    Line Drivers, USB Dacs, Equalizers, Crossovers, Processors galore!

    Ok heres the thing. I'm working on a carputer setup and plan to not have an HU as my dash wont fit one when I'm done. (I might end up putting one hidden in the armrest console....)

    Anyways. The problem with carputer setups is the low voltage output from most soundcards. Now my initial plan was to use a Creative X-Fi music soundcard. I dont know it's voltage out but most soundcards do UNDER 1volt.

    Now the common thing for people to do is use a external USB soundcard with a higher voltage. Or use some sort of processing to boost the voltage.

    Any ideas Which Way I should go? I'm not sure which to really get.

    Line Driver, Pre-Amp, Crossover, EQ. ? Or should I be looking more towards the more expensive full DSP solutions.


    There are several EQ/Crossovers Which act as line drivers and boost voltages. The one I'm looking at is a Clarion EQS746. It's fairly cheap and nets me the benefit of having a EQ.

    Another is a Soundstream Tube pre-amp.

    Would be interesting to try

    I'm trying to go for great SQ/SQL. Any ideas?

    the zapco dsp will do it all. it is just plain ******. check it out. if it is in your price range, go for it. and since you have a carputer, you can use the program with it.

    carputer and SQ do NOT go hand-in-hand. Unless you aren't going to play mp3 files, you'll just be putting lipstick on a pig.

    All my music is in Flac/Ape lossless audio.

    And how can you say they dont go hand in hand, with the list of audiophile hardware packages out there.

    Then I should say most of the carputer installs I've seen use shuttles with crappy sound cards and they play 192 mp3s. <==lipstick on a pig.

    'hey i've got a carputer, I can keep ALL my mp3's on here' is what I hear.
    It sounds like you are way past that, G/L.

    i have heard the dsp on c2k's in a few installs, and i have the same processing in my reference dc's. it is absolutly awesome. there arent many reviews on it since it is still relatively new to the market.

    i dont know if this would work in anyway.

    but most external soundcards have optical output.

    cant u run that to some sort of processor or maybe amp input?

    wouldn't that give you a great signal to start with?

    already have my amps so I dont wanna change them out.

    Any type of processor input is an option. I'd like a discrete subwoofer channel input. Optical would be great. Just gotta find a solution for sub $200

    Re: Line Drivers, USB Dacs, Equalizers, Crossovers, Processors galore!

    I had same kind of problem you having, I couldn't decide on soundcard/DAC for my SQ Carputer setup. So I had to read over 1000 posts on mp3car.com forum before I made my mind. I can share with you some thing I learned about the "SQ and the Carputer":

    1. Power Suply matters a lot. If you are plannig to use a power inverter, forget about the SQ. It'll make a constant system noise no matter how well u ground it. (proven )
    Use only DC-DC PSUs. Opus-250 most powerful PSU available http://www.digitalww.com/opus250.htm plus it got automatic shutdown/sleep option.

    2. Forget about the RCAs, think Optical. All soundcards I know don't produce more than 1-2 volts output and that includes Audigy X-FI and M-AUDIO Audiophile. Auzentech X-Meridian is the only one exception with 4v preouts but its not out yet.
    Just use any card equipped with toslink style optical out.

    3. External DSP/DAC with Optical Input.
    Zapco DSP6-SL is #1 but pricy. The best price/quality DSP/DAC is Alpine PXA-H700/H701. It will convert your optical signal to 4v analog, also got: 165 Band Graphic EQ, 27 Band Parametric EQ, Dolby PRO LOGIC II, Time Correction, etc
