Well here's the dilemma.
I need someone with the stereo know how or in the business to help me formulate a mid to high quality sounding sound system.
I need help designing a sound system for my project. I've been studying stereo systems stuff for a few weeks and I'm no closer to actually making any hard decisions. I have a general idea regarding the quality of components I'd like to use, and some basic parameters I would like to pay close attention to in the setup.
It seems like the local shops only want to make up a system that will benefit their bottom line and not necessarily a quality component set-up that sounds good and does what it's supposed to without being obnoxious and overpriced.
In an effort to keep costs reasonable, I was thinking about using a single 5-channel amp to run the system. After talking with my local stereo shop, they had some discouraging comments regarding my rookie system design attempt. Here is what is was looking like...
Soundstream TRA800.5 5 Channel TRA880.5 $589.98
NUMBER OF CHANNELS: 5
OUTPUT (WATTS):
Channel 1+2: RMS @ 4 Ohms 60x4+200x1 to run
------------------MB Quart ReferenceRCE-213 $175.00
Channel 3+4: RMS @ 2 Ohms 120x4+400x1 to run
------------------MB Quart Reference6"x9" 2-way component / coaxial
------------------system with .75" tweeter$229.00
Channel 5 :RMS Bridged @ 4 Ohms 240 X 2+400x1 to run
------------------10W6V2 JL Subwoofer @ 400 Bridged $275.00
Amp Specs cont.
T.H.D.: < 0.02%
Frequency Response (Hz): 10 - 50k
SIGNAL TO NOISE RATIO: > 115dB
DAMPING FACTOR: >500
INPUT SENSITIVITY: 0.15 - 12.0V
CROSOVER SLOPE: 12dB
CROSSOVER FREQUENCY (HZ): 50 - 5k
DIMENSIONS (INCHES): 10.75x2.6x21.5
Total so far........$$1270
I thought an external active crossover was a necessity, however, my local dealer pointed out that the MB Quart mids and highs come with their own passive crossovers and the amp has crossovers built in as well for the sub-woofer. Are these sufficient? From what I've read, external propietary units are better for quality sound, as long as you can avoid importing system "noise" by using them.
One possible crossover I've found was a Linkwitz-Riley circuit unit from..
AudioControl 6XS 6-Channel Electronic Crossover / Remote Level / PFM $258.35
The head unit, a Kenwood KRC-3006, limits my system design due to it's weak performance parameters. I need to make up for the head unit with through the rest of the system. The head unit specs are in the top left portion of page four on this document. Sorry I couldn't figure out a way to post just a page of it....

I’m not opposed to running multiple amps except for cost concerns. The local shop suggested a muti-amp setup to optimize sound quality and performance. If I can get 3 quality mono amps for approx the same amount of $$ as a single 5 channel then it's feasible. But if 3 amps is going to triple the cost of the set-up then I'm not liking the possibilities. I've searched high and low for a "System Design Service", but they just don't seem to exist. Perhaps this is related to the number of variables inherent in tackling this sort of problem.
This is a start...I'll add more as I get it today.
Anybody out there that knows this kind of stuff that could help a fellow enthusiast get the best for his money.
