good question, if you have a sealed(4th order) does it matter where you set subsonic? I have a general ideal of how it affects tuning on ported boxes,

supercharged hummer h2

8 Sundown nightshade v'2 Scott Bowman built 4th order bandpass

2 precision power pcx 4125(mids & hi's)

2 Stetsom 14k2e's

alpine ina-w910

dual Mike Singer350 amp alt

8 kinetic 2400 batteries two shuriken bt 120

1 kinetic 2000 under the hood

I thought you knew everything? Just the other day you were throwing out the best brands etc, but you cannot set a filter? alright

I was tought it should be where box is tuned?

Sure, that should be a foolproof (fool's way) of setting the subsonic filter.

I'm pretty sure you can easily find how to do it properly.

Tip, it doesn't involve a secret formula or a rule of thumb, nor do you even need to know the exact tuning of the box.

Thinking is the root of all problems...

You ALWAYS get what you pay for.

Google is your friend

Thanks alaskanzx5 I might just do that
I can recone a sub myself. About a year ago I took 2 12" power acoustic mofos and made one sub. I took the magnet and the motor off of one and j b welded it to the other motor and magnet. I had to wind my own voice coil so it would work. After I was done hooked up to 2 boss 5000w amps. And shattered my back and all my side windows

came to this thread to recommend soundqubed and ct sounds. OP goes with soundstream.

oh lawd.

not sure what all the fuss is about.

i barely even have a subsonic level BUT i dont go full tilt when i know i am playing below box tuning.

how low do you play? i would set it around 23-27 htz. but it all depends on the box volume, tuning, and power.

i need more info to give you a better estimate.

edit: BUT

edit again: ok now that i understood myself and learned how to read properly, I see that you are tuned to 34 htz.

i would set your subsonic at half and call it a day.

and if you hear your subs bottoming out on lower notes raise the level more or dont play full tilt below box tuning.

Oh i know how a 12v system works I did take 3 years of electronics in High school hands on and some in college and also worked on cars in college an always got A's to B's in each class. 

But oh well enough dealing with ppl who have probably not even lived as long as ive been into electronics!
