Why are you suppose to put the subsonic ~~3hz below? So if I have my box tuned to 32 and I set the filter to 29, wouldn't the amp not play below 29?The guys above me explained it. It's actually suppose to be set some specific way with equations or something but a few hz below tuning is a pretty good way to do it.

What's your tuning? Put the subsonic like 3hz below tuning. Set your low pass to around 80. Then turn your headunit volume up 75%. Then go to amp and turn the gain up until you hear distortion. Back off just a little bit once you hear it.

I hate when that happens!!!! The crescendos are great amps. I had 2 bc2ks and I loved them. If you want to get the c1100.4 just to match the 3500 then I guess that's fine but you don't need it. You don't even need that many speakers. One set of components up front would be plenty. Ssa does show recommend box size on their website. http://products.soundsolutionsaudio.com/index.php/product-information/xcon.html Go all the way down and it says enclosure recommendations. I use Torres box calc. Type in Torres box calculator in google and it'll be the first one on S M D forum.

Yea I am. I'm on vacation till Thursday though.

Uhh well I guess I really didn't need that much and the weight was an issue. I wanted to get some money back so I could buy my AR15. I have another 12 coming so ill have 2 xcons on the 2500

This guy hasn't been online since February. Just lettin you guys know!

No way to tell you man. Pretty much only way is to actually test both of them out. Might do a lot better on the lows, but I don't know how the mojos do on the lows. The z v.4 and X series were designed to be brutal on the lows.

Chris from DB-r is an awesome guy. Made my buy from him very easy. Answered all my questions. I bought a refurbished saz2500 and it works great! And yea Sundown's name speaks for itself.

Haha Jon http://www.db-r.com/sell/store2/index.php?main_page=product_info&cPath=65_67_69_125&products_id=350

Xcons are badass subs. My 12 is loud as ballssss

Check your last thread. I posted an amp suggestion in there.

I would try and get better quality. It doesn't have to be 1200 rms since a few hundred watts wont make a difference. I would look at used. Check http://www.db-r.com/sell/store2/index.php?main_page=product_info&cPath=65_67_69_125&products_id=350 out. I bought a sundown saz2500 from there which was refurbished and it works like a brand new one. Comes with a 1 year db-r warranty too. $289 plus shipping. Better than hifonics!

I can check for you. What tuning would you want? And how much power?

You sure you saw my designs? Lol thanks man! If you need any help with it let me know. I think the 2 d3400s and the stock battery will be good with a HO alt. check out singer! I would suggest some xcons man! I have 1 12 right now on ~1000 rms and it slams so hard. Sounds absolutely amazing doing it too. If you want more output but still sounding good than zcons. But xcons get super loud too. I can't wait to get 2 12s on 2500 rms. What are you powering with the c1100.4? What kind of music do you listen too?

I'm on vacation till next week so I can then!

I'm very sorry man. He sounded like a great guy.

What I did was jus measure the distance from the box to the side and then up. Cut a wood to that measurements and if it curves on the top like mine then take your piece you cut and hold it up next to the box and use a pencil to trace the curve. I don't know if that make sense, but if it doesn't I can take a buch of pics showing you what I mean!

Your design. Remember. . 2.8cubes @33. Due to my amateur woodworking skills I think the tuning ended up being 31.5 ish tho. Yes now I do!! It was a while ago and I've designed a few more boxes since then. Turned out good man!

I don't recommend running 18s if you want the cooler and that's the biggest you can go. I would run 15s. I explained before why because of the port area and already small box volume. I'm pretty sure the 15s would get louder and sound a million times better.I design boxes too. If you want I can help you make one for some 15s. We can make it as wide and tall as it can go and then make the depth the shortest we can go while still keeping it optimal. This way you should still be able to fit coolers and more stuff in there. As for power, I am 100% fine with 2500 rms and 2 12s. Adding that 2500 will get you louder but it's going to cost a lot to get that little extra bit louder. I don't see it worth it IMO since its for daily. Even for two 2500s you don't need dual Alts. 1 high output alt would be plenty. How many/what kind of batteries do you have? What's your budget for subs only?

What 18s are you going to run? When designing a box you design it for that specific sub. Can't really design a box if you don't have a sub figured out. Also your port area is small for 2 18s. That's around what 2 15s use. Port area is very important. Do you really need that cooler? The way I see it from what you have is either 2 15s or ditch the cooler. The box size is just a tad under what most 18s need and adding more port area will decrease the box volume and increase tuning (while leaving same port length). Edit: Just noticed you have the port and subs facing different ways. That's not a good idea. Can't remember exactly why but I think it's a cancellation issue or something. Somebody else can explain why.

Nicee! Are you going to carpet/paint the box? Also since its facing forward, are you gonna seal it off?

Meant size of wire for both sub and speakers is good lol Alton answers the rest of the questions and goes into a lot of detail. Whatever he says is right haha he knows his shit! Last thing is if I were you. I would run a 2 channel to a set of components (4 channel if you go active and Alton explains active) and a monoblock class d amp to the sub or subs. This would also be less money.

People on YouTube are hitting high 40s to low 50s with 2 12s. Don't know how they're metering but I know it's at low hz.

Box and install looks very nice!! What's the specs on the box? I have 1 12 Xcon right now and it impresses me every time I hear it! I can't wait to get my second one in soon.

Your port area is very small. I would definitely add more port area. Box size seems pretty small. Idk the box recommendations for the ssd though. When you tune low like 31hz, the high bass like 55hz and up will not be as loud as if the box were tuned to 40hz. If you want I can design you a box. I can make a 3d sketch up and a cut sheet for you so you know it will be built right.
