I agree. im holding off on getting another sundown amp for some comps. I might just get the sundown soon instead of waiting for some news on this

i just stuck the port in for that picture. Trust me when i measured it up it was 3.25 inches from the back, and i added in a piece to help the air around the corner. Also you should only subtract .75 inches from the total depth because the front thickness on the box is part of the port, and the port is 17.75 inches...i just round to 18. It doesnt change the tunning that much.

I have 2 12" 187's from incriminator audio in a custom built 4.4 ft^3 box tuned to 31hz powered by a sundown saz-1000D and on some songs the bass just is not there on the low end. The song in question is hypnotize by jeezy. I never really noticed the problem until my friend played the song on his infinity's in a prefabed box and it sounded so much better. Ok the problem is when the song begins there is not a lot of bass. I can feel it a bit but it is not too audible, and when the higher frequency note hits it is so loud. But that is really the only note i can hear well. My subs barely move during the parts in question. the part i have a problem with is from :27 to :40, and it continues throughout the whole song. I thought it could be my subsonic was too high, but i turned it all the way down to 10hz so that is not the problem. I have the bass set the 0 on headunit and the gain properly set, but the sound just isnt there. This also happens on late night tip, but i just though my subs weren't powerful enough for those lows. I know its long, but i appreciate the help edit: kinda looks like these subs in this video http://www.youtube.com/watch?v=2iYlJElrtgs&feature=related

wow i was actually thinking of asking if i could do that. what do you recommend to plug the port? This will probably have to wait till spring though...its almost freezing in ohio...global warming my ass

The box is 34x15x21 (lxhxd) and the port is 3.25x13.5x18 just plugged it into re box creator and it says 4.34 ft^3 tuned to 30.57. So it will be a littler higher after the .2 from woofer displacement

Well when i first played them i was listening to lost by gorilla zoe and in audacity it says that song peaks at 32 and 34hz, and that song is so loud on the subs. Listening to some test tones, they peak around 40 hz so that would suggest the box is tuned around the low 30's. As far as cancellation, would that cause the subs to not move? Im going to try to borrow a friends camera to record it, but the subs hardly move, thats why i dont think its all cancellation. Also if it was 100% cancellation the peak and the trough would have to hit my ears at the same exact time, and a 30 hz wave is 24 feet long so i would have to be 12 feet away from my subs and i am about 5-6 feet away, also wouldn't i hear the subs as being louder a different distances then, depending on where i am in relation to my car?

i could run sweeps using my computer through the aux port with winISD, or i just downloaded some test tones, i think shizzon put them up. I dont have a tl though so i would just have to do it by sight i guess. Any other ideas?

i have pics of everything in that thread. I know there is a little cancellation because of how my port is aimed, but it should not be that extreme ( just wanted to take some of the load off of the trunk lid) I have the subs at least 4 inches away from the port. i heard that you want them to be at least a ports with from the port. They are in a 08 cobalt with stock electrical. I only get a little dimming at night when im at a light. As long as my rpm's are over 1000 there is no dimming. I tried turning my subsonic down and it still didnt work. its confusing the hell out of me

i tried that. i had the gain almost all the way up and i started to get a little worried. i didnt want to blow them, but they took all the power with no problem, but the problem still precised. It is confusing the hell out of me. Hopefully upgrading from stock headunit this month will make a difference. It could just be the stock one crapping out

port is 13.5 inches high 3.25 inches wide and 18 inches deep

in my post i mention i have everything set. LPF is set to 80hz subsonic is set around 25HZ. Checked the song to see where it peaks in audacity and it peaks around 34hz and 39hz

yeah they are really nice, and quite heavy for a 300 watt woofer. You can just tell by the construction that they can take more power. Im really glad i stumbled onto this company. Great products for a great price keep it up guys

Thats the same setup i got going right now. They really love the power from that amp :] awesome,any pics ,vids, ? i failed!!! i followed your post, all three pages, just didn't look to see who commented. lol..... how is the setup doing, breaking in and getting louder? It has gotten a lot louder!!!! I just cant wait to get some sound deadener because i cant really hear if the subs are distorting or not because of all the rattles so i keep it toned down just a bit. I dont have a vid camera. I tried one with my phone but the sound is all screwed up. Ill have to try with my parents digital camera one day

Thats the same setup i got going right now. They really love the power from that amp :]

You know, you never did answer what part of Ohio you are from, lol. yeah i did i said im up by cleveland

yeah just set the gains right. I have 2 12 inch 187 off a sundown saz-1000d and it runs just fine. They really love the power

Cant expect to build the best box ever on the first try

you just lose a little port volume, so it will be like tuned just a little higer... like .5hz or something so no big deal. At least i think so

mine was like that too. i lost a little width in the port, but i put some wood in the port so it would be the right width when i screwed the side to the top

looks nice. got that build pretty quick too...mine took like 4 weeks

sure thing pal ... haha that would be awesome... we can always dream cant we

damn dude. Cant wait till those break in!!!! Going to see some impressive numbers with that. So... after you finish that car want to work on mine

yeah its a physics thing. Conservation of energy. The sound energy is being converted into mechanical energy aka vibrating panels. If you can prevent those panels from vibrating all of the energy stays in the form of sound waves, therefore you get more spl

man you would really hate my car right now ;] I really need to get some sound deadener

nice. finally get a bigger amp for the sub?
