Bigg Boy Posted December 27, 2009 Report Share Posted December 27, 2009 I still say one voice coils is wired backwards. disconnect one coil, and see if it gets louder.

Cigarz Posted December 27, 2009 Author Report Share Posted December 27, 2009 (edited) i would look into wut ben said All I have in EQ is: Treble, Bass & Fader Treble @ +4 Bass @ 0 Fader @ 0 Yeah I went over the manual and nope no other settings, my deck is 2.2v I believe. I think that's all, I suppose I might have hidden options on the deck but I honestly don't think so.

Marlo Stanfield Posted December 27, 2009 Report Share Posted December 27, 2009 It's prolli a combo of low power, poor enclosure(not just that it's a prefab, it's very small for a 15 making it even less efficient off that little power.. If you had at least a larger pre-fab enclosure you would see a difference, let alone a properly built one), and settings likely aren't correct among other things. What are the box specs for that pre-fab?? Quote 1998 Ford Explorer Eddie Bauer... New setup, old ride... QX56 is staying stock til I get loud...

Cigarz Posted December 27, 2009 Author Report Share Posted December 27, 2009 (edited) I still say one voice coils is wired backwards.disconnect one coil, and see if it gets louder. What do you mean? I have one wire going from positive on one coil to negative on the other than i have positive and negative of each coil going into my box terminal, same to my amp.... I already checked my feeds, and they're connected so I dont know... I guess tommorow I can take the woofer out and double check, couldn't hurt I suppose... It's just going to be a pain in the ass, im almost 100% sure I did it right, think one of my coils could be blown or something maybe Fi messed up? honestly I don't think that's problem though, I honestly think a lot of it is my amplifier 400RMS isn't exactly a lot on 28.28v I think a lot of people running 400RMS are boosting their gains and dB up without people known.... it could also be because my subs not broken in. Heres my box: http://cgi.ebay.com/SINGLE-15-SUBWOOFER-VE...#ht_3022wt_1165 Dimensions: 21" W x 16-1/4" H x 18 D 1/2 inch MDF or 3/4 didnt make much of a difference on the calc and I think its about 2 - 2 1/2 inches of port Port length probably 14inches (vertical not horizontal theres no edging in the box.) No matter which way I put the dimensions the box is tuned out under 40hz.

Cigarz Posted December 27, 2009 Author Report Share Posted December 27, 2009 (edited) According to REaudio box calculator im running between 29-33hz on this box so how could it be the box? even if the port was 3 inches shorter than my guess or so it's be 33hz if it was longer than my guess its 29hz... Wait I just realized the way they measure port length is after the port goes in it then turns right for a few inches... my port doesnt do this its just a straight narrow port STILL though with 0 extra port length on the calculator im hitting 36hz thats still pretty friggin low... eigther way my box is tuned below 40hz wayyy below 40hz like mid 30's.

Mendozauly Posted December 27, 2009 Report Share Posted December 27, 2009 Check your ground maybe your amp is not getting good ground, also try to by pass your EQ and go direct to your head unit. This is only to make sure your eq is working good. Make sure your rca's are in the right input. Sorry but some time's it's something very easy. Also make sure your sub wire's are making good not to small of a wire.

I don't know what you're saying, the EQ should be fine its a new deck. I checked my RCA's if my RCA's are reversed how will I know, will it make a big difference? I kind of just randomly put them into the amp lol. Sub wires are good just put new ones on it today, they are pretty small but shouldn't be too small for the amount of power im running to the sub.

Torres Posted December 27, 2009 Report Share Posted December 27, 2009 it doesnt say how long the port is...but either way...that is NOT 3.4 cubes of airspace like the auction says it is. use those dimensions, multiply them, and divide by 1728 and you get close to it, but that is counting wood displacement (unless those dimensions *are* the inner dimensions). which is a no no, that's not usable airspace. it's 2.75 cubic feet of net volume after wood displacement, but before port displacement. i dont know how wide or long the port is, so i put 2" as a minimum, and to get to your mid 30 tuning that you say you're at, the port has to be 30" long. which gives you 1.81 cubic feet of net volume. after displacement. just fyi...that's incredibly small for a 15". it should be double that at LEAST. the box i had for my 4 15's was ~16 cubes net, so about 4 per sub. imo...i know you dont want to believe it but the box IS the single biggest problem in that install right now. when i say an enclosure is 80% of an install...i'm not exaggerating.

The box seems rather large IMO it's almost as big as the box that was running my two 15's before... I have a hard time believing its not on par with 3cubes, but I mean im no box expert. So what you're saying is my sub isn't moving because of my box? and im losing 80% of my bass because of it... wow. According to your box calculator and what I've seen inside of the box I should still be under 40hz... but I see what you mean i've seen 3.5cubic boxes and they are bigger than mine... I should re-measure the box to get actualy dimensions...
