Finally started the install of the Giant 34-Inch Subwoofer

[tomtomjr]

If you haven't seen my earlier posts, I am putting a 34-inch / 211-Lb Audiobahn subwoofer into a Honda Z600 car. For power, I am using a 42-inch linear Power amp, plus as many Zapco 151 amps as I can fit. Thank you everyone for all the input on doing this install. I have been planning and buying equipment for years, waiting to start this adventure and now it is finally coming together. Not much done yet, but it is finally starting!!!
---UPDATE---

Today, I finally finished up the facing for the box. I knew it would look big in the car, but didn't realize that it would be this big. The speaker is really, really going to take up the whole car. I figured it would, but now that it is finally starting to come together, it looks huge. Absolutely huge. Way bigger than I imagined.
On the mock up of putting the Linear Power amp in to make sure it would fit, I have had to remove both sides of the back panels. It would not fit in any other way. And it fits only in the one place shown in the picture below. Will not mount standing up. Flat, and only in one place. Period. I was starting to think I would need a crowbar to fit it in. But after about 20 minute long wrestling match, I finally got it to fit. Originally I was going to use some US Amps VLX series amplifiers, but they are 45" long, and will not fit. (just listed them on Ebay)... 42" is going to be the maximum amp length I can use. The only way I think I could use the VLX amps is to mount a surf rack on top of the car, and put them in the rack. I am still not sure if the Linear Power amp is going to work in this though. After the box if finished, I will have even less room to work it into its mounting spot. If it won't fit after the box is built, then I guess I will Ebay it, and get a couple of Harrison 1600w amps. They are tiny, so I know those will fit.
Tomorrow, I start on building the box into the car. Not possible to build the box, then put it in. Other than the amp fit problem, it is going smooth. Will be taking the doors off tomorrow sometime to get a little more wiggle room. Anyway, just figured I would post an update. Will post another update in a week or so. Hopefully by then, the box will be built and the sub will be in. I put a few pics below. To see more pics, click the link below, then go to the "Honda Z600" Link in the albums part. If you want to see more of what is going in the car audio-wise, there is a link for audio too.

Oh wow! That is going to be superb fun

I hope your investing in enough deadening for all the panels, that combo is going to shake that poor little Honda all over the place. So I take it the install is going to be very stealth yes

It's going to move the whole car. See if you can do jumps

[tomtomjr]

Yes it is. Complete Steath system. Will even build a false cover over the HU in the dash. Nobody will know that I have a system.

On the deadening material... I built a 8x10 underground storm room 2 years ago. To waterproof the concrete, I used rolls of some material that I think will work perfect. So I kept a roll for when I decided to build. Can't remember the name of it, but it is shiny white on one side, and super sticky on the other. Peel off the backing, then stick it. When put to metal, the metal looses its ping. I figure about 1/4 roll will do the car. I did the front floorboard already, and you can tell a huge difference. Reminds me of the factory GM sound deadening material. I think it ran about $100 a roll. 4x100 ft. If anyone is interested, I will check into who makes it, and where to get it.

You just gave me an idea. Maybe I can reverse polarity to the sub and get better gas mileage...Wind power...

[roysav]

wow this is going to be a cool build to follow,keep up the good work.

It is just plain blasphemy to do that to such a nice old honda.

[bobduch]

Why did the chicken cross the road?




It got hit in the ass by a 34" sub.

Should blend well with the front stage.

Seriously though - I think you may want to add a bit more to the baffle. I'm not sure how heavy the sub is but shit any driver that is 34 inches is going to be a beast. I would at least think a quadruple baffles is in store.

Also... suspension upgrades?

[Nelson de Leon]

The baffles look small for that big sub!! With that power requirement, what kind of alternator are you planning on using...

The wall is just getting started. I will double it in thickness. Total will be 3" thick. It will hold it. I hope... I am guessing the overall weight of the box, sub, and amps will be about 500-600 Lbs. Definite need of some air bags in the rear to support the weight. Figure I will do that after the box is done. For the alternator, I have a 130A Delco style. The motor is air cooled, and the fan is a separate belt contraption. I am removing it, disabling the stator, and building a bracket for the alternator. Plus adding an electric fan in the front. The motor is only a 600cc motorcycle engine.
I even have an idea for a separate generator to run in the rear. Only going this route as a last resort. There is a space where the spare tire sits that will hold a 2000w honda EU series generator. Would be a ton of work and really don't want to go that route unless I absolutely have to. The generator would have to be completely pulled apart and reconfigured. Would take a ton of time, but is an idea if I can't get the alt to work properly. Unless someone has a better idea...

Gotcha. Yeah, my guess is 3 inches should be enough. Also, the sub is going to fit into the door opening correct? <-- that doesn't get asked very much

After I pull the doors off, and find about 3 people to help put it in, it should fit. It better fit. Guess I can use the sunroof idea if not...

[cmytaco]

impressive. a lil insane but impressive nonetheless. You should sell these on ebay

[Oliver]

Should be interesting to do !

RC with a homegrown version...

Is this going to be IB or enclosed?

Sealed/enclosed. I talked to someone in Finland that put a 34 into a Fiat. Box was too small, but still impressive. It did 147 at 55hz. I might try some porting later. Depends on how it sounds sealed. Someone on here gave me an idea in an post a few months ago about porting it out the bottom of the car. Sounds like a wild idea, but seems like it would work...

I guess you could always go with a Targa top if it doesn't fit through the doors! Then again, that car would look cute as a convertible.

Brace the magnet against the floor, it'll take some stress off the baffle and stiffen the whole assembly.

More than that, with anything this large you should use an internal frame for the basket like they do with Jackhammers. The weight you would have from adding enough layers to the front just to support it is crazy. An internal frame would be so much better. If you hit a bump with 211 lbs (at least 75% of which is 18" away from the mounting point) it will put incredible stress on those screws.

Wut bottom end???

That poor car...

[jtroy]
