love single sub setups, look forward to updates

 

Well unfourtunitly when I bought the SMD 18" it was perfect when i received it

but after setting in my garage for a couple weeks I ordered a new gasket and whe I went to replace it t....and this is what I found

OF COURSE "NOBODY" in my house knows what happened !

 

Your "first time powerpoint diagram" looked fine to me.
Where are the 8's for the front going?
Those PHD comps, are they the silver carbon fiber cone ones?
Another member of the 1/4 million mile club, congrats! arty:

 

Thanks the power point was fun figuring out

The 8's are going in the doors in place of the factory 6's so Yes I will be making some custom door panels ...That will have some carbon fiber mods :thumbsup:

yeah it amazes me how good a car with a 1/4 million miles runs :nod:

Good luck. I had an e46 coupe I did up. Dont know if you have enough airspace for an 18 though.

Smd 18's are built for small enclosures 4-7cuft. max ported , so if I build it to be a little more efficient and i have roughly a max of 7cuft. before displacment I should be good :thumbsup:

Since the basket was broken , I disassembled the Sub to replace it and was un-able to save the cone and spiders but I did salvage the coil , I would of rather bought a basket and a drop in re-cone but after numerous failed attempts to get a re-sponse from the only place who can provide these , I have decided to move on and build a custom

I had an extra Blue 18" TI basket laying so first thing was to modify it to fit since the SMD basket as you can see in the pics has a different bolt pattern and the larger opening

I drilled the holes for the exact location need to match the OE basket mounting

opening the pole area hole , I know this problaby looks crazy but the end result turned out good

Pic of my SMD v1 motor

As you can see the center bore turned not too bad

Basket mounted ! I kind of like the looks of the Blue basket

Just wait till you see the Cone I have for this beast :thumbsup:

 

I have a good feeling I know what the cone looks like...

 

Yes Sir :nod:

Niceeeeee! Looking good man...

Thanks Bro!

that cones going to be legit

like the build

Yes Sir! you can say it is LEGIT...verlyhappy:

I'll post a mock up pic real quick ...I have my cable for my direct leads I'm waiting for to put it all together but a sneak peak wont hurt!

 

Niceeeeee! Looking good man...

 

that cones going to be legit

like the build

 

did you go through fixmyspeaker for the longer former?

 

I'm actually using the coil I salvged from it , but fix my speaker said they could extend one for me at a extended price ...basically it's putting two coils together which I've seen done before so it would'nt bother me to do it my self if needed , the OE coils are also two seperate peices held together with epoxy and nomex

It's a 9" long former total

 

Till you see these cones in person it's hard to visuallize the size of the surround on the 18" Z.v4 cone

Here's somthing to scale the size of it here's a quarter against it

 

I presume aluminum coil? hardest part about reusing coils is resoldering to the aluminum leads if you cant reuse the original solder point

 

What I was surprised to see was there really wasn't hardly any solder used. ...the leads where held on more by CA glue I literally unrolled them but have plenty of room ....the actual coil leads where long and folded back down in between the spiders

 

I hate solder aluminum even when I have the correct stuff. Rathet just order my coils with the cooper leads instead.
Whats the WW of the coil Robert?

 

I wrapped it in non-stick painter's tape so I wouldn't scratch or damage the coil

 

Cool build bro!

 

I am def interested to see the 8's going in.

 

Lots of miles on BMW, original engine?

Sent from my eyefone.

Yeah a little .... 240,000 mi. but still running strong :thumbsup:

Tranny?


Sent from my eyefone.

It all depends ...I have a built 4L60E ready to go ...but a T56 is preffered but are getting hard to come by for a decent price doesnt need a full rebuild from people bashing the gears


It all fits in good seen tons of people on the web and youtube with LS1's in them and there's a company that actualy makes a kit if someone's not in to fabricating

 

any updates?

 

Getting ready to give this thread a re-birth ! Lots of changes overtime and getting ready to kick this build off!

 

YES, lets see some interesting stuffs

 

I've got lots of interesting stuffs planned , especially with the use of more than few Items you made me :nod:

Let's just say a 2 18s B pillar wall is coming :thumbsup:

 

do it do it do it do it do it do it

 

Ok, so I have been working on a part of the build in my spare time that is actually time consuming and experimental but will save me a ton of wight and cash :nod: What testing I have done with them the results have been really outstanding.

I was originally interested in using NimRods because of space, weight , and the good feed back I've heard. I did some research and found these cheap enough that if the experiment was a total failure I would just resell them and get my money.

Cheap enough I got 40 of them

Just wait till you hear what these are out of :rofl: some of you may know already, these are actually Honda Hybrid NiHm battery cell sticks they sit at average 7.5v and 6.5AH each and you can buy them new at $80 each or like I did 20 for $75 plus shipping used. I didn't want to buy new ones because this was at first just an experiment and after researching the used ones are usually good and the bad ones can be easily brought back to life. The place I bought them from doesn't bother with the time of DSCH/CHG cycling them they just pull all the cells out at once and install new ones, and remove the temp sensors and sell the used ones.

In my build the audio alternator and battery are going to be kept separate from the rest of the electrical of the so the higher voltage 15v+ when 2 sticks are combined will not effect the car and will give my amp section the much needed juice.

When received I metered each one and in all the pics you see these are at resting voltages from when I received them from the seller. I have actually had them up to almost a little over 9v so I could see someone charging them to a 18v charge with the 2 linked easy

I bought a small piece of all thread and tighten them up for good contact this is what they look like naked I bought a 40ft. roll of white shrink wrap for them so they will look fresh when ready.

I've done several multiple over 50amp load tests :evil5: (and YES with a clamp meter used) on the individual 7.5v sticks for 2 minutes bringing them down to 7.24v and they would bounce right back so I would say this experiment is definitely working for the good :nod:

 

Looking good so far man keep up the good work

 

Thanks ! Just wait till you see what the bank of these is going to look like I already sketchup'd a rough draft and it going to nice IMO

 

My rough draft of how I will be making the bank

 

I was browsing eBay for those hybrid battery sticks last week as well. I can run at 15v with my alt so I was thinking about doing it. Very interested to see how those work for you. :thumbsup:

 

After doing the testing I've done with them I wont do anything else I've hammered them as single 7.5v sticks and doubled up as 15v sticks on my battery load tester time after time and back to back with 50amp and 100amp loads to the point tou could of roasted marshmallows on it from the loads and they bounced back every-time with little loss of voltage

 

so,
...
any progress?

 

How are you charging and reviving the batteries? I founded some on fleabay and I wanna play with a set.

 

I'm using a Imax B6AC NiMh rc charger basically,that's what I've read is the best thing to use since you adjust the discharge and charge rates and there cheap too. I put them on a discharge/charge cycle I've only had 3 I had to cycle more than once to bring them back


I have just one left to revive so I started putting on the new heat shrink

I ordered some custom cap straps like below to link them together for 15.5v just have to wait till they come in this week then I can get my layout measurements for the front plates

The guy makes quality items everything from lugs, to distribution blocks fuse blocks encased with laser etched acrylic and full custom anything you want he's cool to work with check his stuff out. I have some custom Distro blocks coming in with the straps that i will post here when they arrive.

This is what i'm looking to have made once I get the straps in, I will have some Acrylic covering the face also

I's moving along slowly and will be starting on cutting into it once it all arrives, but like everyone else I'm the holidays are crimping the funds
