excuse my ignorance but, how are the bus bars not shorting out on the metal battery tray?

There's 1/4" acrylic between the buss bars and the steel.

I've been wondering the same damn thing lol.

[BP1Fanatic]

Lol!

[MADVIBES]

well, that answers my question. creative!

Lol, yeah, there's a layer of black under the caps and under each side of the buss bars

So did a few things to hopefully help minimize the enclosure flex I've been experiencing.  The whole wall moves which ends up throwing quite a bit of vibration into the amp rack.

 

For those wondering why I had holes drilled in the angle iron bracing on the roof:

 

Also sealed up the holes where the grounds run into the bed

Added another piece of birch to sandwich the cab between wood so it hopefully holds a bit better

Made the mistake of attempting to sink the door plate in so the electromagnet would pull the door closed tighter and stripped out the hole for the lag bolt. I decided to make a plate and due to using too thin of steel, it ended up nerfing the maglock.  

Basically killed the holding force so now I have to figure out a new way to attach the original plate to the door.   My goal last night was to get a baseline number before making the tuning changes I've been planning on which potentially could result in very significant gains if my theory is correct.

Well, I got the lock to half way engage and sent it...door popped open on roll up and I was trying to hold it closed by the door handle, which wasn't very successful lol. But still managed to get within 3 tenths of my previous best, even with the door half open lmao

I was so frustrated by this point I decided to call it a night.

Going to take another crack at it tonight

Why the watts say 0?

Clamp wasn't working for some reason.

 

 

Little update:

Since I had the door panel off, figured I'd put in a better seal.

 

Maglock officially back and better than ever! Much more secure than before. Ended up drilling the stripped hole out and using a lag shield.

 

Door isn't quite as tight as I'd like but it's much better than before.

 

NowI just need to cut some wood to change the ports up. Got a show tomorrow morning and have toleave at 6am, but at least I got a good night of sleep last night lol.

Thanks man.

 

Did a bit more work and got this:

Rising to 1.8ohm from .5 nominal!  High notes are a lot better after shrinking the port. Seems like 1.8ohm is the lowest rise in the pass band so I think I'm going to go for broke and strap at .5 and see what happens muhahaha
