leave the 6'5 running free air I imagine. If I remember right, I'm not sending anything lower then 80 hertz to them. Unless someone tells me they sound better then they already do enclosed. 105 bucks is cheaper then I thought it would have been. I have 15 bucks in material and 20 minutes in time on the one i made. So not all bad. I just need to finish the edges.

Is the sub plate paint finished? My sub box is only 1/2" thick (two 1/4" basa-core (coremat) sandwich constructed with fiberglass cloth on both sides with a fiberglass middle core). It is strong enough to support one 8" or two 8" subs and and amp. The sub box and plate weighs in at 6 lbs. I do not think most here know of the construction technique I am referring to in my sub box.

Off-topic: Is your boat a 38 foot Wellcraft Scarab? I had one myself with twin supercharged 540 big block engines back in the day. Nice offshore boat. :tup:

I was going to weigh the plate before I mounted the speakers but forgot. The plate is done for the most part. All I did was wrap it in the same felt I made the truck mat from. I want to say the plate weighed right around 5 pounds.. The bracket for the amp, maybe 2 pounds. I went with the 3/4 plate to give me just a tad more room for the amp and so that I could keep the 6'5 speakers out towards the outer edges. The speaker grills made them just a tad to big to fit.



Monster boat man... Mines only a 32ft with twin 454 magnums. Crushing waves is the best... ok maybe more like skipping across the top heheeh. I recently sold my Raptor, and the scarab is next. I love boating.... But man... gas prices are melting a hole in my pocket. A guy down the road as a 44ft with triple 502's... I can't even imagine... But if you have a 150k+ boat you probably don't care.
