    That sounds like the line you tapped off of has some compression circuit or something.

    If there was a schematic diagram for the speakers and crossovers I might be able to figure out a good place to try hooking in your line level converter but I don't know what is in there.

    Yeah, the signal is equalized, possibly with a compression circuit before the amplifier that drives the speaker wires you are tapping off of.

    Subwoofers usually use a straight line level out and the sub amp has its own equalization to damp the resonant peak and occasionally to correct for cabin gain.

    What you need is to find a signal with as little done to it as possible (at least in the frequency range you need). Try tapping off a small midrange speaker or tweeter.

    UPDATE: finally installed my radio un my ST today .. right now i had to remove the top display and the bracket that holds it because the metra kit will not fit with the bracket that holds the screen .. i'm now looking for a bracket that will fit and a new screen cover also because the stock one matches with the radio differently for the sony unit vs stock radio .. will post some pics!

    I know this comment is way late to the party, but yeah, your geek's translator is faulty. Ohms are a measurement of resistance across the line, as such resistance is based on the dimensions and type of wiring. Wattage is the measurement of ability to drive a speaker. As such, you wouldn't want to "push" wattage to the bazooka anyway, as it has an inline amplifier.

    You need a line-level feed (A-la RCA, or 3.5mm).
