I was busy doing my run, didn't have time to record myself. But I do have a scoresheet rofl

TL results are in... Mic at headrest, passenger window down. 146.7db at 38hz Hopefully new alt will improve score

Did Sean (Shizzzon) make the video?

No there is no way and why would you wanna do that ????? you only will damage your batteries and also you wont get more power outta the amplifier 14 volts is the best voltage for the amplifier our amplifier they make power in low voltage you dont need do that here is a article about batteries, that goes to almost every brand Proper Way to charger your battery Yep yep yep. I personally wouldn't mess raising the voltage using a diode to the stock alt, I'd use a aftermarket HO alt with either an internal regulator or vcm. But either way, some stock vehicles charge past what Jefferson just said. And even my older car does sometimes... So is the website correct with the 9v-15v operating voltage, or is Jefferson correct, and the website wrong? Not trying to call anyone out, but it has to be one way or another, and the website makes more sense... I don't think he contradicted himself... He stated 14v was best.. But the amplifier has a range in which it can operate... Just like if he stated 2ohms was the best to run the amplifier at but it is rated at output for 1-4ohms.... Just saying... I reread and this is what I see: OP wants to run amp at 14.8v+ and Jefferson said you cannot do that. OP later states that the amp cuts off at 14.7v so that means the amp can't be on any higher voltage and Jefferson was correct So the website just shows the wrong max operating voltage then...

IB Sorry I just had to. I'd have a box builder make up a design But it just comes down port area (circular vent instead of square. just (radius^2)*3.14 ), and port length for tuning.

Traditionally for a 12v system it would be exactly 14.4v charging but often times that's not the case.... A 14v system would charge in 16v range, etc. I believe the 7k2e amp is designed to be ran on a traditional 12v system, and their max operating voltage is somewhere around 14.4 or so (I don't remember off hand) but even some stock 12v systems charge slightly higher then 14.4, and then most high output alternators have a slightly higher voltage... so the OP is asking if it would be okay to run it on the slightly higher voltage (14.8v in his case). Figures... I just went on the stetsom website and for the 7k2e - 1ohm amp, they show Supply voltage: 9 to 15V which sounds right... but Jefferson just contradicted that.

I'm just going to say: most high output alternators have a slightly higher voltage, like 15v So according to you, I couldn't use your amplifiers because my alternator charges at too high of a voltage... And no I wouldn't upgrade to 16v... Don't need stepdowns for a daily vehicle. But I guess 7kw of power may not be daily either... Hell even my stock alts voltage varies. In the morning it'll be in the 14.9range, during the day it'll drop to high 13s...

yup i think i am feeling better about it, i just ordered it, i just hope that im not one of the customers that seems to wait a month or so to get my alt and when i do get it, i hope to god that it fits lol I certainly see some people get theirs in a few days, while others takes weeks or even months. I know when I ordered mine, it took about a month, but it wasn't that bad considering it's a custom built product. I ran a saz1500d with no additional batteries, my voltage would just float around in the 14s like no big deal

Then it sounds like your covered

yeah i know they make an amazing alt, and its really my only option for my truck, but the website is kind of making me doubt wether or not im buying the alt that fits my truck or not I would definitely get a hold of them before ordering. Or order over the phone. Although it may take a couple tries to get someone on the line

It's a lot to keep track of on the site, and they are a super super busy company. Sometimes hard to get a hold of. But their product IS worth it. I promise you that.

wow thats weird, im glad you said something cause if you look at this page https://www.dcpowerinc.com/alternators/xp-series.html which is the page right before the actual item, it lists the alt for 629.00 I see what you mean, that is weird. One price on the listing, another on the actual product page. I'd also double check that they are the same alt types for the same vehicle. Just because it says dodge and or jeep doesn't mean they are all the same (although they vary well could be) I know for 50 bucks I'd get the slightly bigger one.

Price difference between the two listed alts is $50.

I'm digging all the new stuff

F that, you ain't getting my picture

These work? You want any pictures of drivers being installed or in enclosures (like showing members rides and stuff) or is this professional like backdrop behind the product, etc.

Great idea

Well I just plugged in google maps, from tucson to ft huachuca. So more or less. And actually I'm moving out to our new house in vail pretty soon, so that's right off the freeway

So for those that don't know, CrazyKenKid lent me his hyperdynamics meter (make it louder) so I could do some testing (I hope this doesn't get everyone and their neighbor PMing him though... Getting it here was a pain, USPS lost track of it, said it was at one office then another, then on route, then no idea. Finally got it though!) I've read that these meters are fairly accurate to a TL, how accurate? Not sure, guessing within a db or two (at least in the range I'm playing around in). So take it for whatever it's worth... Mounted mic on left side of windshield, vehicle sealed up. 36hz 147.75db Didn't write down the other sealed up results because my voltage was dropping after each run, so the scores couldn't be consistent. Mounted mic on left side of windshield, passenger window down. 36hz 148.76db 38hz 149.66db Voltage drop was pretty bad, low 12s, and high 11s for a few seconds. Going to charge the batteries and do a couple more runs tomorrow, perhaps I can get it a tad higher.

Your about an hour and half away from me. I could probably drive out and help for a few days

so smart

Kids so young, still got braces...

I know the feeling. One way or another, it should turn out well

Nonsense
