Karma got you...for stealing my top

Damnit Adrian! My top!!

Good luck sir! I need one too

i dont think i can ues 5" tall port but i can do 4"x30"x21.5deep should be around 35hz or so and 8 cubes net will this be a good box That sounds good, I just checked the numbers, go for it. thanks for all your help bro No problem Bobby.

Much more than x-max is needed to compare anything.

Why do you personally think x-max is so important in a sealed enclosure application?

You'll want to make the port 5" x 24" x 30" long for your 120 sq inches and a tuning of 34 HZ.

You should only have 2 sets of components and that would be plenty of output for you, when you start adding speakers you run into cancellation. You only need one set of properly positioned components in each side of the vehicle.

so i can go with 8cubes after diss, and 120sqin of port do i keep it 21.5" deep or shorten it? thanks for the fast reply What are all the dimensions for your enclosure?

Yeah buddy I doubt they would. OH maybe because sealed enclosures aren't made to be loud.

Increase port area, about 120 sq. inches is the largest I would go though.

Don't do it. Why do you want more tweeter in the first place?

So you have an 8 gauge ground when you need a 1/0 gauge ground?

I've never seen them before.

Dampening simply reduces panels from vibrating.

Because it's one small parameter of the subwoofer, it doesn't really matter when picking a woofer. Look at Digital Designs, the loudest single subwoofer in the world doesn't have a gigillion x-max, it's very small actually. X-max does not equal loud.

Whichever one you put in the better enclosure will be louder.

I tried with the back cover off and couldnt get any output but that was with 8 gauge ground. umm.. i think my ground was fishy so i re did that and my 0gauge wire wasnt long enough so i only had 8gauge. tomorrow i will pick up more 0gauge and then try the 3000d again. idk if pics of my amps guts would help but if so let me know. thanks You had an 8 gauge ground on a 3000 watt amp that requires a 1/0 gauge ground?

That amp is rated for 1200 watts at 1 ohm. You have a dual 2 ohm sub, that would be wired in parallel to create a 1 ohm load on the amp. For the calculations you use the impedance load that sub will put on the amp which is 1 ohm. That comes out to 34.6 volts. Sundown is probably recommending a tad higher at 36 volts due to the fact that the amp could put out a little over 1200 watts with the proper electrical. Also, follow the recommendations that Duran said earlier. Ohhh, gotchya. Forgot that step. So when I'm at 0 bass, and I can't get the 36 volts, can I turn the bass boost up a tad? Or how would I go about doing that. If everything is set flat then you should be able to get the voltage you are looking for. Even with 2 volt preouts. What is the HU volume at? If you do have to turn up the boost, don't turn it any higher than where it was when you set everything up. When listening to it that is. The headunit volume goes a little over half way. If It gets any louder the factory front speakers will get to loud and start to distort. If the front speakers are on the HU adjust it so they don't distort, if they are amped get them with a DMM like you are with your sub, just a 1KHZ tone instead.

*Cheers*

Is that why there are foam pads on the tops of them?

Bass should be at zero, don't use it. Turn your "loud" function off as well. Set it with a DMM and preferably an oscilloscope. If you wanted output why did you buy a Q?

Of he grounds correctly he won't have a ground loop. Both of my batteries are on their own ground on different parts of the frame. And you don't need to run a ground from front to back. When you do your front battery ground in 2/0, and ground your back batteries to the frame in 2/0 your essentially using your frame rail as your wire run. You can connect all your amps to one battery if you wish, it doesn't matter, they are all connected anyways and you are really just making one BIG battery.
