Box Build - If I remember correctly, it's somewhere around 12 cubic feet (after displacement) and ported to 35 hz

looking good so far, did you pull 150 out of it? I know I've heard it's tough to hit, but 2 18's shouldn't make it too difficult, they box is holy schnikes HUGE, 12ft^3, I did a 15 recently that's 4ft^3 @33hz I thought that was big!
I really love the way you did the ports.... this is just a suggestion, I know your box is already built but if you build the ports side by side, I hear you can pull 7-10 extra db's off that, might keep that in mind if you have trouble, but with your box build I don't really see any other way you could do that, so it looks really nice!

Got it metered lastnight and I'm super happy!! I hit 150.3!!!

Thanks for the suggestion and not to be a dick but whoever told you that thing about 7-10 extra dbs stuff is highly mis-informed (think about it...3 dbs or somewhere around there is almost twice as loud - so your saying by just changing port design I'll gain 2x - 3x ass much output?) I have to meet that person who told you that.

But anyway thanks for the complements! and would've loved to hear your system! 33 hz, must've been pretty low.

I see people post where if you move the sub around in your vehicle . . . you can corner-load it :p

None of them have ever bothered to have theirs metered ;) and then shown the pic of the meter , like you have !!

Very nice looking !! 150 dB :eek:

I built a box for my buddy for 2 memphis mojo 15s, right over6cf and he does a ~153 with a dd amp. I think 6000 watts he changes **** as often as his clothes. he was doin ~151-2 with a memphis 4kw.

Thanks! I will admit that moving the box forward and backwards in the car will increase and decrease your TL score but not as to gain that much. :D and I know what you mean, i always run into those comedians...LOL just take it in stride, it's all in fun. Hey if it works for your setup, great!

That's a great score! anyone in the 150+ playing music is loud, no matter what setup they have.

My friends just set the Hawaii State record with a 149.4 with a single 10" and a 152.4 with a single 18".

sweet score man! Now whats are you planning for the SQ system?
I'm planning on working on my CRX, I got some Zapco C2K amps with (4) Alumapros 12" and Rainbow Profi 3ways.

Still working on my wifes car, so it's on the back burner...:p

Thanks! for the props guys!

Love my dd's :) I've pulled a 149 on the glass. I know its capable of a 150, but its too expensive to find out if I blow something up :)

Nice install bro.

How do you tame it for normal listeneing? bass knob or gain pot?
