    Passive or Active crossovers for my install tommorow

    I have a 98 Nissan Maxima gxe model. Its time to replace the stock components. The tweeter is located on the door panel close to the apiller and the mid is in the typical location on the door.

    I have a CDT HD62 set with the passive crossovers and DRT 26sat tweeter set.

    I have a 5 channel RF Power 1000 amp that does :

    Rated Power Front/Rear Channels
    50 W x 4 @ 4 Ohms RMS
    100 W x 4 @ 2 Ohms RMS
    150 W x 4 @ 1 Ohm RMS
    200 x 2 W @ 4 Ohms Bridged Mono
    300 x 2 W @ 2 Ohms Bridged Mono
    Sub Channel
    300 W x 1 @ 4 Ohms RMS
    600 W x 1 @ 2 Ohms RMS
    800 W x 1 @ 1 Ohms

    Total Power 1400 Watts
    Bridgeable Yes (front/rear)
    Crossover Controls Front Channels
    High-Pass (HP): 40-400Hz 12db or 24db/Octave Linkwitz-Riley
    Low-Pass (LP): 40-400Hz 12db or 24db/Octave Linkwitz-Riley
    10x crossover switch
    Rear Channels
    High-Pass (HP): 40-400Hz 12db or 24db/Octave Linkwitz-Riley
    Low-Pass (LP): 40-400Hz 12db or 24db/Octave Linkwitz-Riley
    10x crossover switch

    Sub Channel
    Low-Pass (LP): 32-250Hz 24db/Octave Linkwitz-Riley
    Infrasonic filter: 28Hz fixed

    more info there : http://www.rockfordfosgate.com/produ...5&locale=en_US

    I was told that if i mount the tweeter farther from the mid to go active and if i mount the tweeter close to the mid to go passive and put 200 x 2 @ 4 ohm to it.

    Any recommendations are appreciated. Thanks

    What HU/Processors do you have...that determines if you can go active.

    Sorry, i have a Alpine CDA-9813 and it offers 3 way active crossovers. I have always gone passive so this is new to me. I dont mind going passive if my installer can find a place for the tweeter right by the mid.

    There is a lot more than just how far the tweeter is from the mid. The acoustics of the car also plays a very important factor. A decision to go active or passive just on distance from the each other is a poor decision. Infact, distance from the ear is more important than distance from each speaker. Then there is also the angling of the speaker and such that also have to be taken into account.

    I would recommend to hook it up passive first. If then you don't like it, then move to active.

    Sounds like a good idea. Thank You

    I will try and mount the tweeter closer to the mid.
