    output is in AC. you can measure it by playing test tones. it should read a different voltage for every frequency. thats how you get companies like clarion posting amplifeirs that can do 1000 watts, when they measure output at 1000 Hz, where its easy to post high numbers, versus high end amplifiers that may be rated at lower or multiple frequencies, that present a more realistic power value.

    regardless, check out the price on the overdrive. its a two channel line driver, I might consider jsut driving the front channels, not the rear. you can always get a second one, if the price of two is less than teh cost of one matrix.

    your second option is to check out some of david navone's products, he makes hte best electronics in his field of production that I personally know of. cant go wrong with navone! I believe the site is www.davidnavone.com, if not, google it, itll be something like that. im pretty sure he has a four channel line driver.

    good luck!

Most songs I can compensate for the bass using cut off frequencies and what not. I was wondering if a preamp after my audigy but before my stock amplifier would yield louder music. Oh by the way I have a stock BOSE system.
    Ah, the WONDERFULL bose sound system...

    What you are looking for to fix this is a devie that will convert your UN-Balanced output from your Audigy to a Balnaced output. Ths Bose amplified systems in cars (that I worked with at least) required a balanced signal input. If you are unfamiliar with balanced audio, here goes: A balanced signal looks like a regular unbalanced signal, but the negative lead (usually the sheild) has the identical signal on it, 180 degrees out of phase. The signals on the negative and positive leads look like mirror images of each other. This is done to eliminate noise getting in the system as the signal travels from the source to the amplifier.

    A line driver might not help you out, unless it has a balanced output, but this is a bit uncommon.

    Check with some of your local GOOD car audio stores. Tell them you want to take a "preamp signal" and send it into your Bose amplified system, and that you know you need a "BALANCED" signal into it.

    Should make all the difference in the world on yours.

    Don't forget that a lot Bose speakers in cars are 2 ohms (some even 1 ohm). Bose did this to effectively leverage the 12 volt power system and build more powerful amplifiers (36 watts to a 4 ohm speaker, versus 72 wtts for a 2 ohm, if the amp can handle it).

    Most amplifiers are only stable with regular car stereo speakers (usually 4 ohms). If you buy an amp, you may want to see one of your better local car stereo shops prior to purchase and tell them your situation. Most "mom-and-pop" shops would be VERY willing to help you out with info/recommendations. I know if you walked into the shop I used to work at, telling me what you were doing, I would (as well as everyone else I worked with) jump at the chance to help out and see it.

    So I get what Your saying. Would something like this http://www.davidnavone.com/detail.asp?PRODUCT_ID=N-684V
    work for me then?

    EDIT: I just looked up specifications for the audigy 2 nx and it says that it outputs 2volts rms. I read almost a volt in my car when attempting to measure it. DOn't knwo where the other volt went.

    Did even more on turning an unbalanced signal into a balanced signal. I found a wealth of information which only lead to more questions/problems . Now I saw this product http://www.whirlwindusa.com/pcdi.html
    Now that will turn unbalaced into balanced signals. SO yeah I found a way to do it. BOOOO it uses XLR outputs. I did some more researching on XLR connections. So in a nutshell what I got from it is that 2 of the leads are basically powered. allowing the output voltage to be doubled. Now here lies another one of my problems. Since I can hook my audigy up to that product and get myself From unbalanced to balanced. Connect the LIVE output from that "box" to the positive speaker lead that heads to my bose, and connect the Reference andd Ground to the negative speaker wire heading to my bose. This is what I am interpreting from my google searchs and such. Please tell me if I'm totally nuts and just made that stuff up or if it is somewhat true. Thanks for everyone's help so far!

    the audiocontrol overdrive puts out a balenced signal, by flipping a jumper inside teh unit.

    Just got my e-mail back from Audiocontrol regarding the whole balanced unbalanced issue. This is what they said

    "The Matrix will balance the signal at input allowing it to reduce/reject noise. It's output will be unbalanced, but the balanced inputs will reject noise at that point in the signal path.

    At 03:15 PM 7/6/04, you wrote:


    The matrix line driver says it supports balanced audio signals. Now if my source going to the matrix is unbalanced and the matrix is in balanced mode, will the matrix's output be balanced? Thanks for your time."

    SO this leads me right back to square one with a unbalanced signal(but more powerful one) going to my bose if I use the Matrix/Overdrive.

    DAMN YOU BOSE! DAMN YOU!

    dang, i guess I was wrong. wel, the overdrive supports balenced inputs too, i guess!

    Seems that almost EVERYONE uses a differant sound output device than what exists on their mobo. I'm planning on doing it myself just because I want the best SQ possible, even if that means sacrificing SPL and or my next months mortgage
    Has anyone had a GOOD experience with the onboard sound from the mini-itx boards? UPS still has all my equipment so I haven't had a chance to test it out for myself.

    onboard= no no for good sound. Also it was easier to run a usb cable thats in my glove box to my center dash hub that it would be for me to run 4 cables from my trunk to my center dash. If you want good quality sound then replace everything audio wise in your car.
