Not sure how the box is gonna act. When I first posted the box design other people asked me if I expected it to act like 6th order. With the measurements I came up with the front chamber is tuned to about 210hz and the rear is tuned at 34hz. The more it gets questioned, the more I wanna build it just to see what it will do.

Awesome looking GMT400 (Chevy Truck) !!!

Are you going to be using a bed cover ???

Also, are you going to be using 2 batteries under the hood ???

If I can find the older style snuptop tonneau cover I will cover it. But either way the box will get covered in bed liner. I will probably put the Batteries in the bed next to the box in front of the wheel hump.

Great project to start with!!

Cant tell from the pictures or not, but whats on the ass of that thing? Do you have a shiny bumper or a smooth rollpan?

Love the shaved handles, and your box design!

I wonder how that thing will sound? Should be interesting!

I still have the old stock bumper. A roll pan should get ordered around tax return time. I am also gonna reloacate the tail gate handle to the inside. The door handles took about 12hrs to do. When I was done I realized it should have only taken about 4hrs.

Gonna try to get the clutch pedal assembly swap done this weekend. So hopefully I will have some updates soon.

And I am planning on putting the battery's in the bed next to the box.

Definitely going to follow and stick around. Been looking for a good GMT400 build to follow that isnt 20 or so pages in already.

No system planned just yet.

Look at "hate" spelled backwards. It spells "e-tah." For example, if you hate me you can e-tah dick.
