Just a quick question by running a 1farad power cap inline in thr stereo system does this not drain the battery at all when the car is left parked up?? I have no idea as never used one if these in a system before so all new to me

A cap (or capacitor) is just a passive piece of electronics.

It's intended to provide a large, immediately available reserve of power if the bass hits, or at least that's the theory.

A cap permanently connected will draw absolutely bugger all current to speak of and would take months/years to flatten a battery. Your alarm will do it much faster

Oh right thats great thanks alot for the help I can stop worrying now that im gonna get stranded with a flat battery.lol

cheers

p.s will post some pics of my new install i have built soon once i sorted the pics out

 

Probably not something that will worry you but if for any reason your car is having trouble starting, the cap will assist the battery in turning over the starter.

Two advantages in one!!!
Cool!!!

...but not if you're using a split charge or diode. Besides, 1 farad of capacitance at 12V contains 144 joules of energy... That's enough to run a 100W motor for slighly over a second.

It won't help starting

 

OK I guess it wouldn't provide enough energy to aid in the starting.

If you must be picky, I think you'll find that its about 72 joules anyway.

 

Damn, I forgot the /2 bit

 

No worries Nick!

I heard you were good at this sort of stuff!

;-)

 

I got as far as physics a-level but that was, oh, 12 years ago now

 

Well at least thats all cleared up now
I have my pics from the install i just done how do you post them on here as i have no idea?? would just like to know your opinions on it, well as long as they are not all bad that is.lol

cheers
