    Couple things

    1.Why do you want to tune at 35hz for a comp, your 45 hz tune will almost always be louder, most vehicles peak in the mid 40's.

    2.How do you know your tuned at 45hz, where your box is loudest is NOT where you are tuned

    3.What sub/subs are you using, a layout of you setup could be a little more enlightening (sounds like 1 15, but IDK)

    As has been mentioned, where the box is tuned doesn't necessarily mean that's where it will peak. What you'll need to look for is the half-wave of your vehicle (which is likely 40-50hz range) then tune the box accordingly to make a peak there with whatever sub you're using.

    Do you own an SPL meter? Where's pics?

    question 1. I have been told that 33 hertz is the sweet spot for spl and sound quality so i went with 35 hertz
    question 2. i had my freind test on it on spl meter and DB topped at 45 hertz with 127.8 on a 1600 watt qatum audio amp
    question 3. i have one 12 inch digital design 2500 series i now have pics up of my bulid on my profile under my images

    If you lower the tuning 10 hz, won't you lose some spl?

    Okay guys i moved the box up to my back seat out of the trunk cuase the trunk is sealed from cabin being a luxury vehicle. It made differnce in pressure its at the point where you get that funny feeling in your ear but only at a certain hertz for about a 7 second window and it drops down again

    You don't need a 2k you need a real amp. You have a quality sub but overrated flea market amp.



    bought from MBROOKY, johnny law.Lulz, subzero, tc3k101
    sold to mytrunkslamz , vitveet, cd6551, martiandancer31 (x2), pro-rabbit, whytellyou
    Trade with cf2004
