How to tune pioneer 5000 watts spl

[groove_street_boys]

will upload the pics soon as its out of ma car nw ... m sad from ma SPL

Once you tuned it rightly....It might cause bleeding from your ears

waiting for tht bleeding

check the below diagrams, they'll answer ur question

if ur sub is a dvc here's how to run it to get min impidence (max power).

and if single voice coil u can't play with the impidence

[groove_street_boys]

is solid audio f2500d is capable of 1 ohm ??? my sub is connected as shown in 1st diagram

Yup it is

[groove_street_boys]

can any1 tell me how to run f2500d @ 18v???? as it produce 4000 watts at 1 ohm

help :(:(:(

[Durrani90]

well the thing is even in the 2500d is capable of 1ohm load, u wont get that power. the sub u've mentioned is a d4 and not a d2. meaning each coil has n impidence of 4ohms and ur current setup is giving the amp a load of 2ohms. meaning less power. to be honest ur amp is too weak for ur woofer IMO (im guessing ur getting about 1-1.5k watts atm). and maybe that is why ur not satisfied with the sound.
there a digital designs z1 amp for sale on the forums, i'd suggest u go for that. its capable of 3k watts rms on 2ohms (or something around this range). that will surely bang ur sub to ur hearts content

F2500D is beast bro.....It can easily play this sub!
Just all he need is stable 14.4v and good tuned enclosure......He is done!

[splfanatic]

bro let me tell u the problems

Firstly, your sub can only be wired to 2ohm atmost not lower than that, and at 2ohm f2500d will hardly put out 1k rms

Second, it will be a huge achievement for you to stabilise your electrical at 14v, what to talk of 18v

Your Amplifier, Electricals are too weak for managing this subwoofer, let me tell u a way out

Sale F2500d and get Oxygen Audio Mk2 mono as it peforms quite decently at 2ohm and get atleast a 150amp generator and a tuned box

Option 2, sale W5000spl, by 4 power efficient sub and run them on 0.5ohm on 2500d with atleast a 150amp generator

Option 3, if u dont like the above options sale everything and go back to car performance :*

[groove_street_boys]

hmmmmm so will go for 1st option ... but nw again it will take time to manage the dollars

Na new O2 amp is available in Lahore at jumbo electronics

Go sent sumone ur friend to pick it up .... Priced at around 23-24k

yes well there's a difference in a small beast and a large beast. do the math man, 1k rms from the amp and the woofer is 3k rms!! meaning under powered!!

i dont get the initial part of this, how come the 14v will be n achievement? or do spl systems tend to drop voltage?
i ask this cause im running a kenwood excelon amp and i get stable 14.4v (even when the car is idling) but then again it doesnt consume more than 40amps of current even when turned up really high.

p.s for the sake of knowledge, how is one to achieve an 18v current to the amp?

Voltage remains stable at 14.4v only if the alternator and battery combined can perfectly deal with the output power requirement

as the amp is question is f2500d, it has got 200ampere fuses and extracts alot of power from electricals, now how do you think a stock 60amp generator and 100amp battery will deal with ?

the alternator will fail to maintain floating 14.4, it will be all down to battery which will fight for 10-15mins to stay arnd 12v and then go kaput

Thats why mainataining stable 14v is an achievement for high powered spl setups and you need high output alternators say 300amperes

Now coming to the 18V question, its done mostly by competitors and in cars known as trailer queens not for daily driving strictly for competing, you need a peripheral alternator and battery backup with 18v output which is very expensive and its isolated from the main electricals of the car

Or u can use 18v electrical in car and regulate voltage to parts other than audio system but that can cause disasters as in insurance claims sooner or later Hope it helps

It's an achievement for a SPL guy ... Idling at 14.4v vary car to car ...bigger car bigger alternator ...btw which ride u got.

Spl systems drop hell ov voltage even to 10v in a start car... Strong the electricals lesser the voltage drops ...

Bro all is the game of rms and ohms ... Lesser the ohms more the power demand by the amplifier .... Means to go down from 4ohms to 1 or 0.5 ohms you need more strong electricals ,larger current requirements for the same rms

It's p=vi (14.4)(the current ur alt or battery can give)

Means for a 400rms setup u need a 400rms amp at 4ohms ...so to stay idle at 14.4v u will need current ...

So p=vi , 400=(14.4)(I)

So current req is about 40-45 amperes also taking the 80% efficiency of class D monoblock ...

So thats why u idle at 14.4v most all of the cars do...

But for a 1000rms setup you will need about 90 amperes the same way with abt 80% efficiency of class d amps ...

So my friend bigger the spl setup with low ohms ,larger the current demand and hard to maintain at 14.4v

And don't. Forget we are talking about a 5000spl which is 2000rms so think ur self the current demand and challenges to idle at 14.4v

Hope this clears out ...something from my side .

u knw nothing abut the f2500d

[groove_street_boys]

thanks every1 for sharing ur knowledge .....
now the question is how i will i come to knw the generator which m buying is 200 amp or 300
thanks
