I got my 2 tight gap Z's in last weekend on a HD10k with stock DD parts. Roof is now made of jello

Murphy did, saying that they would be "better" than DD coils.

"Better" LOL. When Dante and Butler and them switch up to Tantric parts I might believe that. I can assure you DD has some R&D into those subs and if there was "better" they'd be doing it.

I had a giant box braced well, tuned low, with a lot of port area. I'm running two 18's, a giant amp, and it's sealed off. No idea what I'm doing wrong.

Have you clamped to see how much actual power they're getting? At least make sure you're getting max voltage out of it? Did you build the box to DD specs? I've seen a pair of 15" Z's doing 153's in a mid-size SUV below the window line. Sounded really good too. You're doing something terribly wrong.

Much hotter than any girls I've pulled so far.

Pics or it didn't happen.

I'm currently working out trade details with someone for a ton of 16v batteries. Then I'm going to get my alternator externally regulated. At Christmas time, I'll have about $1,250 saved up and I'll buy an 18v stable amp. For my Christmas present this year, I'll just send my Z's in to DD for recones.

So a different amp that'll make 25-30% more than rated power by adding a few grand worth of 16V batteries is your silver bullet to get loud? Naught for nothing but stepping up to 16V is for when you're sitting at 159.7 and want to try to squeeze a few more tenths out of a few grand worth of amps..... at the point where simply doubling power by buying more amps isn't cheaper.... or if space for more/bigger amps is limited.

Also, if the subs are "perfect" why send them to DD for new parts?

I'd get the subs back to DD and let them recone them. Then go from that point, going 16-18 volt is not

Going to just get you louder. Fail the plan, plan to fail .

I've seen a pair of 15" Z's do well into the 50s in a large SUV with an amp from the same manufacturer as his with half the power rating //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

You want more power than a 20k on 2 3" coils for music? You're going about this wrong. Z's can definitely be musical subs but not on that much power. They will take that for burps and maybe a 30 sec music run but not much more.

If you want more power on music, you need more coil. Whether it's moving to 4" coils or more subs...

And don't be one of those guys saying you're only using full power for burps. You're tuned at 27hz in a box that's huge. If you were going for numbers it would be a lot different. If you want numbers shoot me a message and I can give you a rough idea of what I use and also what a guy with your same vehicle doing low to mid 160s on 2 18s no wall did

Murphy did, saying that they would be "better" than DD coils. He could have ordered the "correct spec" coils, but chose not to. They're standard HDD coils.
The subs work, and the girls I demo'd for today sure liked them. I am disappointed that I can't do a legit hairtrick though. That was my goal.

I had a giant box braced well, tuned low, with a lot of port area. I'm running two 18's, a giant amp, and it's sealed off. No idea what I'm doing wrong.

I was listening to my truck in the school parking lot, and they walked up looking at my truck. I'd never talked to them before, but asked if they wanted to hear it. Two of them got in the passenger seat, and the other didn't want to actually sit inside. They liked it to say the least //content.invisioncic.com/y282845/emoticons/fro.gif.c695f1f814b01c4ad99fe7f8cccadd29.gif

Much hotter than any girls I've pulled so far. Might talk to one of them in the future

Ok, cool. Let me know


Yup

27hz tuning might be your problem or part of it. Volume and port area seems OK.

You mean to say you can't play a few sine waves at max power and get a steady AC voltage reading across the speaker terminals of that amp (be super careful not to short the DMM probes!)? Just checking voltage should give you an idea of if you need more gain or a pre-amp. I've heard reports that Brazilian amps like a very strong input signal (5-8V). By all accounts that amp should be making a lot of power for you.

16V is a TERRIBLE idea. You're literally doubling the cost of batteries (or more) which need replacing every 3-4 years anyway for what? 25% more power than the same amps would do at 12V? Buying a second Taramps 20K + doubling your current battery bank would be less money than just ramping up a battery bank to run 20K some other way. I'd guess that just doubling up your current battery bank NOW would get a lot more power out of that amp. I don't even recall seeing it but I'm sure it can't be enough.

The point being a good amp will last for a decade, a couple more Z's would last even longer... batteries will last 4 years if they're great batteries and you're lucky. Not a particulalry sound investment. Hell, even going to dual or triple alternator would likely be more bang for your buck. OR invest in super cap bank. Electrolytic caps should last well over 10 years. In short, 16 V battery bank will be a worse move than dealing with Tantric!

And seriously, kid, don't come on here bragging about pretty girls with no pics for proof. Might could well be they were a couple 350 pound beefalos or possibly trannys I saw you over on /b/ looking at all those chix with dix threads..

