Hdc318

First off With only 1100rms try a 11cf enclosure tuned to 38HZ, the lack of power is just gonna mean that you need to make it up with airspace. Plus the box will be alot more more efficient if it has more cf. meaning less imp rise and getting louder off of less power due to reaching its mech limits fastaaa. If you put that thing in a 5.5 cf box I doubt it would move more than half an inch off of 1k watts..

not to bad really heres what it looks like

yeah that was just off the top of my head i mean it really depends on your car too, but for example I have an hdc3 15 a series only on a aq 1200 @ .5ohms in a 5.7 cf box and it excursions about 3 inches at full tilt with minimal clipping, but due to the power being low and in a very efficient box the clipping doesnt really give it to much cooling trouble it still manages to remain cool. And on a 50hz tone it was seeing box rise of .25ohms making it a total of .75 which isnt to bad. But it was only pushing 1200 watts at .75ohms on a 50 hz tone.. :/

So the Fs is pretty different on the copper coils? Im looking at fitting 2 in my blazer. I will be limited to only giving them about 5 cubes each with around 160 sq in of port. I was thinkin of getting a 3500D from AQ to push the pair for the time being. In the future it may end up with a 2200D on each one or a 3500D on each. What is a good tuning for 5 cubes? I have looked at 28, 30 and 38, so far i was leaning towards 30Hz.

32-34hz you'll be fine with coppers on the 3500. Should sound great if you can really do 160 sq in of port (displaces 3.5 cubes at 34hz //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif).

tragic that he has no numbers and only uses winisd...which people have proven to be wrong.

i would say 5.5 net would be just fine tuned to 38 hz...

For someone ripping on people for 'not helping out' you sure give some crappy advice...if he had more power I may suggest that airspace..

Granted an enclosure with these specs (with a port area of decent size) would get 'loud'/make noise...it definitely wouldnt get the most out of the sub using little power...I would suggest going larger on the airspace because of the lower power you're giving it.

I'd run over 3kW to it. Those spiders on the 18's are really stiff.

okay now will having the box built where my back seat is hurt the sound? have a very small car!

 

[tragic_magic]

i guess i know nothing about hdc3 18's in huge boxes on low power (2400 rms)

thats 22cf @ 41hz

Looks like it could cause a hurricane in that van
