alternator in bravos?

[Sergio]

hey

what kinda alternator (how much of A does it have) is in a 1998 1.6 sx bravo?

Are the ones in a bravo diesel more powerful?

thank you!

bye

[Tom]

65A from memory.

I doubt the diesel one would fit.

 

[sergio]

well, i'd like to get sth bigger like 150A so I knwo I'll have to work on it to fit

 

[Tom]

You going in for SPL comps now?

 

[sergio]

nah, but i'm (if i get the job ) buy some more amps and it will pull a lot of power from my batteries so i need a bigger alt.

Let's say i'll need around 4500 rms @ 1ohm (+ around 600w rms for fronts, 2x200w rms@2ohm + 2x100w rms@4ohm) at 13,5V (hell, i'll be happy even with 13V ). All for daily, comps are for pussies

so i'd like to upgrade my alt.

 

[Tom]

Even if you had it turned all the way up, playing music would average about 1/4 those powers. Maybe 1/2 on a very bassy track.

1000W is easily within the capabilities of the stock alt.

 

[evo~paul]

Definately is possible, just wired up a 1000w @ 1ohm on a stock 1.4 alternator

 

[sergio]

LOL, i know it is possible, i currently have 2400w rms @ 1ohm only per sub and it's ok

but i doubt that it will still be ok when doubling that power.

 

[evo~paul]

what sub and amp combo you got at the moment then ?

 

[sergio]

at the moment

Resonant Engineering XXX 15 (1600w rms, 2500w peak, 2+2ohm)
+
Alphasonik PMA1200D -> 1200w rms @ 4ohm, 2000w rms @ 2ohm, 2400w rms @ 1ohm

1 of the pics which i took during the install

 

[evo~paul]

Good choice Sergio, me has a XXX 10"

I don't believe we can get AlphaSonik over here but we do have other beasts that can do 2000w +
I'll stick with the 1000 or so i have for mo (must resist temptation to buy bigger amp... must resist)

 

[Tom]

Paul, what was wrong with the SPL amp in the end?

Sergio, have you upgraded the wiring in the engine bay?

 

[evo~paul]

Hey Tom,

Sent it to fixmyradio.com and they fixed for me, next day . It was the short circuit fet (i think thats correct). They replaced and tested £59, bloody bargain i reckon !!

Hopefully weekend of the 25th i'll finally get my 0 gauge in and start distributing power to the SPL DIG-1450 and to my other Kenwood amp and i'll get my fronts amped up as well !

Looking at getting a scope of EddyP for £60 hopefully and i'll get everything setup correctly.

TOM:

not yet, i still have to the what "americans" call "the big 3 upgrade"

Paul: hehe, i owned the dig 1450 before, but sold it before i got my XXX as i tough it wouldn't be enoug But than again a friend has a Brahma 15 (almost the same as XXX, 1600w rms, a bit different motor and some other differences) and he says that he only needs 1000w

 

[Tom]

I'd recomend you do the big 3 ASAP, the charge wire on the 1.6 is tiny!

The engine and chassis earths are a reasonable size though.

 

[evo~paul]

Sergio,

For the XXX, 1600W is better i must admit but 1000W is plenty to get it moving for the time being. If in some point i can increase the voltage the likelyhood is the DIG-1450 should give me a bit more.

Tom

Are the wires the same spec on a 1.4 do you know, i do have it planned to upgrade all 3 at some point though

 

[sergio]

paul:

well, i was told by the seller of SPL Dynamics here (a friend of mine) that all of the dig-1450's that were sold here, were benched at around 1200w+ rms at 14.4V

 

[evo~paul]

Yeah i think its the same here, 1200 is good for my purposes and if i need more i'll just get another, as my XXX is quad coil, so 2500 give or take a few !!

 

[sergio]

I was also thinking about just buying another one as they produce 2500w+ at 2ohms bridged, but mine xxx is 2x2ohm, so I can only wire it at 1 or 4 ohms :S
