tis_LEXUS

Within the next few weeks, I plan on getting a 2000-2002 Lexus GS 300. Im young so I like my music loud. I really know nothing about the stock sound system in the GS. So I was wondering what would you guys put in there, as far as: speakers, what amp to push the speakers and also what sub, how many what kinda box? I know many of you guys have different set ups and I just wanted to know what I should do. Oh ya the price limited is around $1,000 installed. As far as the head unit, my friend is selling his Alpine TV/DVD combo, so Im thinking about picking that up from him cheap. So let me know whats up
