And they are measured in farads, there are all kinda of crazy mathematical formulas you can do to correctly optimize the caps size to your systems pull.

I was once told by a audio shop that a "rule of thumb" that they used was 1 farad per 1000W of audio power.

I had a 1.5 farad cap on a HiFonics Brutus 1000 and never had issues with lights dimming or drastic drops of battery voltage.

Just my 2 cents :)

- Mon Oct 18, 2010 6:23 pm #218837 rockin a 1 farrad cap... wattage wise im doin 2000 supposedly but wattage can be innaccurate in my opinion. i like to measure in amps by adding all the fuses up 30+30+30+40=130 kinda thing but the stock alt puts out 70. the cap WILL fight against sudden losses of power but it doesnt turn a 70a power supply into the MINIMAL requirement of 130a.
wich is why my alt died.
but ever since i put in the high output shits been off the hook! and no loss in hp when i crank the stereo. bumpin and drivin fast! :hehe:

- Mon Oct 18, 2010 7:36 pm #218853 you can buy the stuff to rebuild your alternator from the dealer.

i had that done. i think all cost 25$ for the materials. i got it rebuilt for free cuz the bro works up there.

Really? I didn't know dealers sell parts. I assume most of the time, the coil is the part that needs changing and the wires.

yeap. should be people in town that can rebuild alt/starters etc.. also.

i forgot what goes out.

but if you have a system in your car and constantly having tons of bass and what not i would just go aftermarket alter that can handle it. or a capacitor

I had heard that too but that was for older cars. with newer vehicles which have way more electronics 1 farrad/ 1000 watts would be the minimum you'd want to run to be safe on the alternator.
