    sub amp is blasting wide open/freaking out

    I had a scarily similar issue, had the thing mounted on an amp rack but fastened to the enclosure. It was an enclosure that I built while in recovery from a major stroke and my fabrication skills were lacking to say the least. The enclosure bracing internally came loose, just enough to cause some mad vibrations at higher levels. It (the amp) never complained until one day the same issue you're having arose... I was out of my head trying to understand why the amp was making what sounded like a weird 40-60hz tone at full volume and went to pull the amp and was ready to crack it open when it finally died and I saw this... Anyways... the board had walked 1/8" out of the heatsink so I contacted CAB and shipped it off as it was still under warranty at that point. User error for sure on my part but happily in my case covered. You probably have some other issue hopefully. I just thought I'd throw that story out there, I ran that amp hard... .5, .67 and 1 ohm but it was my diminished fabrication skills and choice of mounting location that killed that amp. I thought I had the thing built right but apparently while in recovery building enclosures is not a good idea

    DUAL Skar Audio ZVX-8

    Personally I wouldn't waste my efforts on a pair of 8's (no matter what they claim)..... I'd try to increase cone and look for a way to load the port correctly so it'll be a one and done. Something like this will let you pretty much put some decent power to the subs and if you choose Sa-10's it's a no-brainer... your limitations will be port area and knowing your equipment. You got the space, seat lift and all... I say use it. My .02 Back to lurking
  3. Available space measurements are always key... including what'll go thru the opening not just what'll fit once in there. It's not the 1st revision I've had to do due to this issue... lol... if you'd like a new design OP, email me and I'll see what I can come up with. 30-32hz tune around 2.5ft3 net IIRC... correct?
  4. Specialists were pushing Stealthboxes? That's a shame... when I lived there in the 90's/early 2000's they had a "Hollywood shop" location right next to the Speedway store that some sweet builds came out of. Don't know if it's still in operation but those guys were OG and could do some really twisted stuff. I'd ask the store if anyone is left or if they could put you in contact with someone.
  5. Design A gets my vote for the same reasons as stated above. A smaller volume will lose a touch of output (less peaky) but I'm sure that was considered since you wanted a "SQish" response, and still some great lows. Here's another I did, the guy wanted to cover the box face with a fabricated removable grille, it's targeted for a little less power, a slightly flatter response with greater extension but really should be pretty much the same once in-car. Once again "A" gets MY vote... good luck!

    ZV3 15 box help

    I just whipped this up... See... no problem with the added port area and smallish volume.

    ZV3 15 box help

    Let's say... 3.75ft3 net with 63in2 of port tuned to 34hz for instance.... I dont see a problem designing something like that. Pretty standard IMO An 8" aero is gonna be a bit of a squeeze and for 3-3.5K might not be enough but is better suited for a bit less power Any idea of the actual dimensions you've got to work with?

    ZV3 15 box help

    I'd shoot for around 4ft3net at 34-35hz and 65in2 of port minimum for your power... 3K If your strapping into 1 ohm I'd go closer to 70in2 or a little more for the added power. If you got the room it should be no problem.

    ZV3 15 box help

    Go with an 8"aero... or 2 6" aeros for ported but it might get a little long... sometimes compromises have to be made. The 10" I alluded to in the other thread was for the 4th front end where length wouldn't be an issue and I like a decent amt of port area and the tune is mid 40's, the length shoulda been manageable. For ported you'll need to watch length for a mid 30's tune with 49-56in2 of port. Keep it around 4-4.5ft3 net and it shouldn't be too bad. As you have more room available idk if you'd consider a slot so compression wont be an issue cause of your power. Personally I'd go big on port area and smallish on volume with the power you've got. Aeros limit you to a set area but a slot can be sized. Something like this ought to work out pretty well... I coulda doubled-up the materials all around with the space you probably got available easily.

    Hcca 3k losing power at high volume.

    Port compression.... JK Sounds like a battery bank is in your future man

    Good luck man... I found out that doin' a pair of X-8's underseat for 2K with a slot meant a ton of compromises but turned out well... I had to rake the baffle just right to get clearance. Took some figuring that's for sure... That was with no trans hump to get in the way... Sa-10's were easier... same flat floor. Sa-8's shouldn't be TOO hard... lol Underseat boxes are a challenge to do especially with a slot port or getting enough port area/length with a transmission hump in the way

    ZV3 15 4th order, need some opinions

    I'd consider tuning a bit higher... say, 45-47hz... the output will increase and you said 3K plus correct? I'd try for more port area as stated, IDK what your looking for sound-wise but a slightly higher tune won't necessarily make the thing not go low. 49hz tuned in my Honda goes under 30hz but I opted for a smaller sealed and high ratio with a lot of port so I got that peakiness I was looking for, Heck it's only a 750 watt sub so I tried to get some decent output (even if it is an SA-15). I looked at yours... and for example, slightly increasing volumes to 1.9/3.8ft3 and tuning to say... 46hz for example might allow you to use a 10"as the port length becomes manageable. That much port sure won't hurt as the sub needs room to breathe (it'll be burp worthy... lol... +4Kish?)

    No subwoofer break-in my ASS!!

    Thats a 4" coiled Hi-power team sub... IMO you were barely tickling the beast. I remember quite a thread but save me the reading... whats your volume/port area/tuning? Sheeit... that thing looks like it needs 5K+ and a SUV to put it in. BIG box after the port area needed/tuning... wow
  14. 3k of input on 4 8's... wow... you'll need a lil' port area for sure on that, it looks like it's gonna be fun to find a compromise that'll work well.
