I recently purchased a SSA Evil 18in sub, and a 3k rms amp. my first ever real set up so im pretty new to car audio. but i have a question and in need of advice. when i turn up the volume it almost sounds like the subwoofer is bottoming out or making a clicking noise. is this normal or do i need to lower the power on it. or  is there more to it than just that?

you can run a 6k amp on this sub and it'll handle it. who hooked up your equiptment? what amp, how's it wired? my 1st guess is, it sounds like you put the gain at max setting and possibly max bass boost which is 1000% wrong.

Hey Jason! yes from what i heard this sub can take a lot more than 3k, yes installed all my equipment on my own. the amp I'm running is a sound stream  T1.6000DL at .5 ohm, and i dont think it has a gain on it unless its called something different, but i will attach a photo of the current settings. sorry if its hard to see

id say my subsonic is at 3/4 of the way, and I'm not sure about the tuning but id say about 35Hz

Is input level and bass boost all the way up . . . . And is the sub not in an enclosure built for it?

My guess is the sub is in an enclosure that is not the best for it and you are needing to turn the gain and bass boost up for it to sound decent and its not to good on the sub

Input level=gains looks like its maxed out.

Bass boost looks like its maxed out.

Subsonic around 40? 

Headuniy settings?

Dono what box is or tuned to?

You would have done better if you would have turned everything to the left. Turn everything Down before you blow that sub.

Leave your low pass filter where it is.

 Are you a troll really ? Nothing on here is correct It's like you saw Jonathan pryce t-shirt that says turn everything to right and you did.

Let's start here and see what we can learn.

Yes, turn all that down and set it up right before you destroy your sub.  While you are at it you should share some details on the enclosure it is in...

I seen them knobs on the pic and this poor man has the pedal to the metal and wondering why the gears wont change. We will take care of you boss and make sure that the beautiful piece of art you purchased will be playing to its full capability. Please share enclosure specs with us. LxWxH and port length and dimensions aswell. Since you shared pic of amp maybe pic of box aswell? Also your voltage at half ohm is taking a beating. Whats your volts stay steady at while you were playing?

I would even turn the low pass filter down, even though pots arent accurate. Looks to be low to mid 100hz, but everyone above already touched on everything else. Good luck

low pass 1/4 way up , gain 1/2, bass boost 100% if you have a knob,  subsonic off

haha no I'm not really trolling this is my first set up, pretty new to this, i turned bass boost all the way down, and turned the gained and subsonic down, sounds healthier now. I'm guessing it was doing some major clipping? does it a little still on the high notes ill attach pictures of my electrical set up and box specs

Who makes the alt and have you clamped it for accurate power? Ebay 250 amp needs to be at like 6k rpm to reach it. Just want to make sure you got stout power supplier.

So does it sound as loud and clean as you hoped it would ?

Try turning the low pass filter down, find the song with notes that still give you trouble and use that as a gauge. Anyway to go to a reputable shop to get you set right?

      A brief introduction to the all new SSA Demon, but first a farewell to its predecessor. 
           Our very long running SSA Dcon has ridden off into the sunset, or at least taking a breather.  The SSA Dcon was our second subwoofer model we ever launched.  At the very beginning, we had the Icon and as it gained traction we saw there was a need for a pure SQ sub of more modest power rating than that the Icon.  So in early 2008, the first SSA Dcon was launched.  (The Xcon followed shortly after).  That being said, the Dcon was almost an immediate hit, with a long 2" copper coil (rarity to have one made in the USA) triple stack motor, rear vent.  The Dcon was very affordable, well made, quite efficient, clean across the entire range, and flexible with enclosure demands.  It is interesting as there are some SSA Family members who swear by their Dcon and will not give it up ever.  (It even became a favorite of some of the home audio crowd).  All that being said, the Dcon evolved a bit for its second generation, we made a leap forward in motor force moving to what is best described as a scaled down Xcon motor, with a large single slug, solid pole, and deeply bumped back plate, while beefing up the suspension and leads.  We were able to bring the power handling up 33% while not hurting the sound that made the Dcon successful.  There was a stretch of a few years, before we ran out of stock, that the SSA Dcon 12 was our all time best selling subwoofer.  So its existence was very important to SSA.  Well with changes in the market (read:customer demands and amps getting much cheaper), as well as sky rocketing material costs, building the Dcon in the USA no longer was an option, so production stopped early 2017 for both the Dcon (and Gcon) and inventory ran out later that year. 
           Late last year, due to the long lay off with out the Dcon (and Gcon), we started development of an updated Dcon at a new build house.  The quality and performance of our SSA Evil1 tweeters were above our expectations, so we decided to send more production to that same build house.   As we saw that the market slowed overall for modest power rated subs due to power getting cheaper and people wanting higher power handling subs, so the market began to really start heating up in the 500 - 1200 watt range, I knew we needed to address it.  There is an 8" model developed, but it will not make it this first production run.  
           The new model had to handle more power and have more xmax while not sacrificing the balanced and clean sound the Dcon had established for nearly a decade.  That meant larger motor, larger coil, more suspension, larger leads, thicker cone, taller surround, etc.  In the end, all of the changes that happened to the over all design, we could no longer call it a Dcon.  In sticking with the theme of the Evil, a model name that has become so well known, while respecting the Dcon, the Demon name was selected.  The Demon is a great blend of the previous Dcon and Xcon, both in design and appearance.  In prototype testing, the SSA Demon thrived smaller to mid-sized ported and mid-sized sealed enclosures.
      Quick SSA Demon stats:
      2.5" copper coil Aluminum former Aluminum Shorting ring Solid pole, non-vented bumped back plate Large single slug motor Pressed pulp cone Tall roll surround Push terminals Dual Nomex progressive spiders Stitched tinsel leads Large dome dustcap I will list T/S specs and enclosure recommendations shortly.  We are very excited about the SSA Demon as it bringing back to our line up a pure sound quality subwoofer that will be affordable, while still having the characteristic SSA warmth and output.

      Hey guys manzkea back at it again! Lol. Finally got some equipment in. Excited to finally get this project I’ve had in mind for a while rolling . Gonna attempt a blow through in my single cab 2001 ford ranger long bed. Gonna make pods for the doors to house the 6.5s and replace the stock one with a 6.5 or if possible an 8” driver. All powered off the ssa ic150.4.  As for subs I’ll be using a 15” sp4 v2 I got from a friend for a deal. A taramps 5k will be used to push it.
      Unfortunately the evil mids I wanted was unavailable in 4ohms. So I went with these prvs.
       
      Well I’ll I’ll be updating this as I get it going. Possibly next week or so, really busy with work at the moment. Well here’s a pic of some goodies the mail man dropped off.  Cheee. 
       
       Btw got something extra special in those two ssa looking boxes behind the ranger gear. But that’s on the back burner at the moment.

      Slow build, but wanted to get a build log going.
