My electrical is struggling...what to do to save it

Well I've had my system for around a month now and it's starting to put some real strain on the electrical system. When I get a real loud song on and put it at my ideal volume, my lights literally shut down, battery light flickers on, and car even seems to slow down a bit //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif A normal song plays fine, but things like Showstopper and Late Night Tip kill it. Im going home for thanksgiving break, I was planning on doing the Big3 at this time, will it be enough? If not should i go for a better battery first or a better alternator? I just found out my lexus can take a bolt on 130 or 150 amp alternator from highlanders and sienna's.

Lexus stock battery/alts ftl. lol But try the Big 3 first, I would go with an HO alt next, a Bat is nice but if ur alt cant keep it charged it's pretty much pointless cuse it'll still just keep draining.
