Have found more pics. The battery box was finished for the most part. But after some amp issues and launguage barrier issues, The D1000 have been sent to Murilo and now am using these Deka group 34 12 volts I get for free from work. They seem to be doin the job, although top posts are a bit of an issue to make bus bar connect, I have now some 3/4 X 1.5" flat that will replace the 3/8 X 1 flat that is in the pics. Just need time to drill and tap about 24 holes in each peice and get 5 more of them batts...

Here is what is in there now, the volt meters show the voltage drop under load with charge. drops from 13.5 to 12.7 / 12.5. but with car off it drops alot more than that. So these batts are not that strong, but the price is right
and seems to be working atm.

Had a casualty on the build day, one piece of the tubing fell out of place and stabbed the surround, but he is still working ok. The lumber store was all out of birch ply and not recieving for awhile, and the other that did have some was 5X7 sheet and was like 70$ so pfft. I had some mdf laying around yet and so must use it for one layer as much as dont want to use any in the shell of the enclosure but I must get the B pillar sealed, The roof is moving 2" peak to peak and I aint going to be fixing that kind of damage... So It aint quite done yet but have 1.5 sheets of birch left to install on the sides walls and then seal the B pillar. This will be as far as the build will go until the new year I am thinking. Every weekend from now till the new year is booked. I may be a to steel a few hours here and there but nothing that will allow for the dash build and such things. Now I must try to find a another instrument cluster, On way home last night it burnt a gnd trace in the printed part and gauges or lights not working. maybe solder ??? never really tried it but that stuff is pretty light ..

I found this power test hiding in a folder and was wondering where it was.
This was done when first built the current design. I stopped measure amp current draw as it was taking too much time and not to interested in amp eff.
More wanted to see how my rise was and what kinda power It was making at different freqs at a set test volume of 170 volts from amp with no connection. ( this was measured as per alsniffer instructions on caco) the volume seems too low as does power ratings but I know when turned up a few notches the volume increases huge on his amps.
Maybe he can chime in on it

Hey Corey,
I can barely see the power test table, seems to be the same as the one you sent me.
If it is, you can see you limited the amp at around 115V, and as it has a 250V+ power supply you are good to push it up until you see clipping with load. Provided you are feeding it properly you will see around 170Vac before clipping. If you voltage is dropping substantially you will see less than that.

BTW, good job on bringing the build to the B pillar.
You should try something that might be new, bring the subs to the front while keeping a path all the way to the back, building a BIG TL, so you use both sides of the cones more efficiently. Try a loading wall so you have a cavity for the meter.
I was going to try that before my van was stolen.
