SNEAK PEAK OF THE SILVER FEILDER

[1MADE]

PPI + FI BTL

[jeff]

the pcx model and the pc model what changes were made
i thought this was teh older model

[viking1705]

wait til ulyuh see the monos.

[bass lover]

[certified_dealer]

loving the install, keep it up,

[southside connections]

i have always been curious how these amps do this power
and why the manufacturer's specs are "coherent" for only one of those amps and supposedly not the other 2

yes i know on the internet those specs are listed somewhere (300% less in the manual) im not saying your not telling the truth but just curious about them

good question , i have seen what you are saying there, what i did was estimate power at 12v, with the fuse rating at an efficiency of 70%


based on what i saw, the amps are quite capable of doing their minimum rated rms power

the pcx model and the pc model what changes were made
i thought this was teh older model

well i had a black ppi art a while back, and the same model in white, both amps used similar boards, but the quality of components were totally different ,eg the black one had higher rated outputs ect

another thing was the color of the components were very different


i'm guessing the same with the ppi pcx line which is known as the "power class pro" line, and it was their flagship line at the time of when ppi ruled the market

jeff if you can, please get the manuals i would like to see what they are really rated at

[southside connections]

is that how door dynamat is supposed to be done?

well it has 3 layers on the inside of the door skin also

[jeff]

when i saw the pic i thought they looked like the old ones
only to realise they are not so hence my confusion with the ratings because i had some of the older ones

maybe then u can explain how you are going to use time alignment in a gallery setup

[SEVin]

Look at Noise Pollution......I LOVE IT!

Cant wait to see more!

[southside connections]

maybe then u can explain how you are going to use time alignment in a gallery setup

ok, this is one of few things i will not discuss here, there are ways for it to be done just as in a sq car, same principal , different drivers

it will be used as much as possible via headunit and based on the fact it's a headunit with a 4 way x-over each filter having it's own independent time alignment figures

thats why the rta was bought, i cannot hear these little peaks and drops, but the rta can , and will show where and when

if you want to see the use of time alignment in gallery, i will let you know where and when we are tuning and i'll happily show you personally, otherwise i'm not discussing it here

but i can't help but sense some sarcasm there, but i'll let it go

SRRY TUNERS, THERE ARE FACTORS OF THE SYSTEM THAT WILL BE MENTIONED BUT NOT EXPLAINED, I DON'T THINK I HAVE TO EXPLAIN WHY I WOULD DO THIS

but i will explain certian factors, but not all, so feel free to ask questions and i will answer to the best of my knowledge

[noyztoyz]

maybe then u can explain how you are going to use time alignment in a gallery setup

i dont see how this question arised, please explain

isnt this a technical thread, he mentioned it so i asked
i dont think southside saw anything wrong with my question

[carfreak1024]

wayz boi, when this coming out for tobago or some, whenever this car hitting a show definately make a post to let fellas know nah boi.

This looking like it going to be devious.

i dont know why, but i have a sneaking suspision we going to see a 12" midbass, 10" mid, and driver on each front door, a 10" and a driver on each rear door. A.K.A. the baddest 3 way component set ever, lol.

I Have no idea how in heaven you are going to fit all that in a door if you going to do that eh but it will be cool to look at.


BUT I TOO AM CURIOUS ABOUT THE TIME ALIGNMENT IN THE GALLERY SCENE.

[pimptacular]

what hu are you planning on using that has the 4way x-over with T/A..unless i miss understood ur posts?

and y not explain everything? the purpose of build logs ideally is to share ideas so other people can learn from your experiences and share your knowledge wrt car audio not show off (not saying you are)..as jeff mentioned its a technical thread

example- my build log i didnt hide anything and explained everything the best that i could, and encouraged people to ask questions about anything they wanted to know about the system..

[SR]

maybe then u can explain how you are going to use time alignment in a gallery setup

i dont see how this question arised, please explain

bt this is a technical thread

so i do see the validity of jeff's question


i am also curious as to what is going to be time alligned and why

[noyztoyz]

i asked cuz i didnt see where he mentioned time alignment, ill go read back a little.

[audiopipe]

the magnet on the fi looks a lot like the magnet on the re xxx

what brand of rta u got ?

[southside connections]

got a dbx^^ with a condersor full range mic

works great so far

i dont know why, but i have a sneaking suspision we going to see a 12" midbass, 10" mid, and driver on each front door, a 10" and a driver on each rear door. A.K.A. the baddest 3 way component set ever, lol.

nope, all midrange,midbass ect located in the cabin of the car, all doors are to remain stock

i am also curious as to what is going to be time alligned and why

due to the fact that a car is not a perfect listening environment, and also the 10" midrange and the driver units are being placed at different points , they will not be placed equally and the idea is to get the music to sound as accurate as possible, so we now have a problem with certain frequencies reaching the listeners before others, creating large audible gaps

remember we want the listener to hear each particular driver without being able to tell which is playing, thus by using time alignment we can correct each driver's position vs the the listener's position

also, it's almost impossible to get a staging effect directly in front of the car due to the windscreen , so it is decided to do the midrange system is going to be stereo

[ruffneck_12]

^tek out d flippin windscreen den

was d approximate cost of a system like dat?