Don't be hatin' on /b/...

Other than that. I agree.

Yup. Scam.

Did you ever fix that guy's Kicker amp?

The not to.

Oh really? I wonder who that could be..........

I'm not going for numbers, I wanted hairtricks and loud lows

I wanted low tuning with a large box and lots of port area. If that's not going to accomplish what I want, what should I do differently?

You mean to say you can't play a few sine waves at max power and get a steady AC voltage reading across the speaker terminals of that amp (be super careful not to short the DMM probes!)? Just checking voltage should give you an idea of if you need more gain or a pre-amp. I've heard reports that Brazilian amps like a very strong input signal (5-8V). By all accounts that amp should be making a lot of power for you.

I didn't take voltage with a sine wave while the amp was unloaded. I just checked max voltage and max amperage on a couple songs. I've got the subwoofer level on my Alpine headunit at 7 out of 15. I listen at volume 23 or 24 out of 35. Gain on the amp is about 1/3. Any higher on any of those settings makes the clipping light flicker, unless I lower something else. A few songs at soft clip makes the coils heat up. A playlist-worth of songs at soft clip, and there is a hint of glue smell. I don't ever run anything too hard or abuse anything. Input voltage is steady between 13.6v and 14.0v. I need to get my alternator externally regulated. Even with the amp off, the max I charge at is 14.0v cold.

16V is a TERRIBLE idea. You're literally doubling the cost of batteries (or more) which need replacing every 3-4 years anyway for what? 25% more power than the same amps would do at 12V? Buying a second Taramps 20K + doubling your current battery bank would be less money than just ramping up a battery bank to run 20K some other way. I'd guess that just doubling up your current battery bank NOW would get a lot more power out of that amp. I don't even recall seeing it but I'm sure it can't be enough.

I have five group 49 batteries currently. 80 ah each, so 400 ah total. My battery bank now isn't a problem. After the 16v batteries went bad, I would just switch to caps. Caps would be easy to charge at 18v. I would just need more capacitors per bank than standard 12v banks.

I thought about buying another 20k. They can be had much cheaper now.

The point being a good amp will last for a decade, a couple more Z's would last even longer... batteries will last 4 years if they're great batteries and you're lucky. Not a particulalry sound investment. Hell, even going to dual or triple alternator would likely be more bang for your buck. OR invest in super cap bank. Electrolytic caps should last well over 10 years. In short, 16 V battery bank will be a worse move than dealing with Tantric!

Ok, I'll probably get another 370 amp alternator and have them externally regulated. Later in life after these batteries are done, I'll get caps and run a 16v setup with some Korean or Stetsom amps.

And seriously, kid, don't come on here bragging about pretty girls with no pics for proof.

I have sent pics to a few members on here. Posting pics will obviously get me banned.

How'd you know???

If you add another 20k you can kiss those coils goodbye.

Also, AH means next to nothing on a battery. Cranking power or burst power is what you need to look at. 5 small batteries on a 20k is actually not as great as you think. I have 4 northstar g24/34 batteries and 500a worth of alternator power on my 10k.

My suggestion if you want lows and hairtricks is to ditch the Z's and go with more cone area. If you have no desire to compete why limit yourself to 2 subs? You can fit 6 15s in that vehicle and could hairtrick and kill lows on very little power.

Fitting 6 15's takes precision woodwork and knowledge to use glue.

Have you seen this boys door pods?!?! Far from what i just described!

I been telling him to buy wardens. Buy you some wardens. You won't hear a difference and they are available all day. And tune to 33hz or so this time. Also ditch the Brazilian power. Please. Guess what all the really loud people use???? Not Brazilian amps brah. Sorry.

Sounddrive;

Jeremy Kough used xs8k's and wardens to do his 60, matter of fact wardens won a ton of classes at finals this year. Almost half of meca honestly. All the DB Revolution vehicles had V1 wardens in them, I used them, my buddy used a V2 warden and won.

You don't need Z's other than to say you have them

Both are loud. No sense in swapping between the two. For his goals it's silly to try to put 40k on 2 subs no matter what the subs are - for anything other than raw SPL that's not going to work.

And no one that's loud uses Brazilian? You should know just as well as anyone else that statement is false. You don't see a ton at finals because most people are wired under 1 ohm. Senchez used Brazilian amps (I know he didn't do great this year, but on 4 subs in an enclosure designed for 6 subs a 62 isn't bad). I agree that the T series aren't as good as the new ones, but the HD10k like I have are great amps and plenty capable of doing the power a Korean does for half the price or less.
