You didnt make any space for mounting a grill.
You should have placed the baffle some 5cm towards the back of the box.

It seems cost is the motive, after reading the thread. So he might go with...

Worst case scenario he can attach shims as a frame for a full size grille to sit in.

yes I bought a pair of grills from parts express, my friend is cutting it for me right now. The grill wasnt long enough so I had to take some from the width and add to the height.

Nice job. How much does it weigh with drivers?

it weighs about 140-150 lbs, not light, but good dimensions, not that high but deep.

When you have them all done could you post a picture?
Also a link to the plans?

question about power amp, thinking about building more of these subs and powering them with a crest ca18 or ca12 .. cause I want to run them in parallel to get more out of them. Looking at the impedance response curve I can get down to 2 ohms. But how would you provide power to the amp, I see these amps require up to 60 amp service, can you build or buy something that can store the power? like a capacitor?

No... you just use a power source that has a large enough supply.

The amplifiers will not draw 60A.  Check the spec sheer for ratings for 1/3 and 1/8 power.  If you've got enough subs/amps the most you should be drawing is about 1/8 (that's the average power the amplifier draws when you're just barely touching the clip lights).

I would think you'd be more than fine running each one on a 15 or 20A circuit.