[southside connections]

well lets see-

ppi amps -$16500
monos- -$17000
fi 12's -$11600
all mid speakers-$17200
battries - $13000
processing/hu-$5100
sound deadening -$7000
alternators- $8000
wires - $8000(inclusive of fuse blocks and copper bars)


well so for thats- $103400

serious question again, i am not asking this for myself, i am asking this for all the new guys who don't understand what you are talking about here, those who just see expensive equipment and say that makes a system sound good


in a gallery system where you are standing up 20 feet away, you are saying you are able to tell if the different speakers are in different positions?

[southside connections]

in a gallery system where you are standing up 20 feet away, you are saying you are able to tell if the different speakers are in different positions?

if it's inside of a car, yes, but what people have to understand is the fact that different drivers play different fequency ranges, eg, the n850 will be playing at 900hz to 25khz and based on ear sensitivity you will more than likely pick up on the horn first before the midbass playing

now the human senstivity-

http://www.independentrecording.net/irn ... tivity.htm

you can easily see when one can pin point each particular driver

the idea is to make each particular driver's range flow smoothly into the other creating the "meshing" effect

one thing i've learnt over the last few years, if you can look at a horn and a midbass, and point out when the midbass tops out and the horn picks up, then you have a problem

however there are only a very few vehicles i can recall doing this-

disruptive audio 4 12
green civic
atomic daddy
casper's b14
rovin's single 15

and lastly, sound extreem's blak vigo with the mtx 10's



however ontop a hood facing the crowd on the other hand is a different story

it is very rare that you see winning competition cars place their drivers/midbass units in akward places, very very rare off axis

$16500.00 spent on close to 2000rms of mids amps?

what does a normal old school rf 800.2 go for? not close to $2k?
you could have gotten close to 8 of those for that price & that 800rms * 8 = 6400rms (3 times the power).

why did you choose these amps? how do the power consumption in these compare to the power consumption to the old school rockfords? isnt it more? when building such a large system wuth such a large budget i'd look for the amps with the lowest current draw.

[DJ Q]

Remember this is a competing car and TriniTuner is a public site.

Honestly, a guy approached me last year in the MK Wheel Barrow show to tell me about all of SSC's builds and how he used the info that was placed on the web to make his car better.

So yea, I see why it'd be necessary not to release some information.

My $0.02

2000wrms? jack-

2200 pcx- 800wrms rated 12v
2200 pcx- 800wrms rated 12v
4125 pcx- 800wrms rated 12v
2400 pcx- 1600wrms rated 12v

what does a normal old school rf 800.2 go for? not close to $2k?

amps were bought new brand son, paid what the guy wanted for them
you should not underestimate the ppi pcx lines of amps, they are very very underrated, way more than you would think

why did you choose these amps? how do the power consumption in these compare to the power consumption to the old school rockfords? isnt it more? when building such a large system wuth such a large budget i'd look for the amps with the lowest current draw.

these amps were chosen because they are some of the few amps out there that actually do their rated power at a full bandwith , meaning there is no power increase/decrease at different frequencies

yes the current draw is more, but it's well worth every amp extra, but remember we also have the right amount of batteries and the right charging rate to accomadate them

remember i won't build a system this big to suffer from current problems

here's a look at the battery bank-

10 d1200 powermasters
2 300amp alternators(300amps at 2000rpm)

when the car is ready to play, i will raise the rpm of the car accordingly



now as for the question of using rockford vs ppi, rf would have been my second choice if i could not get the ppi, but for you to know a amp, you must use it

so what i recommend you do, go out, look for a ppi pcx line, any one and compare it to any other amp on the market with the same rated power, play them together, clamp them ect, and then see which comes out ontop

just for refrence, you can ask the seasoned installers here about the ppi line and if it has ever disappointed them-

fuzz
sr
jeff
silent riot

ect, do a pm and check back with your results

[nervewrecker]

& what kind of power the bass amps put out?

[southside connections]

the bass amps are to remain a secret man^^lol

To be honest what you doing shows great enthusiasm as well as encouraging others.
You are willing to try new things and do what alot of ppl are afraid to do.

BUT

one can never stop learning.

with this in mind you kind of have the right idea but the theories and deductions need working on, the new guys do not know this or even new customers

with this in mind, you need to do some reading on phase, iid and itd and zero plane delay.

otherwise looks like a promising build im sure the whole of the ice including myself wants to hear it and maybe u can bring it to the next test and tune

sq or gallery, does not matter... music is music.

Agreed,

btw, would this vehicle be in the show on sunday?

thanks man, need some more research to be done here but thanks for your input!!

btw, would this vehicle be in the show on sunday?

yes but unfortunately it will not be playing, it's taking in alot of money to finish off and were're only 1/4 way through
