SQ/ SPL system

hahahahaha sony and bose ...hahahahaha 

a new  question just came to mind...is there a big difference between the comp and ref series of zapco amps? because there def is a big price diff and if i could, id rather get the ref series amp for my components instead of the one that i originally posted

Hey Take that back !!!

sandt38, thanks for the info, but unfortunately....ur last sentence meant nothing to me cause i dont know what that difference implies...sorry but please explain lol

thanks

It's kind of like this----on a straight line, start numbering from 1 to 20,000.

When you're done with that, .....ok right, but you get the picture of how long that line is going to be?  Now, these numbers are hertz, a name for a particular frequency.  When you plug something into an outlet at your house, you are plugging into current that is alternating at a frequency of 60 hertz.  And when you hear your neighbor's car coming from next block, the car with the boom system in it, you are hearing frequencies of about 25 to 40 Hz.  Opposed to those examples, the highest pitch you could possibly stand to hear is at a frequency of above 15,000 Hz.

Anything below 20 Hz, you can't hear, you just feel it like a rumble.  The human ear can hear 20 Hz up to 20,000 Hz (20 kHz).  A good human ear, I might add.  The subwoofer in your system is going to produce that tiny segment of that line from 20 Hz to about 80 Hz.  And all the rest of the music, the next 3 miles of line, is going to be reproduced by the components.

That is why, when you want really good-sounding music, you put the money into the component speakers.

damn....great post man and thanks for all the info

also, do u not think that the focal 165K2 and the zapco comp amp for these speakers are good enough?...and do u think taht two subs, even if i get focal utopias, will drown out the music?

yea i know u can adjust the volume lol...i just dont want the bass to hit too hard but i guess i can go with 2 subs....it looks cooler too in the evo with this setup:  http://www.jivemotorsports.com/enclosures.htm

anyways...i thought taht with all the help you guys have given me...IN ONE DAY!!!!!!! lol...i should give you my decided setup:

HU: Eclipse cd8443

component speakers: focal 165K2

subwoofers: 2 Eclipse 10" SVC subs- aluminums

amplifiers: Zapco 350.2 and Zapco 1100.1

thanks again guys and im sure ill be back for more questions later

I do agree that you need to concentrate more on the front stage.  But one thing I have learned from experience is that more expensive doesn't always mean better.  An example is my $650 a/d/s/ components are sitting in my closet as we speak, while a $350 component set is in my car right now.  My system has been like this for over a year now.  The a/d/s/ components sounded phenominal, with the exception of lacking in midbass and rolling off a little early in the high end.  The components I have now are renowned for their midbass, and gained back that little bit of top end.  Plus their sound is just as good.

As for the subs, unless you need a small enclosure, I suggest jumping up to the Brahma 12.  The performance difference for the small price difference is worth it.  I'm not saying the B10 is a slouch.  In a local competition, I was able to beat out guys with dual 12's or 15's.  It's just the price difference is very small, while the performance difference is noticable.  As for dual subs, two Brahma's are pretty expensive.  A single Brahma 12 get's loud enough for most people.  For the price, I don't know if the small jump in output would be worth it. 

And as for which sub, the one's mentioned so far are nice.  But I think you had the best choice from the beginning.  The Brahma's use our XBL^2 motor which has less distortion at any output level than the others.  This means they have the best SQ.
