Sundown Audio

My box design for 8 x-12's, 4 CA 3500's


Recommended Posts

You have an expedition. I'm sure you have more than enough room. Don't worry about tuning to 28 hz. As long as you arent overpwoering some ungodly amount you can still play under tuning. Id shoot for 33 or so to be honest. But you need to build bigger stronger and better with more port area. That thing would shred itself in minutes single baffled all the way around.

I know, my measurements were with the side panels still intact, I still gotta rip all that good stuff out and get some new measurements and see what im working exactly. The amps I wanna put two racks in, 1 on each side of the car in the windows slanted. I just gotta dive in and get a box built So I can build the rest of the car lol.

^^^Agree with the others. 300+ inches of port to start and 1.5" on all sides. Tuning in mid to low 30s. Those subs will do their job in a box without high 20s tuning. High 20s is silly to me if you plan on playing ANYTHING other than Decaf or chopped and screwed music.

I really only been playing decaf and low hitting songs. Don't big into high note songs. I will change it if i don't like how it hits.

this is what i came up with. Port is still small for me, but not knowing how much height you are willing to give up, this is about as good as it is going to get. Doubled all around, triple baffle, didnt do bracing because it is just a visual representation.

Thanks for the help with specs. I will take them into consideration :P. I kinda wanna keep the top of the box level with the top of my back seats head rest. but I may have to sacrifice that want lol.

if you want a box that wont flex and is done right, you will.

seee you are thinking in whats going to look cool. not whats going to work. Your wire runs with amps in each window are going to be retarded long. not to mention you will have to fabricate a mount that can take abuse to hold them. more than likely it would need welded in as well or lse its not going to last. If you really want some amps to come humpty dumptying then by all means you can get away with cutting corners.

Not that I'm half as good in audio as many of your replies. But when I think of something I shoot for the most functional design and try to make it cool while still keeping things 100% functional.

Ex, if the amps gotta be logo upside down to be functional > looks then I do that. If I gotta have these wires showing but I have more cooling for my amps, I do that. Ect ect.

Try looking at it in a "ideal functional" mind set and try to make it look pretty from there. 4 15's or 6 12's might be better functional because you can double layer the whole box and maybe even a triple layer on the top to add more strength. Putting the amps together instead of on opposite sides of the vehicle, with the power inputs facing closest to your battery bank for short clean wire runs that don't cross over RCA's and speaker wires would also be another thing.

Just food for thought.

I just thought it would be a good spot for the amps since I'm keeping the back seats. I don't wanna have room under the seats due to that is where the 1100.4's are going. And the bats are going under the front of the box where the 3rd row seating folds down into. Only other option would be to mount them on the front of box behind the seats. Would be closer to the bats :0

RE did the box after talking with 1clio6. Took his advise. Came up with this. The supports are half inch threaded rod. triple baffle on top, double all around. And I even put the amps on front of the box. Lemme know what you guys think of that. P.s. Yes I'm gonna round the edges of the port and supports in the port. Also the cut outs are the actually size of the gasket of the speaker. Not sure why i did that lol. Cut out is inch n half less in diameter sp 3/4 inches off each side. so its not so scarey looking at how close the holes are lol.
