Audio Diagram.

ok i think i have this thing figured out. after a couple days of searching i have decided on the onkyo se-90pci sound card. it seems to have good construction/reviews, is low profile, and supplies l/r rca outs. the line driver i bought prior to deciding on building a car pc just happens to have a 2 in/6 out setting. so heres what i'm thinking:

any thoughts?

hmmm... geuss 3500 worth of top of the line gear isnt high end enough. anybody care to comment from a sq pov?

I read your post yesterday, and it's all great stuff (better than I have BTW).

But IMO car audio SQ at that level is mostly about install/tuning. Show it to me in-car with some graphs from a calibrated mic on system response, then you'll get some feedback (probably more than you want

)..

i don't plan on going to far into tuning (running passive) and the install will be pretty basic (VERY well deadened, woofer in stock location, tweet in kicks, sub in proper ib install i.e. trunk welded and sealed off). the idea is to have a great sounding simple install.

oh btw, what i'm most concerned about is the onkyo sound card. everything else i know/can figure out.

Sorry no offense by moving your post(s). Maybe my definition of "high-end" in the carpc world is different.

To me I expect to see more advanced topics of discussion that merge carpc and electronics/processing/acoustics.

I saw a basic question asking about a soundcard/hardware and if it fits your goals then go for it. If you don't need a line in on the card perhaps a "USB DAC" might be another route if you are looking for a purist/simplistic approach.

I'd probably look into the usb dac's in your instance since you're doing all of your x-over after the soundcard. another option, if you want to expandability is to go with the behringer 2496

i checked out some of the behringer gear per your suggestion and i do like it, but i dont want to run another power inverter (my electrical is already complicated enough).

what makes a usb dac better than the dac built into the onkyo card?

unmolested signal mailnly. higher voltage outputs too

cay you explain what you mean by "molest the signal"?

just by comparing specs (which i loosely understand when applied to sound characteristics) the onkyo card has a high s:n, 24b dac, and high sampling rate (up to 192kHz).

*edit - the voltage isn't a huge issue as the ssld6 has a 1:4.5v ratio (13v peak).
