    Performance Teknique ICBM-7788CD

    I can't find a single thing about it anywhere on the whole internet. It cost me $110+tax installed. It has CD Changer controls but the guy didn't hook them up to my Acura CD changer. Are all cd changers universal or usually not?

    Also do these features sound good, I'm typing them right off of the box.

    Active black matrix
    Rotary Encoder switch
    Loudness control
    Sub-woofer control
    5 volt pre-amp output ---(that's good right?)
    pre-amp rca line out X2
    Subwoofer line out X2
    Left & Right level meter
    Remote Control
    AM/FM/MPX Stereo
    Built-in Noise filter
    1 Bit d/a converter --- (typo? cuz it says 16 bit in the manual)

    In the manual here's what it says under specifications.

    Signal/Noise Ratio - >80 dB ---(is that necessarily bad? i know it could be better)
    Frequency Response - 20 Hz~20KHz
    Channel Seperation - >62 dB
    D/A Converter - 16 Bit ---(says 1 Bit on the box)

    The type of D/A converter (dac) does not matter as long as it does the job correctly. A 1bit dac will sound the same as a 16bit one if it's doing its job correctly (and these days almost every dac does a perfect job)

    A 5v preamp output is plenty high, assuming its true.

    Signal to noise ratio does not matter in a car because its already high enough to have no problems unless you use very high efficiency speakers. Even then, when you factor road noise, engine noise and other factors, it makes even less difference. Manufacturers rate differently too, so it's hard to compare values.

    The Frequency response for most solid state electronics is fine, almost any unit these days can be audibly flat across the audible spectrum. Again, this spec doesnt matter much either. :hs:

    The channel seperation of 62 dB should be plenty high. Even if it was as low as 40dB or something, you probably wouldnt hear the difference.

    all i know is so far it sounds good in my acura legend

    HU goes to a 800W 5Channel kenwood amp, which goes out to Infinity reference speakers and a Alpine TypeS 12" sub.

    the only reason i had to get the HU was because when i transferred my amp/speakers from my other car to this car it was picking up MAJOR engine noise

    the only thing i've seen was their amps in the trade mags so far, and they look like flea market grade stuff. next year they might be called audio teknique, or something to that effect. :dunno:
