[Dd1]

Try this , this guy came up with a method that works very well to calculate overlap setting.....    https://youtu.be/nV-_1f0Z-tE

[CC1 crossover setting after overlap difference.]

Actually I'm speaking of both. My gain is at -10db but when you look at any graph on lpf's they all show a range baseline at 0db well with gain overlap we set past 0db.

[CC1 crossover setting after overlap difference.]

Ok trying to better understand.  I'll admit I'm not 100% sure so try to help me with this lol. Looking at most lpf filter graphs you will see to the left 0db and down and at the bottom going a cross lpf range 20 to 100hz and 80 is chosen.  Well that's setting 80hz at 0db well we set with overlap at say 10db so at that level would we need the lpf to be set much lower to counter higher frequency cut off?  I'm looking like with 10db of overlap to be correct with 80hz I would need to set around 50hz to 56hz. Idk help me understand.  Because I set with 80hz on the money with the cc1 and sounds like shit but set with 50hz and sounds amazing, has this been overlooked.

[Amp with headroom how much gain overlap?]

Went with 0db track since the amp is over power 1500+ at 2ohm. was previously set at -5 and was way to much. In the future we may try -2.5db track but that much power over rms with   Potential clipping feels scary.

He must have had a reason for telling you that, can't say I know why.

Safer side would be the 0 overlap so I would give that a try, and if you don't hear any bottoming out then you could keep it or tune  it with -2.5 overlap and check for any bottoming out once again. 

Would you use the subsonic filter on the amp it's fixed 28db 12db slope, everything I see also the smd cc1 manual says 15's dont need sealed but I'm looking at the over power the subs will get would it hurt? Looking to get as deep as possible.

5 cubic net sealed box? Seems pretty big for those subs

Those P3s call for 1.58 cubes per, so 3.16 cubes, +/- some if you want to have the suspension move easier, but I think 5 cubes might cause them to bottom out especially with over rated power. 

That was what Forrest at Rockford recommend when we called him was 4.5 to 5 cube and I personally told him the t1500bdcp so was he thinking set the gain with 0 overlap I really wish I had asked him.

[Amp with headroom how much gain overlap?]

Also the Rockford PEQ remote is installed currently set to 0, was told would be needed because running a sealed enclosure but not using until amp is set correctly.

[Amp with headroom how much gain overlap?]

With a Rockford t1500bdcp @ 2ohm said rms is 1626, subs two P3 15's d2 in a sealed 5 cubic net sealed enclosure. With that setup what would be the best gain overlap 0db or maybe -2.5db? Sealed box range is 1.5 to 3.0 cube per I'm at 2.5 per dont wanna really chance over power and kill them. Any help would appreciate.

[Noise in system from remote gain control]

I had an issue with the gain knob in my daily making a "thud" noise with the subs and it turned out the knob was actually a little loose - I could move the knob a little bit back and forth and it would make the thud noise so I just disconnected the knob and haven't messed with it yet.

Strange mine does it on the amp side, I really only like having it for the clipping light.

[Noise in system from remote gain control]

I’m using the remote gain control and at high volume I get a thud sound from the subs, also does this any time the system is on say if I pull the wire that’s plugged in to the amp any. So I’m guessing the bass moves the wire . Is this common? I have use a few different wires all do this.

[Gain overlap over power]

I have a set of 2ohm focal components 80 watt rms power kr2 165 on a Rockford p300x2 should I even use any overlap ?

[When will DD1+ be back in stock]

What about  test Probes for the dd1 ? Need a replacement.

[What track when over powering subs?]

My box is 3.12 cubic net tunning from what I get is right at 40hz. So with giving power should I set my subsonic filter higher if I set at -10db track. With tunning at 40hz subsonic should be 30hz according to the manual.  

[Smd vm-1 stock]

Hope they come back by this summer, I have a smd om-1 in both vehicles now thanks to sonic electronic has a few om-1's in stock in case anyone looking.. I can't wait to ditch the stinger and get a vm-1.

