Need help powering vehicle + accessories?

ok heres the skinny. i own a 2000 gmc yukon with hid lights that need very high start-up power or else they both wont come on without turning them offand then back on-2 solo baric L7 15's with 1farad cap and a hifonics 2000watt monoblock amp with an epicenter- pioneer indash touchscreen-replaced all four door speakers with hifonics 6.5's and 2 tweeters in the front-plan on upgraded the interior lights,tail lights, and clear turn signals with leds, and install hids in the fogs. and later i wanna add speaker pods for at least 4 more 6.5's with a highs amp. dont kn ow if this makes a difference but ts been retuned with a superchips programmer......now after all that has been said heres the deal. sometimes my lights want turn on when starting, i have to turn them off and back on. my lights also flicker when the bass is up sometimes but not as often as before the 1 farad cap. my door speakers dim alittle also when the bass is up making the words drown out. im currently running a everstart maxx walmart battery and stock alternator. i dont want to do the big 3 mod nor the second battery mod. what other option do i have to do to get more power. id like to do an optima yellow top and an ho alternator. what alt. should i go to without having to modify something else, and shouli go with a yellow top or another brand.....on a side note im also thinking of switching out my 4 ballast for my hid lights from 35watts to 55watts. im not really looking for a direct answer, just opinons from expiriences or facts. thanks for reading the long post.Need help powering vehicle + accessories?
