    Alright here's my plan...



    Remove ANL fuse at battery.

    Hookup all wires, RCA's last.

    Unplug 350.2 RCA's.

    Set crossover frequency of all amps to 80 Hz.

    Turn on 400.1 subsonic filters.

    Turn 350.2 crossover to "hi."

    Replace ANL fuse at battery.

    Turn on stereo and set headunit EQ to flat and bass to 0.

    Put in test tone CD.

    Put volume to 2/3.

    Play sine wave.

    Set gain of first 400.1.

    Measure voltage.

    Set gain of second 400.1, matching voltage.

    Set bass boost of first 400.1.

    Measure voltage.

    Set bass boost of second 400.1, matching voltage.

    Remove CD and turn off stereo.

    Remove ANL fuse at battery.

    Plug in 350.2 RCA's.

    Replace ANL fuse at battery.

    Turn on stereo and play music.

    Set gain of 350.2.

    Adjust switch on crossovers (-3, 0, +3) to what sounds best.

    are you done yet? lol don't forget your deck has a low pass crossover built in to the sub output that you can control, so i would leave the sub filters on the amps off and adjust from your deck after. If they are both on it's not a good thing and you will gain nothing. That guy on the lowrider site knows nothing about installing...I have 4 volt preouts and i have never had to keep my gains all the way down, that's just plain retarded lol. And i have used many...amps off of this deck.

    I've never heard this before. How do I control that?

    Through the deck, you have low pass crossover in the sub settings, mine, i can set it at 50hz, 80hz, 125hz and there is also + or - 6db gain that you can set from -6db up to +6db gain on whichever crossover frequency you choose, it's like bass boost on your amp. You probably won't need the bass boost on your amps either but you can figure that out when you have it up and running. It's no big deal, just wanted you to be aware that you have two sets of crossovers for the subs, one in the deck and one in each amp, so use one or the other.

    Oooooh, so put the deck on 80 Hz, and put the 400.1's on 0 Hz? or all the amps on 0 Hz?

    yes! or in reverse, but i like to have control up front.

    Okay, set all amps at 0 Hz. And set the crossover on the 350.2 to "off". And I should turn off the subsonic filters on the subwoofer amps... are you sure about that?

    if you are using the lowpass on the head unit...leave the crossover settings on the amps ALL THE WAY UP

    Sweet guys. All the way down or all the way up?

    highest frequency setting

    Okay turn all the amps to the highest frequency setting, set the 350.2 on "hi" crossover, set the headunit to 80 Hz... correct? Azn what about the subsonic filters and bass boost?

    Can I add my three cents worth. This is more of a personal preference thing. I like having some control from my radio, but I don't want the roll off to be too steep.

    Here is how I have mine set, the radio is set to 80 Hz and the amp is set to 120 Hz. It makes sense to me to start the roll off normal and then roll it off steep. I would play with it until you get it right.

    But in any case I have always found that setting the radio lower works best.

    I wonder if we can get The Vikings Opinion on this.

    This is gonna be impressive. I really like it.

    I am so glad you are doing this online. Maybe it will inspire others to do things for themselves.

    Well, here is my 2 cents on the x-over thing....



    If you have a x-over built into you HU, use it....

    The x-overs on the amps are basically the same thing as what your radio has.

    The radio will give you more up front control. Which is good if you know how to use it.

    The amps should be set to full range, or x-over off, then use the radio too set your x-over points. If they sound isnt right, or the upper bass/midbass is too "boomy", then turn on the x-over on the amp, start at a high stteing around 200Hz or so.

    Critical listening is key.

    Every car is different.....

    I like the control up front alot of times, but then I think to myself....why am I changing things when they are right?????

    Just set your radio to about 80 Hz low pass for your subs and about 120Hz high pass for the highs and go from there.....changes in phasing between the highs and the lows can make a HUGE difference in quality of sound.

    If the midbass is too boomy, try raising the highs up a bit. or inverting phase to the mid woofers.....or even going from a 12 to a 18 dB/octave x-over......then invert phase again!!! See what sound=s the best!



    This is something that can only be achieved by a trained or educated ear that knows what to listen for if one does not have an RTA...

    One additional note however.....

    Setting the radio at 80 Hz low pass and the sub amp at about the same will yeild a VERY sharp drop off.....good in some situations, but not most

    As for the subsonic filter, well, most muscic recorded this day and age does not have anything below 20Hz....

    So wehter it is off or on, really dont matter. The subsonic filter was more from the time of turntables, (yall remember them? )


    It aint a BAD thing for a subsonic filter to be on, just probably not needed in most of todays music.

    BTW, good job on the amp rack easy!!!

    Okay just to clarify, does full range mean all the way up?

    Is this correct Viking?

    HEADUNIT:
    crossover setting subs: 80hz
    crossover setting mids/highs: 120hz

    SUB AMPS:
    crossover setting: 200hz (all the way up)
    subsonic filters: on/off, doesn't matter

    MIDS/HIGHS AMP:
    crossover setting: 200hz (all the way up)
    crossover: "off"

    The 400.1 sub amps don't have a switch to turn the crossovers to "hi", "lo", or "off" like the 350.2



    P.S. maybe this thread should be renamed... it's like an extension of my other massive thread lol
