thebiggmann12

have u tried using the re box calculator to get ur specs?

off topic but where is plainfield?

lol shizzon. if ur trying to build it in the backseat u can go 45" wide and all the way to the back of the front seats is about 30" or so. and then as tall as u want. u could def do 2 15"s hell u could do 2 18"s. thats what i was going to do, just make sure u do ur electrical if ur gonna go high wattage.

i would try building another box in the hatch area, before u go buying more subs..but it really depends on how much output ur looking for...if u looking for mid 140's im guessing the 12 isnt gonna do it. but if ur just looking for something that sounds good and still has a good deal of thump, then stick with the 12 and build another box.

also, u might b able to do a 2 15 setup in the hatch area, ur dimensions are 35 wide 20 deep and i did it 22 high, which was a little above the seat but not much.

make sure u sound deaden that hatch..it rattles like hell with the sub and port facing it.

yea i like to change it up alot. the nightshade is alot louder but also geared towards spl more. def go sub n port up if u want to keep ur backseat

try sub up port up. it works the best and sounds the best.

might as well put an 18 in it. i had an 18" Q in my focus and it was rediculous.

i think it looks pretty good. nice and clean

alright will do. thanx.

yea i figured it was something like that but i have heard from a few people that they were low end monsters...o well not a big deal for me, but the nightshade does sound better than the q, definately hits a bigger margin of frequencies. but if the port area seams about right, then i will probably just build another box maybe tuned a bit lower, but overall about the same size and then do 45's in the corners and fiberglass the inside.

ok so i built a box for my new nightshade 18. it is just under 5 cubic feet before sub displacement but after port displacement. it is tuned to 31 hz b4 the sub. it sounds great. my question is if the port area is too small. the re calculator that i used said that the square port area was 55.5. idk if this means inches or what but im guessing inches. the sub performs great at higher frequencies but the lows are kinda lacking compared to the 18" fi q that i had before. any info would be great. also if somebody would be willing to design me an optimal box that would be great too. my dimensions are 36" wide 22" tall and 20" deep. sub and port would have to be facing up. i like the lower frequencies alot. i like my highs too but low lows (between 27ish and 38ish hz) are what i love. any help would be greatly appreciated. thanx.

lol i got winisd, but im not 100 percent sure how to use it...it was pretty complicated for me. i want to figure it out tho.

lol i got a terrible grade in geometry...i think im just going to stick with re calculator. it worked out great on my q

whats the record for the loudest single 18? anybody know? thats an insane score, ik darn well my q never got that high lol.

box is amazing! lol and i have never seen anybody cut wood in a nicely done up basement before lol. good job.

yea i didnt think it could b the tune bc even a tune at 35 hz wouldnt sound bad. what program do u use for ur calculations?

I hope you mean highpass (subsonic) at 29 hz and lowpass at 80 hz. yea thats what i meant. and ik the box needs to have the sub subtracted, but the re program doesnt have that input so i made the box on the bigger side to bring it to about 1.3 cubes after sub and port, and the sub just doesnt perform well all around. i put the sub facing up and it still sounds like crap but a little better, what im thinking is that maybe the plywood i used was crappy so its flexing...would that be a possibility? square port area says 21...im guessing inches, and the total port length is 31.

im thinkin maybe i should build another box...i really think it has to be the box, bc the other box i had it in sounded alright, just had the port firing towards the side and didnt hit the lows, i figured if i tuned it to 33 hz where its supposed to be, and fired the port to the back that i would sound better.

low pass filter is set at about 29 hz, the high pass filter is set at 80. bass boost off bass eq all the way down, and i havnt set the gains yet, but its probably around 900 watts. the amp is a hifonics 1610d.

idk it kinda sounds dull, not very loud, almost like its blown, but i gently pushed in on the cone and there was no scratching or anything, so i dont think its blown. it sounds like there is a pretty good sized leak in the box, but i felt all around and no air coming out anywhere but the port.

hey guys, i used the re box calculator to make a box for my 10" fi bl. the box is 1.457 cubes for my sub after port displacement. the port is tuned to 33 hz. it doesnt sound good at all. i followed the cutsheets and everything and there is no leaks in the box that i can find. im just kinda wondering why it doesnt sound good. also, i used 3/4 inch mdf for everything but the baffle and the back. i used 3/4 plywood for that. could that be why it doesnt sound good? please any help would b great. thanx.

i would leave it as an option, so if somebody wants to have an inverted sub application, it will look a little better.

the remote wire is hooked up to the power antenna wire on the indash...i have done this before, so when the radio is on it sends the signal to ur amp but when the cd player is on there is no signal being sent, bc the antenna isnt being used.
