POOOOOOOWEEEEEEERRRRR

:D

the diesel ones are 70 amp if thats any help, they are expensive though cos they have the vacuum pump attached to them :(

I NEED to get 3 EXTRA batteries in the boot, to power 10Kilowatts of bass. I wanted to know how long my OE alt. would last, and as Austin said, I wouldnt get a decent charge on the extra ones anyway. If i only uprated the alternator, and no batteries, i wouldn't get anywhere near enough power to my amps.

wouldnt it be better to uprate the alternator rather than batteries anyway?

cheap ;) ya know!

Yeah split charging three in the back of the car and am gonna have about 10KW of bass in there, opefully will beat the 150 mark with this one :lol: Will be interesting to see what bit of my car gives way 1st.

Two Yellow tops for 130quid :D:D

Corb mate, mines just started to show signs of giving up... Like you I have a 55A alt. Ive had my car 3 years since new and only put a REAL system in it 2years ago along with a single Optima in the boot. Recently my altenator has started 'ringing' whenever their is the slightest load on it!! I KNOW a 70A one will fit and I know the 120 Vectra job exists but I dont think it will fit without custom work... Let me know if the 120 will fit as I need to upgrade SOON!

well ajays can supply me with a 120A one for about 160 quid, for the corsa.

do u reckon thats what i should upgrade my altenator to when i get my isntall done? I dont wanna have to pay loads for a special one! (i will be running 2x 1000w rms subs somehow, probably with an audiobahn 2400w rms @1ohm amp)

Find someone who got the AEA1266, which is a 120amp alternator used in the tigra and vectra.

Yeh for defo.

A guy down at halfords with a car full of phase linear gear is running 4 redtops with a 100A vectra alternator in there. Dont ask me how he did it, i didnt think it was possible

120A alternator do it?

Its gonna struggle, and i dont think its gonna give the batteries a decent charge.

Ive now got my other 2 yellow tops, how long do you reckon my standard 55A alternator will last, charging my standard 300CCA(approx) battery up front and 3 Yellow Tops in the boot?
