nvx vad power clamp tests around 13.5v were between 1750 to 2100rms after rise depending on frequency , rising to 2.3-1.7ohm , very good output for the size and price ! judging by clamp numbers i feel this amp would pass on dyno testing at rated power

check out my videos of this amp in action ! i have 2 vad27001 on 10 102 nvx vcw subwoofers walled !  https://www.youtube.com/user/mazda2284/videos

Xtreme Lithium Cells , scam / bad product

Xtreme Lithium Cells , scam / bad product
im making this post so that people can actually see the feedback on Xtreme lithium .
Xtreme ''chris'' removes any feedback on his page in hopes to catch another sucker .
one of these pics is feedback from someone that has been scammed but these comments will be gone as soon as xtreme logs on .
he has targeted car audio but now is moving on to target other hobbies like golf carts and boats and anywhere he can find someone to give him money .
below are a bunch of pics , Xtreme also claims to never had a battery fire but that is not true , one of the major fires in car audio was an xtreme battery ! along with many having burnt cells , burnt connections , melted plastic , dead cells , cells that were clearly damaged prior to assembly , ect .
not only is it a bad product but many have waited 6+ months before trying to get their money back and never getting a battery and in some cases no refund .
Car audio Companies even went as far as voiding your warranty if you run these due to the xtreme fail rate that can take out other products .
ive taken one apart myself and over 1/2 the packs inside were dead reading 0volt , it had proper amount of cells but less than 1/2 was even working . others have found less than stated amount of cells inside so there never was a chance of the battery being able to do what its supposed to.
xtreme even states they do not run a balancer and that lifepo4 cant start on fire which is completely false

if you would like to learn how to build lithium batteries yourself that are Much safer check out my group on facebook !

Actiontec T3200M Review and Problems

I recently received a new T3200M modem made by actiontec for my TDS DSL internet service . It was pitched to me that the new modem would have better speeds and have better wifi range supporting b/g/n/ac wireless and also support Bonded service .
the tech came to install the modem and it was fast and easy to setup , at first my download speeds were a little better but my upload seemed to stay about the same , about an hour after the tech leaves my internet cuts out and i get a red internet light on the modem , no big deal just reset the modem and good to go right ? well about every hour after that i had the same problem , internet would cut out and red light on the modem , at the time i did notice some problems viewing webpages and my games seems to be kinda laggy so i ran some speed tests and the download seemed to be fine , this continued for a couple days before we had our tech come back out on a friday and replace the modem with a brand new T3200M again , he also went through our house wiring to make sure everything was fine , while my tech was here to do the install he mentioned that he was installing bonded service just down the road from me and that i should call to get it setup so i could make use of the new faster service .  the new modem worked fine for about 30min after the tech left and the problems start all over again . being that he came on friday i could not have him come back out till monday so i was stuck with the problems all weekend so i did as much reading and trouble shooting as i could myself , i tried changing many settings in the modem ''disabled ipv6 , diagnostics , ect '' nothing seemed to help , as my speed tests looked normal i was very confused where the lag was coming from , i had a new computer sitting there ready to be put together so i built it with fresh everything hoping maybe it was just my computer that was the problem , the new computer still had the same problems hard wired and on wifi , at this point i was thinking maybe the problem was widespread and not just me . i called tech support to get monday setup for the service tech to come back out to try and fix the problem , while talking to them i asked about the bonded service and they told me it was not available ''odd because my service tech was saying he was installing the bonded at a house down the road from mine that is slightly farther out of town '' so monday comes around and the tech comes out and starts by just rewiring my house with all new phone and cat5 cable to my modem , we check it after the wiring is done and still same problems , so he goes down to the hub downtown and switches my port and checks everything down there , he comes back and still same problems but he brought a older T2200 modem with him , we hook it up and the first test is much much better upload speeds . problem solved ! so my overall review is that the T3200M modem just does not work properly with standard service , also i was told the wifi range and service was better with the T3200M and that also turned out to be wrong , the T2200 had much better range with my devices . 

pictures of the tests were test that finished , many tests with the T3200M would fail on upload . clearly the best test with the T3200M was much worse than the first test run with the T2200

How To Run your 12volt car audio in the house cheap and easy !

How To Run your 12volt car audio in the house cheap and easy !

Resonant Frequency of your Vehicle

To test resonant frequency you need a 10'' subwoofer in a 1.0 cubic foot sealed box , place the box in the center of your ride or as close to center as possible with the cone faced toward the back of your ride, test tones /sweeps , amp , and a termlab/spl lab /RTA . play sweeps at around 3/4 volume , find ur peak and double check by using single tones , make sure to keep the volume the same at all tones . this will give you the resonant frequency of your cabin , this is why the same system would sound totally different in a different ride.also if you have a big box you may want it in your car while testing because that can change things , also if you can remove your subs and cover the sub holes in your box with a sheet of wood as they can also throw off the final result .

Can a Capacitor Help in your audio System ?

Can a Capacitor Help in your audio System ?  Yes it Can help BUT you need to have the supply first . the main part of your electrical is the alternator everything comes from that . your batteries hold that power , your alt will keep you at higher voltage than ur batteries will . here is Test results from a Test taken on the AD1 Amp dyno by the man that Designed the amp dyno. In the tests a standard 1 farad cap. and Carbon 100farad capacitor were used . A Capacitor is a great addition to a Stout Electrical system and is not a Band-Aid for a Weak Electrical system . Capacitors can also discharge faster than any battery in production .
