Would probably have to be run off an inverter which would need the power to be smoothed out a little bit first to get its full potential but would blow everything out of the water without going into the absolutely ridulous price range. If you want an eq as well a high quality eq could be paired with it.
    the shear fact that you would have to run it off of an inverter alone would mean that it WOULD NOT blow everything out of the water. Inverters introduce so much noise (not only system noise but fan noise) isn't not even funny. Inverters do NOT belong in SQ cars, period.

    With that being said however, the DBX Drive rack is a viable solution (something I'm actually considering heavily in my next install). (http://www.dbxpro.com/)

    there are waysto use home/studio audio equiptment in a car without using an inverter.... this has been done for years...., I think dave navone or richard clark were the first I seen do it....

    basically, even though theequiptment is plugged into 110vac, doesn't mean it actually runs on 110v ac.... the transformer(power supply) in the unit takes the 110 ac & converts it to what the equiptment actually runs at....

    now if a rane eq runs at say 24v dc then you would need to build a pwer supply to meet it's needs.... going from 12v dc-110v ac- 24v dc doesn't make sense, but going for 12vdc to 24v dc is a viable option....

    this is normally how it's done on a pro level.... no 110 ac inverters.....

    just a heads up, this is a response i recently got from a manufacturer of some rack equipment. I was exploring the option of using rack equipment to retain a balanced path from my soundcard to a x-over, then to the amps



    Hi Scott and thanks for writing to us! Because this model uses an international 'switching' power supply that could prove quite complicated, as there are several different 'taps' off of the power supply for different voltages and separate ground connections for the 'digital' and 'analog' circuits of the device - so it might actually be easier just to go the 'power inverter' route on this one, particularly since you need +15 and -15 legs in addition to the others. You would need to provide the following voltages:

    5v
    3.3v
    +5vd (the 'D' or 'A' stands for 'digital' or 'analog')
    DGND (digital ground)
    +3.3vd
    +15va
    AGND (analog ground)
    -15va
    +9va
    5v
    So, make sure that it's doable before you purchase the equipment

    that's very doable if you were intent on using that equiptment in your vehicle....,2 carnetix & a standalone or two should do it I would think...A few hundred bucks & it should be as efficient as if it was made for the car.... . but there may be other equiptment that would be easier to use of course... & in this case the cost and/or space may be prohibitive...

    of course you'd have to also know the amperage draw of each rail...


    I didn't even realize that the latest equiptment was using such complicated differing levels of power... but I guess there a computer of sorts in there own way too now adays...

    a lot of soldering too :-)

    maybe you can answer this...what the hell is a digital ground?

    don't take the following as gospel, as I am not 100% sure of the following, but this is how I think it works:

    I'm pretty sure this means that the internal components are seperated on two different groung planes to eliminate cross interference.. basically like two seperate components, each with there own seperate power supply, even though the whole package may be wrapped into one large powersupply it really amounts to the equivelent of several....


    the digital ground is the ground from power supply "A" for example & the analog ground is provided by power supply "B".... it is a "digital ground" only because it is the ground that's used on the digital side....

    this is why I said 2 carnetix... looking at it further I think the 15v is only required on one side, you would need to confirm these facts if you indeed intended on persuing this further, as well as confirm amperage draw of each rail, but I think this isn't that hard to do really...

    That's also what I understood...

    thanks, i've since changed my mode and wont go that route. i was more or less just curious to what it meant. thanks for the explanation.

    There are ways to modify the Drive Rack to run off of DC. It's about $400.
