My system:

BMW 325i 4-Dr 2002
McIntosh MX406
Audison SRX 3
JL Stealthbox/8IB4 in rear deck
Focal 165 V3E 3-way in doors
Dynamat everywhere

This system has been purchased but not installed. Install will be with Custom Sounds, Austin, Texas, whom I know and trust, though I had to buy the Mac elsewhere. I am sad to see that Nakamichi is no longer an option (it's been a while for me). SQ is everything for me. I am not crazy about the Mac look, but I am crazy about performance, and I want my DIN box full of important things like good D/A, and transport, and not wasted on unimportant (to me) stuff like amplifier, cartoon generator, DSP etc.

I want my signal going through as few things as possible between the source and the driver, but cars being cars, I fear that I may need some outboard EQ, though the Audison does provide some flexibility. Would appreciate general and specific thoughts on the above, and particular EQ equipment suggestions.

Why don't you use the Mcintosh MDA5000 D/A converter?

Vincent, I did not know of the MDA5000 D/A. What would it do with respect to my concern in the original post?

Greetings Thomas. Nice to have another audiophile on board.
i would strongly suggest te alpine pxa-h701.

I love it and have had no noise issues with it. it is extremely flexable. if ebay is your thing (that's where i got mine) they currently have it and the matching rux-c701 controller for under 600.00.

it does eq for 62 bands L and 62 bands R (31 bands per 2 channels on each side. i have my 1" & 3" eq'd together, and then each 6.5") at 1st through 5th order slopes (6db-30db/oct). also, if you ever plan on adding an additional sub, it will allow you to switch on the fly between it and your 8" without problems. i loved the capabilities of my 9835, but then this came in and.. well, i highly recommend.
about the Nac, see scott buwalda. he has eastern connections (abroad) and can get quite a few high end lines. http://buwaldahybrids.com/

for trunk mounts, i would consider audiocontrol's line of digital eq's.
or if you're willing to pay quite a bit more, and jump to a new HU, you could go with the pioneer p9 pair. it has extensive DSP control/options (scott carries the japanese corozerria version http://www.pioneer.co.jp/carrozzeria_x/lineup/rs-d7x2/index.html)

The MDA5000 is an external D/A converter. I myself am in the same boat as you, i do not like my signal going though so many different things to get to my speakers. I do not prefer an external EQ AT ALL. I have never played with an MX406 (i do plan on it soon) but i would have to imagine that it would have a built in EQ adjsutament on the unit itself. Just my .02 cents
