Posted January 9, 201411 yr Got the call from someone local to build a box for his setup. He has 2 SSA Evil 18's on 2 NS-1's at 0.5 ohms a piece, with 4 XS D3100's and a Mechman 270. His current box was initially built for 4 18's (something like 18 cubes net) and stuck WAY above the window line. He wanted a box for just the 2 that he has, a lot smaller box, and something with a little "flair". Well, here it is...Specs:13.2 cubes net12" Octaport32.3 hzDouble layered all around (except sides)Window style bracingBolt terminalsBedlined outside with a fire-engine red portBe sure to watch the video at the end!
January 9, 201411 yr Author In the video the amps were clipping and with the electrical still has some work to be done, but the subs were only moving 1/2-3/4", and theres still THAT much flex. Will be properly setting the gains on Saturday, along with putting it on the meter. Was definitely not built for peak spl, so I'll be getting numbers from 25-50 hz.
January 9, 201411 yr Box looks really good! But you should tell him his electrical is not even close to being optimal. He needs to quadruple his battery bank and add another alt.
January 9, 201411 yr Author Id say subs were getting no more than 6-7k. With the amps not being set right (I think he said gains all the way up), I'm nor surprised they were getting warm without seeing much power. He's adding another Mechman 270 and 2 more D3100's soon. And thank you. This box sound amazing.

And thank you. This box sound amazing. Tell him to back the gains down a little. we're having a little meet and greet on Saturday with a bunch of audio guys around Oklahoma, and we'll be setting his gains properly with an o-scope. Also, he has each sub wired to it's own amp, so to simplify the system, we'll be strapping his amps so he just has one gain knob to worry about, and the signals will be perfectly even.
January 9, 201411 yr Author God I bet that is loud... Guessing that the subs were only seeing half of the power he has available, he's in the low-mid 50's. It's a low end monster. He honestly doesn't care about numbers, the only thing he likes is Decaf. And by god, this thing can play it. haha.
January 9, 201411 yr Don't use the o-scope to set the gains. Use you're ears and turn the gain up till you hear stress/distortion and then back down the gain a little bit.

Tell him to shoot us an email when he is ready to work on the batteries and alt's.

Maybe we need to send some SSA guys near you, your way for enclosures if they want something custom like this.

I'm located around central Oklahoma.

January 10, 201411 yr Author Thank you. Tomorrow will be test and tune day. Trying to reposition the box to squeeze out numbers is going to be a PAIN. The box/sub combo weighs about 400-450 lbs. And that combo on carpet does not slide very well. Haha
January 10, 201411 yr Author Also, i forgot to mentio he's layered the ENTIRE vehicle with SecondSkin Damplifier Pro... Thats why only solid structures like the doors and whole back hatch are flexing.
January 10, 201411 yr Author Customer shot this video last night. About to tear his hat UP. http://youtu.be/RhrGGniyEKg
January 11, 201411 yr Author Had a meet up today. What was going to be 3-4 people turned into 15vehicles meeting up and showing off their systems. Got the amps strappedand tuned properly. Managed to pull off a 154 in the kick at 38 hz and a150 at 30 hz. A few things to point out:1.) ZERO sound deadener on the roof. Theres deadener everywhere else, but the roof.2.) Yes, the truck peaks at 38. Does a 150 at 30 hz also. It's a low end monster.3.) Voltage is dropping down to 10.3-10.5 (SMD VM-1 is NOT ACCURATE from the cigarette lighter)Didn'tmanage to get any videos this time, but I will next time I see him.He's calling Mechman soon to order a second alt (probably a 380 orbigger to go along with his 270), and a couple of more XS batteries.Customer is ecstatic about everything, and absolutely loves how itsounds. The entire truck just shakes on the low notes.
January 12, 201411 yr Author Video the customer shot of a 153.8 run. It's a lot louder to the ear. Could be because it peaks SO LOW. http://youtu.be/ua5w9S3jLMM