I actually start with 0 to make sure everything is working on first fire up, then go to -15 and compare.  Work my way down from there.  if you are already over powering be careful.  Do you ever smell your coils??  I tried around -7.5 but seemed like too much, right now I am at -5.5 and it seems about right (thanks DD1+)  in spring since I've had this set up for a year at that time I may play with -6 and even -6.5  (and everywhere inbetween to really get it dialed in).  Keep in mind that EVERY set up is different, what works for one person won't work for you etc.  Watch the temps of your subs, voltage, smell, etc. etc. and if the subs sound like they are too over powered etc. etc.  just readjust.  Have you figured out what your rise is??

No still haven't figured out my box rise yet. Iam currently set with the -10db track 40hz and when getting at my max volume I can start to smell the subs so I'm thinking-7.5db might be a better choice.

[Smd vm-1 stock]

Any clue when the smd vm-1's will be available? Everything I have heard is that production has stopped on them . Tell me this isn't true.

[What track when over powering subs?]

Been rocking with it set with -5db for a while now does not sound bad but feels like the amp could do a little more. Would going to -7.5 or -10db be safe? With the scv 2000d I feel really probably just a hair more power than the older saz 1500d as they both use a 150 amp fuse. 

[What track when over powering subs?]

With given power the subs are seeing should the subsonic filter be set closer to the tunning? I went with what the cc1 manual said but a little higher I set it at 28hz low bass is pretty good just been going easy and haven't went full tilt yet. Most people telling me with the box tuned to 35hz to set the ssf at 25hz but I feel like that being maybe if I was running only the subs rms not over.

[Cab ultra same as a sundown sa rev3?]

So been seeing a lot on the new car audio bargain cab ultra sub and spec and price I can buy a sa12 for the same price I'm just wondering what sets the sub apart from the sa line? I know jacob sold cab the sa ultra sub rights but I thought the ultra was a a 1000 rms sub , most people are putting 1000 rms to say subs anyway with no problems. No hate or anything just curious.

[Sundown sae 50.4 on sa 6.5 cs v2 component's]

Would the sae 50.4 be a good choice for the sa components? I thought about running them passive on the amp bridged would that work well and would I need to run two sets of rca cables because I seen the amp does not havexist a bridged switch, would a splitter work?

[What track when over powering subs?]

So far the clip light on the remote doesn't even flash at all even at max uncliped hu volume now that's with the amp set with a -2.5db track, would just like to get a little more on quite tracks and some tracks feel like they could do a Lil more. So probably do at lest -5db and back down the sub level on the hu to be safe on loud tracks I don't like using the bass knob other then the clip light.

[What track when over powering subs?]

I dont see the point of overpowering your subs if youre contemplating turning down your amps gain anyway.

-7.5dB. Use your senses.

and like Kyle said, LEARN your gear and know your music.

Edit: I just saw that youre wired to 1 ohm nominal. You arent seeing much power at all. Dont be worried.

Wurd.... wired at 1ohm? fuck, use -10 and be kinda smart.

lower power with box rise? What kind of power do you think the subs are actually seeing then? Right now I'm set with a -2.5db track just feel like -5db might do a little better.

[What track when over powering subs?]

Well I know with track 3 -5db I shouldn't even clipping but with overpowering what should listen for to prevent damage?

[What track when over powering subs?]

Hi so running more then rms power to subs the subs are two sundown sa12's rev2 d4 wired to 1ohm on a sundown scv 2000d the subs have a rms of 600. I have a xs power d4800 up front and two xp750's in the rear and a 270 amp alt. Would setting the gain with the -5db 40hz track be the safest bet? Or should I set lower?

[Sa 6.5cs v2 component hpf setting?]

When I used the head unit hpf set at 50hz with a 6db slope I don't have no where near the output is have if I'm running full range. At 63hz with even a 6db slope I have almost no mid bass the 6.5 is hardly moving.
