Got it, I just enjoy super loud and clear sound with tight bass. I'm even less versed than you, but my local brick and mortar shop that's been around for 41+ years pretty much default advises me to go with CDT components and Memphis subs and sometimes Memphis amps for the few builds me and my friends have done with him. I don't know any better so I just trust his experience haha
But I'm impressed by your build plan so far and I've contemplated 6.5's or 8's in the past, and I talked with the shop about going that direction maybe 6-7 years ago but I don't recall anything other than budget at the time pushed me to two Memphis 10's instead of the 6.5's or 8's.
I just swapped out the Kicker co-ax's that came in my 04 when I bought it for my CDT anniversary set, with just 2" tweeters in the door for now, and WOW what a difference even without a speaker amp. I'm considering getting the Audio Control D4.800 you have for the DSP, and possibly going with 6.5 subs as well.
Are you going to do any upstage tweeters or are all the components going to be mounted in the factory locations?
