new buid 2 sd 8 d4 with ct 1400.1 amp. any ideas?

Sounds good but want the bass to sound deeper

You need a box with the port tuned lower

What are the settings on your amplifier tuned to?

iam not sure what the amps tuned at right I've only havd the ct amp for a day was running a auto Tec mean machine 500watt but it could push both subs pop fuses after running it for 10 min or so

Port calculated that the entire box is 5.505 ft3 if I put two 2in by 3in long ports on each tuned to39 hrz. That should give me good lower bass

if you were popping fuses and do not know how you have your new amp setup, something is wrong.

Can you post a picture of how you have your settings on the amp? that could be why your bass is not what you want it to be.

Also a picture of your amp ground, thanks.

It will be a little bit befor I can send any pics of the box set up and ground wire, and the ct amp is barely even turned up. How I set the gain was turned the raido up to were I wanted it then adjusted it with the bass, lpf,subsonic,and phase tuned all the way down the bass is 1/4 turn lpf is a little over 1/4 turn and the subsonic the same

and subs are wired in parallel at 1ohm

How did you figure your volume of your box? Did I read it correctly where you think you have 5.5 cubic feet of volume? If your box is 50" wide by 10" tall, by 10" deep(i have NO clue what you're referring to with whee the 3" on that back side comment", you're actually at 2.02 cubic feet before sub displacement and port displacement. I don't know what you're using for your math or maybe you posted your outer dimensions incorrectly.

My suggestion is to give us max useable dimensions and let us design you a box that is correct. The box you have, my feeling anyway, needs to go in the scrap pile. There nothing wrong with that, we've all made mistakes.

If you're using 3/4" wood, and assuming you're at 10" depth(measured externally) I come up with 2.63 cubic feet, before sub and port displacement. Pictures well help a bunch.
