Question Capacitor placement question.

I'm pretty new to the whole car audio scene but I'm learning quickly. I just have a quick question. Where would a capacitor be best; between the battery and distribution block, or, between the distribution block and the sub amp. Thank you.

you have R * I^2 losses from the distribution block to the amplifier. any charge that the capacitor holds will be subject to this loss. better to put the caps closest to the amplifier.

Great, quick follow up question. Is it just the subs that benefit from the cap? Or would a second cap between the distribution block and the amp powering the rear speakers help at all?

im kinda new too car audio but i am going to school for eletrical eng....
wouldn’t a cap only be benifital if you were putting to big of a strain on your alternator? IE. When your subs hit your lights dim, so you put a cap in to help give that amp some extra juice when it needs. If this isn’t happening is there any benefit to a cap at all? Like I said, this is from an ee student perspective, not a car audio expert.
