I just received my SSA Icon D2 sub today after a longgg wait, between the box, and then the sub. So I am anxious to get everything installed, but I don't want to make any mistakes.

I've been looking at this wiring diagram to wire it in parallel to 1ohm.

And then from the manual

I am planning on wiring it like the top picture. I'm a little confused by the diagram in the manual, I can just connect to 1 positive and 1 negative, right?

I will set the gains using the stickied tutorial.

What should the subsonic filter and LPF be set at? Are these lower and upper cutoffs for what frequencies my subwoofer will play?

Bass boost and phase should be set at zero, correct?

Are these the proper settings I should use?

subsonic filter - all the way down

LPF - ???

bass boost 0

Phase 0

How am i supposed to know what frequency I'm setting the subsonic filter and LPF at if they just have a lower and upper limit labeled?

I don't want to mess up my first sub or amp.

Thank you.

I did try searching, but didn't find what I was really looking for.

Yea just wire it in Parallel. On the sub just do

+ to +

and

- to -.

Then get a piece of another wire from Positive Terminal of sub to positive to amp and Vise Versa with of Sub Negative to amp Negative.

LPF depends on your taste. 80 HZ or below.

Subsonic depends on box. Ported? Tuning? or Sealed?

Bass Boost -0

Phase doesn't matter too much

Sorry I left out some details. It is a ported box, tuned to 32hz.

If my headunit (pioneer deh-p6000d( can define what frequencies are sent to the amp, can I just leave LPF turned up to a high frequency?

How could I set the LPF to 80hz? i was thinking to just play a test tone at 80hz, and when I hear it playing through the sub, the LPF would be set ~80hz.

since you are using a ported box tuned to 32hz your sub sonic filter will also be set to 32hz!

Also i recommend setting both your amp and h/u to LPF to 80hz, that way if the deck loses power and you lose your settings and forget to change them back you will be okay b/c the amp is also set!!

with the SAZ1000d amp i believe to set the LPF at 80hz jsut turn the dial straight up (half way)

i hope that answers your question!

You have to just kinda guess at the crossover settings since they're only labeled on each end. Also, the crossover's aren't a brick wall. They're just attenuating slopes. So if you have a 12 db/octave crossover and set it at 80 hz, 160 hz will be 12 db quieter than 80 hz. But you'll still hear it.

I will try the LPF set straight up, thanks for the info. I actually have an SAE-1000D, but I would assume it is the same setting. Any suggestions on how to set the sub sonic filter to 32hz? Is that also a slope like the LPF setting?

Subsonic is a filter that "filters" frequencies below a Hz. Since your box is tuned to 32HZ then you can set it around 30Hz.

I was curious how would I know that it is set at 30, or 32, or wherever? The knob just goes from 10hz to 60hz

Id try to set your SSF around 23-25Hz.

The subsonic is just a highpass filter. Just guess at the location. It doesn't have to be exact. Just somewhere probably 25 hz is what I'd do.

Sounds good. Thanks to everyone for their input.

whats the optimal range to set a sub sonic filter for a ported enclosure: 1-5Hz lower than tuning of box, 5-10Hz lower than tuning of box or 1-10Hz lower than tuning of box?

I have heard them all and see everyone saying something different so I though I just ask and get this out the way for me and eman88 or anyone else who wants to know.

It depends on the tuning frequency of the box, there is no set value. Reason being that the frequency that the subsonic is at is the -3db point, not the point at which the rolloff begins. So, since an octave is a doubling or halving of frequency and as you increase frequency octaves grow in size, you can't use a specific number. It has to be relative to the tuning frequency.

But for most boxes, since they're mostly tuned in the 30-35 range, 5 hz below tuning frequency is fine.
