T-6 M-2 B-8 is what I am currently running. raise treble for a bit more air and sparkle, keep mids down because it gets a bit shouty at some midrange frequencies and add a bit more bass and midbass. The stock audio system is a bit lackluster. The speakers are the weak link in this chain. I highly recommend reading the SQ car audio threads by XtremeRevolution. He provides a lot of insight on the stock system and what he did to improve it. I will be doing a similar build in the next few months.
