bye bye back seat

bj70_guy · 01-24-05, 07:26 PM

I've been wanting to get this happening for a long time. Unfortunately, about the only thing I can build is a turd, so recently I got a buddy to build me a drawer set up for the back of my 70.

Here's the main box. Note the compartments at the front for a 10" sub and 2 6" woofers...

bj70_guy · 01-24-05, 07:27 PM

300lb sliders in...

bj70_guy · 01-24-05, 07:28 PM

drawer, dividers not in yet...

bj70_guy · 01-24-05, 07:29 PM

Drawer in, begining of top in place...

bj70_guy · 01-24-05, 07:30 PM

PERFECT fit between the wheelwells...

bj70_guy · 01-24-05, 07:31 PM

Drawer out, top in place...

bj70_guy · 01-24-05, 07:32 PM

The view from behind the driver's seat. Suddenly looks pretty roomy back there!

bj70_guy · 01-24-05, 07:35 PM

First coat of marine enamel on.
When I get home in a couple of weeks I'll post the final product. Look for a CO2 bottle mount, hi-lift mount, and lots of flush mount tie-downs in the finished product...

Greg_B · 01-24-05, 07:55 PM

Way cool Norm! I want for the back of my 74!!! Please, pics when you're done, and safe travels...

Blue Bandit · 01-25-05, 10:06 AM

ooo pretty
is your friend taking orders?

Stone · 01-25-05, 11:02 AM

Nicely done, Norm! Seal up that sub enclosure really well. Are you going ported or sealed? Have a safe trip. Post up some nice foreign Cruiser pics when you get back.

Greg_B · 01-25-05, 11:03 AM

Hey Bandit...get in line! hehe...

I think there are a few people from the CC that are going to be interested in this.

Blue Bandit · 01-25-05, 11:32 AM

BTW a while back Sport Trucks quoted me on essentially the same, but metal.
I think it was $350 for the 7" and $430 for the 12" (inside height).
Have been holding back since that would put the pooch WAY HIGH and in my rear view sight line.

Derek A · 01-25-05, 11:44 AM

Cool, I gotta make one of those too, I was thinking of aluminum, but that would cost a heck of a lot more.. How heavy is that?

bj70_guy · 01-25-05, 12:31 PM

Stone: No porting in the sub box. It's reasonably well sealed, as is the rest of the box - liberal amounts of construction glue and about 200 wood screws...Maybe a bead of silicone on the inside of the sub enclosure for good measure?
Got any recommendations for a good 10" sub?

BB - The prices on those metal boxes sound awfully good - I have over $350 in materials alone in this...and about 25 hours of labour.

Derek - It's not too heavy, though we've only dealt with it in 2 pieces (top and main box). One person can handle the main box assembly easily.

Rockford Fosgate, a little pricey but well worth it, don't forget to use a Fosgate amp with it. Your sub box dimensions should be fairly close to the manufactures recomended specs, if your box volume is too large, add another sub, or port it (with a proper port).

Derek A · 01-25-05, 12:43 PM

Oh yeah, a 10" sub in a sealed box usually requires about 0.6 cu.ft. volume. In a ported box you will need about 1.0 cu.ft. Don't use the sub in a box that is too small or too big, you won't get the best performance, and my not be happy. Just my 2 cents

lowenbrau · 01-25-05, 04:30 PM

Looks good , Norm:

I'd devide the space up and add a port tube to the woofer. There's lots of good calculators like this
http://www.the12volt.com/caraudio/boxcalcs.asp#por
on the net that'll help you make that box sound really good.

If you haven't bought that Powertank yet you should spend the money on River Shiver and come and win one in our raffle.

Cheers

bj70_guy · 01-25-05, 04:50 PM

cool, thanks for the sub info. That front compartment is seperated in three (you can just see it in the second pic), I'll figure the dimensions of the sub compartment (in the middle) and go from there.

I already bought the tank and regulator (hey, needed it to be able to figure where to mount it - right?;-). I'd love to be at RS but I'll be on a friggin plane to Australia instead. Can I still buy a raffle ticket ? ;-)

gar · 01-25-05, 05:46 PM

norm try excargo for subs. there in richmond and online. gar

Stone · 01-26-05, 12:17 AM

You can't really generalize how much enclosure volume subs need...different brands require different volumes. A typical Pioneer 10" sub requires 0.6 cubic feet of volume in a bandpass box, and between 1.0 and 1.2 cubic feet in a sealed enclosure. So you've gotta make it for whatever sub you end up with to maximize the sound. A bead of silicone along the seams on the inside of the box would be great.

Yes, Rockford Fosgate makes some pretty nice subs...they have several lines from cheaper to competition quality. The Punch seems to be a fairly decent buy...I ran two of those in my Corolla in high school, and they thumped real hard (800W RMS going through them from my amp). I then "upgraded" to a 15" MTX running 1000W through with an Epicenter, and that REALLY thumped.

People could hear it coming well over a block away. Probably explains something about my hearing loss.

I have a tame system in my BJ74 right now...just something to give me the full range of sound to my music. I have an Alpine Flex5 amp and a Phoenix Gold 10" sub in a sealed box. Not really pleased with the Phoenix Gold sub, so I'll probably end up replacing it with something else. I want my old JL Audio sub back from my brother...but I don't think he'll give it up.

wesintl · 01-26-05, 09:33 AM

Awesome it looks really good Norm. How high is the box and did you use 3/4 ?

Radd Cruisers · 01-26-05, 10:02 AM

Good thing I kept all my reno tools, out comes the Delta Uni saw(Norm Abrams of this old houses shop saw).

Biscuit jointer, I like the screws but prefer biscuits for strength.

Looking good.,

Rob

Thanks, it's a combination of 3/4" and 1/2". I can't remember exactly how high it is - I think it's 11" or so.

Blue Bandit · 01-31-05, 12:18 PM

oops from Sport Trucks it was more like $430 for the 7" and $550 for the 12" (inside height)...

BTW tuffy prices are US$423 (item 58) and $453 (item 63) ...and they fit '40s

bj70_guy · 04-13-05, 10:28 AM

I can't believe it took 2.5 months to get back to this project...

anyway, it's in. Just have a few final things to finish up - a few more tie downs, the mounts for the hi-lift and the hold downs for the CO2 bottle, but this is basically it.

bj70_guy · 04-13-05, 10:29 AM

dividers in

bj70_guy · 04-13-05, 10:31 AM

drawer slides seem plenty skookum...

Stone · 04-13-05, 10:53 AM

Hi Norm...can't see the last few pics for some reason.

By the way, don't you think that a lot of people would be interested in your project in the International Tech Forum? That's where most of the 70 series owners hang out. Let me know if you want me to move it.

Cheers,
Stone

Aahh...finally loaded up for me. Looks good. You going to lay carpet on it at all?
