wondering if anyone could help.
after a failed first at building a box on my own im looking for some help i have a sundown e8v2 that im trying to have a down fired ported box for. it will be installed in a 05 ecsb i came up with these for dimensions.
20in wide, 12in deep, 8in tall

if i go over the drivetrain hump i can have a little more room.
this was the first box that i built and it sounded horrible,

i was told to cut the external port off and try it but that still didnt help and sounds like ***. any chances you could design something for me?

 

I might be able to help you out bro! let me do some research. Does the the rear becnch taper down as it moves to the rear. Could you get height measurement from the floor to the bottom of the bench in the front and back of the bench. From the inside edge of the seat bracket to the inside edge of the the hump. Width and height of the hump. Plus any specs on the sub that you have.

Cool, give me a few days and i'll see if can get something put together for you.

 

sounds good to me, thanks

 

Just wanted to get back to you, didn't forget about you. have it worked out and will get a sketh with dims. put together tommorw and post it up.

 

This is what I came up with. If you have questions, feel free to ask. Keep in mind that if you are going to down fire it, you going to need to add some spacers to the bottom to give the sub room to not hit the floor.

 

thanks again......working on the other design tonight. try to get you yours next weekend
