I am planning on getting one of those high power alternators off of ebay the one that at 1800 RPM will give me 180 watts, will this help dimming lights and what not due to electronic upgrades?

 

yes, that shoudl fix all of your power issues

 

but do i have to worry about getting a cap or anything?

 

Yeah it'll work. How much are they? I bought 1 from 4alterstart.com for $299, but it has a lifetime warranty.

 

Well i saw it on ebay with the 4 guage cable for i think 270 shipped 180 amps max and about 80 or 90 at idle.

 

yea its the same one..

capacitors are not for resolving long term voltage issues, they are for times when the current is drawn so rapidly that there would be a voltage drop if no capacitor was in the circut. with any subwoofer setup i would recommend a capacitor, but its not really nessasary untill you start drawing huge ammounts of current.

 

ya but i am syaing if i put in an alternator like a super high power one like i am getting will there be a need for a capacitor?

 

it still depends, there can stil be momentairt voltage drops caused by peaks of bass in your music that a capacitor would help smooth out... the issue with capacitors is how close they are to the amp.

so yes a capicitor would still be useful, but you prolly wont miss having one unlesss you are pushing a lot of power, or havea very discerning ear

 

Ha alright thanks
