Empty venue indeed... I feel you. Cabin work is one of the most overlooked things in car audio. What is on or going on the floor? Once you deaden that you'll find all sorts of places needing attention. Keep on building and know the peanut gallery is taking it all in.

About 10yr ago I made due with what was available to me and built a dual 12 setup that went from 145db to +149db on the same power. Deadening is paramount to real results,

I blew the hinges off the rear glass at a show once, I'm sure the 200lb of deadening had nothing to do with what happened.

My build is fully deadened. I have 2 layers of deadener, neoprene, and 2 lb. mass loaded vinyl under the carpet. I have an 8" midbass that is going in the floor up front inverted that vents into the frame rails. The baffle I am mounting to the floor has non hardening modeling clay and bb's encapsulated by reinforced fiberglass. There is a few pictures of them being built a couple pages back.

So before I show the update of the doors; which I just had a post for, and my browser crashed. ..Here is a pic of the next project in the list. I am going to add an air motion transformer as a wideband midrange.

Ok I had a longer post written out for this but my browser crashed so I'll keep it short and sweet.
I started by making a template out of tape.


I added some washers to the hardware to give a little more clamping force.

I had to do a little panel modification for the baffle clearance and to make sure the door card mounts sit flush against the metal of the door.



Here is the beginning of the baffle. It is 1" thick. After the mods that I do to it and attach the baffle together with everything it will be incredibly strong.



Here is a shot of me having modified the base the baffle will sit on. I didnt want to build out the panels too far so I cut some holes in order for the magnets of the midbass to clear.

I made some standoffs to hold the baffle out at a distance. I cut a notch in it so it would clear the washer/screw combo.



I thought I had taken a picture of the first layer of standoffs but I guess I didn't. The shape is a little unorthodx but I didn't need it to go completely across the length of the base. Below is a picture of the second layer installed. I believe I will add another, smaller 1" standoff in the left side, which would be closer to the outside edge of the dooor.



Here is a picture of the mdf rings attached to the baffle. This ended up giving me the space that I needed for the mount depth of the midbass. As youcan tell there is a bit more work to do and I will need to mirror this on the passenger side as well. More later.

It's been a hot minute since I've made any build posts. Here are a few pics of the new door panels. I have 2 10" midbass from SB Acoustics in the doors now. It really improved the midbass response. The top section of the door that is cut out is for a 6" driver going on axis at the top of the door

This is what the car looks like as of 30 minutes ago.

Dual 10" midbass drivers improved midbass response. Who woulda guessed.

Here is a few photos of what I am working on this week. 6.5" midrange on axis. I will add a few more photos later.

Attempting to blow your face off with an 8" PA speaker????

I would use an 8" if I could but as it stands I'm right at the limit. I can actually do a 7"on this baffle so I may do a little experimention later. It will be bandpassed and T/A. You wouldn't want to try this setup without it.

What are doing for processing? What 7" are planning to use.

Dayton Audio has a full range that I would like to to try out. I think I will use one of my jbl dsp amps for power and processing.
