Havoc 18 wieghs 35 lbs.

Awesome, thanks jacob

Ok, so back on topic.........

My stock alt is 110 amps, so it's no punk. my voltage drops to 12.6 on hard bass notes. I do have a 50 farad cap on the system though, so it helps a little bit. It depends on what size your alt is, I am having a very hard time finding one for mine, because of the way it's set up.

So, slightly less power strapped? What about efficency, i.e load on the elec system?

Yeah, I'm just an oldschool basshead. All my buddies tell me that I'm too old for that, but I say screw 'em.

I have 2 1500d's, only one is in my car right now. I have an AA havoc 18d2 in the car as well. I am looking to add another 18 soon. My question is: will I get more efficency and power with both amps running seperately at 1 ohm a piece or running strapped at 2 ohms? I have factory electrical(110amp alt) for now, will be upgrading it soon as well. I just want to run the 2 18's without destroying anything in my car. Any help would be appreciated.

How does american bass stack up quality-wise to sundown? Specifically the xd3000 to the saz1500? Any help would be appreciated.

Just got another saz-1500d!! It will drive the 4 tens I'm putting in my '79 TransAm SE... just gotta get a wire kit and I'll be good to install yet another system!! The car: http://www.soundsolutionsaudio.com/forum/i...si&img=2675 The subs: http://www.soundsolutionsaudio.com/forum/i...si&img=2672

Havoc 18....... 2 of em ....... yummers! If you havent done it yet, I would definitely cut a passthrough from your trunk, and box in any speakers on the back deck( if you have any). Those 18's will destroy any speaks back there not boxed in... trust me;). Remember to wrap those tinsels... I used some leftover walmart car-carpet and just glued them around the tinsels. <<<<----------Havoc 18 FTMFW!!

Thanks guys.. I tried to be as honest as possible with it.

Thanks guys.... btw, review is up

My bad, I assumed they made a 10, and didnt look at it first. With that being said they do make a 12 tho..........

I voted the 4 tens, but I would actually go with 4 AA Havoc tens... imagine those sexy cones all lined nice and purty like..........

Did you build a wall? how bout some pics?

The Pontiac g8 looks kinda tasty(only if it has a stick), also the BMW 135 seems like a ton of fun...Of course the challenger and camaro(not due till 09, I know )

Holy shnikeys!!!!!!!!!! Now you makin me want to get another havoc 18 and saz1500 for my car......

Ok, first off, all pictures are in my album, so I wont repost them(saves time). I Bought the sub a few weeks ago, to replace my 4 mtx thunderr 5500 10", powered by a saz-1500d. The shipping box was ok, standard cardboard box with the styrofoam pieces in it to hold the sub. I would have hoped for a better box, as I've heard and seen horror stories with that type of box, but oh well. Build quality seems very nice, not much excess glue, all joints well glued. 2 problems I have with the build quality, small to some, but annoying to me. First is that the terminals are extremely close to the basket, less than a millimeter apart on one side and about a millimeter on the other. My worry with that is obviously shorting to the frame and smoking my amp. second is that the tinsels are not sewn in to the spider. That didnt seem to be a big deal, as there is felt on the back of the cone, but became a problem later(at least to me). The cone is sexy, surround is strong, although it is a foam/rubber compound rather than a full rubber surround. Very healthy sub, wieghed in at 35 pounds. The first box I built last weekend for it was 7.5 cu ft gross(sealed). It is truly amazing, the kind of low frequency output this thing has. It makes the whole dash and windshield flex, and I dont mean just a little either!! Only thing about that size box is that there is very little upper subbass output. This is where the tinsel leads came in to play. For the first half hour or so of listening and playing around, all was cool. Soon after that I could hear a higher pitched clicking sound on harder beats. Figured it was tinsel slap but wasnt sure, so I kept it a bit lower all last week, because it did sound like a coil bottoming out as well. I have honestly never heard tinsel slap before, so that where that came from. Today I rebuilt the box down to 4.9 net cu ft, and it definitely loves that box!! I also took the opportunity to wrap the tinsels in some fabric pieces I had laying around, and that fixed the slapping problem. My mid-upper subbass came up, and it seems I kept all the low freq output too, so it is a win-win situation. Compared to my tens, it has the classic trade-off: lost punchiness, gained low freq, but overall I am very happy with this sub. I was able to make up for the punchiness I lost by upgrading my front stage to a pair of diamond d971's I installed a couple weeks ago, so it's no real issue to me. If you want to do 20-30 hz with authority... GET THIS SUB!! It is a very clean sounding sub, does keep up nicely with rock and roll drums and bass(in the smaller box), also blends a lot nicer with my front stage than the 10's did... definitely a nice LSQ sub! If I had it to do over again, I probably would go with the rl-p 18 though, only because of the tinsel issue( Yes it is that big of a deal to me!) Seeing as how I bought this sub without ever having heard one, it wouldn't bother me to get the SS to replace it if I ever needed to. Old box: http://www.soundsolutionsaudio.com/forum/i...si&img=2687 New, smaller box: http://www.soundsolutionsaudio.com/forum/i...si&img=2716

Rebuilt the box from 7.57 to 5.49 cu ft gross... 4.9 net. Whatcha think? http://www.soundsolutionsaudio.com/forum/i...si&img=2716

Awesome, Thank you

Yeah, thanks Devil, you really helped me out on that. See this is my first time messing with an 18, I've been into the caraudio thing since the early 90's, and played with 10-12-15" subs, but soon found that 10's were where it was at for me. But now, I wanted to get deeper, without having 6 or 8 subs in my trunk, so the 18 definitely fits my bill.

Would you please post the displacements of the havoc line(18 in particular)? Thanks

Home depot can do the cuts, I would keep it simple for them though. Try not to make too many angles and such. BTW, you should also consider ascendant audio, I'm a rock and roll guy, just bought a havoc 18", and loving it. I upgraded from 4 10's, and not looking back. Enclosure size is the MAIN determining factor to get the sound you want out of these type of subs...when you are talking sealed. I do not run ported, never liked them, so I have no suggestions for that route, but some of the other guys here do. Good luck

Ok, after messing around with the sub for a couple days, I have some info for all interested parties. My original box(sealed) was 7.57 cu ft gross.... 7.0 net after bracing and drvr displacement. It goes super low with authority in that size box, however for my taste not enough punchiness. Today, I filled the box with some wood scrap on the order of 2.1 cu ft, and the sub really loved that! It became punchier, with very little sacrifice to the low-low end. So, this weekend, I'm gonna cut down the box to 5 cu ft, and play with driver facing as well. Stay tuned to this channel........
