    Default is this a good setup???

    well right now i have

    alpine cda7863 head unit
    polk mm465's up front
    polk 5.25 db's in rear
    subs are 2 mm110's

    should my amps be bigger?????

    i currently have alpine t757 for subs
    and alpine f407 for rest.. the 407 dosent seem to be enought for my mids and tweets

    i have the f407 bridged on the mm465's and is that enough

    i also plan on getting the new alpine cda 7977 with 4v outs

    would that bump me up more

    any suggest,,,,,,, and i can buy a diff. amp if you fill nessasary
    but def want to stick with alpine

    thanks jaron

    Try bridging the amplifier and connect the MM465's to the amp.
    In the bridged mode this amp has a power rating of 320 Watts
    per channel. Set the high pass crossover to 80 Hertz and do the same for the low pass filter. Because the amplifiers use a 12 dB per octave slope, you may have to invert the phase on either the subs, or the component speakers and back speakers to get the system in phase acoustically at your listening position inside the vehicle.

    If you have any questions feel free to give us a call
    at 800-377-7655 between the hoursof 9 AM to 6 PM Eastern time and we will be glad to help.
