[91accord4door]

hey guys i have a 920 watt kenwood amp and a 1800 watt power acoustic fubar. they go together very well my only problem is at nigh when i have it turned up a bit the lights dim. i just dont want to burn out my alternator. so does anyone know what size capacitor would be best for this application. i cant have my headlights dimming. my interior lights dim to. all of the lights do for that matter i know its becuase the subs draining the power. when the base hits the lights dim....etc. info please. so what size farad cap.? thanks.

i think its 1 farard for every 1000 watts... someone correct me if i'm wrong

kenwood? hehehe....just put a 1 farad cap i think you will be fine.

might as well buy the amp kit cause it comes with a distribution block etc

it should... i was talking to an audio expert that came to my work one day... and he said the best way to stop dimming of lights was to upgrade your alternator to a higher output one... but thats what he told me i am by no means an expert in audio

a capacitor still wont stop your lights fromt diming. i have a 2 farad cap on my single 1600 watt amp, and my head lights and dash lights still dim. look into getting a higher output alternator. get one off ebay u can find one for about 100 bux shipped. speaking of that, i still havent upgraded mine.

damn he beat me to it

Yes its one farad for every 1000 watts. Upgrade the ground wires first and then the alternator.

[91accord4door]

will do thanks guys. off to ebay.

kind of an obvious thing but sometimes it needs to be pointed out the ground wire should be equal size to the power wire...

[bruno8747]

I need a High output alternator also and Well tonight I have been looking at some. Whats a good rating one to get for a 1k watts RMS system with NO cap?
And Alternators from 90 to 97 are they the same? or are the only ones the same are the ones from 90 to 95?

i hope your running ot gauge.!
1 farad / 1000

i saw some h/o alternators on e-bay for 200 + i was thinking of just getting it rewound..but im unsure if thats the way to go..

[91accord4door]

im currently using 4 guage power wire.

i think you need something a bit thicker than that for your application!!! at least 2 or 1...
