voltage drop, any change needed?

[blimblam 10+ year member]

at idle, i get exactly 14.0 volts. but when the bass hits, it drops to around 13.0-13.5V. thats not too bad of a voltage drop is it? should i do a big 3 or anything? the only problem with the big 3 is that the alt is very cramped up and hard for me to get to. so should i just do the 'big 1' or 'big 2' and leave out the alt?

get those readings and come back at us. Doesn't seem like a huge loss though
