So i intalled my old 10w3d4 2 10s in a sealed enclosure i had that i got to fit behind the strut bar angled up. Its just temporary i already had this stuff laying around. I also have 2 12" w6 but need to get a good box for them. But anyway these 2 10s w3d4s arent hitten nearly as hard as i remember. There running off a jl e1800d 1000watts @2ohm and 500@4ohm. The subs are wired at 4ohm. Those subs should handle 600watts with ease. But it doesnt hit nearly as hard as i remember with the same amp and subs. It also if i turn it up really loud the speakers start to pop i also hear a tiny rattle from one. But I inspected them before i put them in there old but they shouldnt be blown they were never over drived. But im totally unhappy. I mean it sounds clean and clear but it doesnt hit hard liek i remember. I mean i remember my vision blurring when these things were turned up. From what i been reading the box seems a little leaky that could be the problem or nto enough air space.

 

i was gunna buy a zenclosure box for it but i wanted to see if it would satifsy me before i invest money into them. But from the looks i think im gunna get the 2 12" zenclosure box. And im gunna get another jl e1800d and run one to each 12w6 on 2ohm. I would just use my one amp cause it puts enough rms at 2ohm. But its not 1ohm stable and 12w6 d4 can only be wired in a 4ohm load or 1ohm load. Its funny caue my cousin has 1 12" w3d4 and hes only pushing like 300watt rms and there alot louder my tens that are running from a jl amp with about 300more watts going to them.

 

Determine the internal volume of your box and run the Thiel-Small parameters of your subwoofer. Adjust the internal volume of your box for something like a Qts of 1.4 or higher. I'm guessing that you're looking for amplitude vice accuracy. Your box has to be 101% air tight - a perfect enclosure or else it's not a sealed box and the woofers aren't under control.

 

i must be a noob or something but whats "Thiel-Small parameters " ? How would i adjust the airspace? By adding poly fill. Also how can i check the volume of my enclosure im not sure what it is. I checked to find the leaks there coming from some of the screw holes it seems. How can i seal it up air tight silicone? Thnx sry to be a such a noob

 

what set up did you hav eit in before that you remembered this vision blurring kind of bass?

i know they are the same subs...but same amp? same car? same box? give some details on the previous set up

 

The only thing thats different is the enclosure the other one i had them in was extremly leaky and it stil bangged really hard. The one i have them in now is newer it orginally had some cheap 10" subs in it. i took them out and popped in the w3s. i was able to wedge the box in behind the strut bar angled up it. Doesnt look all that bad either like that. But the old box was deeper i beileve but it was leaky. This new box is not as deep and 3 screws holes leak air cause there like stripped. And if i try to crank it up to max the subs start popping like im pushing to much power to them. But 500rms on 2
w3s isnt over driven at all.

Forgot to mention one thing orignally i thought my amp was 1ohm stable so on the old setup i had them wired for 1 ohm. And it worked unless i turned it really really loud then it would clip and go into protect mode. But now its wired correctly no clipping but doenst bang .

It used to be so loud in my old car it would out perform most peopls 12's and 15's no joke. It was serious for 2 miesly 10's people would think i had liek 4 12's lol. I remember the rear view mirror would point straight to the floor if i turned it up to loud lol. But then i bought 2 12" w6v2 d4 and then traded my pontiac and bought my 350z. And couldnt fit the twelves in plus i need another amp to push them properly
