    kenwood kdc-210u only one set of pre outs need advice

    Hello everyone ive been out of car audio awhile and need help.

    Vehicle 2003 Silverado Crew cab 4 door.

    I was given as a gift a new kenwood 210u that has only one set of pre outs it has the ability to run 85 hz/120hz/160 hz or through also has rev phase (180) or norm (0)

    heres my dilemma i plan to use component 6 1/2s in all 4 doors but currently have 6 1/2 coaxials.
    I am powering these with a Zapco 350.2

    For subs I have 2 12"Directed sx12d4s
    i am powering these with a Directed D1200

    Since theres only one preout i currently have it split via a rca y splitter creating 2.

    oh btw I am NOT using any Line level speaker connections strictly rcas via the 1 (now2 via splitter) preout.

    Are my door speakers getting mutilated by bass frequencies? It seems when I do turn the bass down via the head unit to accomodate the door speakers from getting mutilated the bass gets turned down as well. Seems as whatever i do via the head unit affects both amplifiers.

    How can i tune both amps individually to accomodate both the door speakers and the subs? and still have full functionality of fine tuning from the head unit?

    Someone please help as i have already burn 1 set of doors and cant afford to keep going at this pace. Thanks in advance.

    Are you using the on board crossovers? Or running both amps full range?

    you really dont want to split the signal, might want to sell that head unit and get one with enough sets of preouts if you want optimum sound since you have a multiple amp setup. If anything there's always line drivers for a cheap fix but thats all it is, cheap unless your going audiocontrol then thats the price of a new head unit anyways.

    If someone gives you a brassiere, do you go ahead and wear it even though you're a man? Assuming you're male, that is. ;-)

    First... To clarify, you are using line level outputs. RCA cables carry the line (low) level signal and speaker wires carry the speaker (high) level signal.

    If you don't want to install a head unit that's made for your application, then you have a couple of options. You can leave things as they are and turn up the bass boost on the subwoofer amp so that you can turn the bass down on the head unit and still have reasonable bass output from the subs. Or, you can install a line out converter on the head unit's front speaker outs and run that to your front stage amplifier.

    Neither of those options will allow you much control over the sound quality of the system but the second will at least give you the ability to bias the signal toward the subwoofer in order to enhance your bass response.

    Lastly, if you're burning up speakers there's a pretty good chance that your gain is set too high. What method did you use to set the gain on your amps?
