    Really need help picking an 18" sub

    I have been all over the place the past few days trying to figure out what I need. So here is what I have to work with...

    2002 Infiniti I35, it has a decent sized trunk (same as 00-04 maxima), folding rear seats, and it rattles like hell


    * Mechman 270 amp alternator
    *big three done with 2/0 welding cable
    *run of 2/0 welding cable to rear battery
    *Diehard advanced gold agm (775 CCA, 55AH) front
    *Diehard platinum agm (930 CCA, 75 AH) -rear

    Box Specs

    *can fit up to 8 maybe 9 cubes
    * plan on tuning to around 26-28 hz via a 8" aero
    *using birch ply for majority of the box with double mdf baffles
    *bed liner outside, enamel paint inside

    I want good sounding low bass, but enough cabin pressure to do a few bass tricks. my budget for a woofer caps at 620 bucks, but I would like to spend alot less

    Subs I am currently considering Include

    * FI Audio SP4 18" w/upgrades
    *Sundown Audio Zv4 18"
    *SQ HCD4

    I am also unsure how much power i want to throw at whatever I get, recommendations on amps are also welcome, just note my overall budget caps at 1'100 tops

    and I applogoize for this being so similar to my last thread, i'm just trying to narrow down my choices

    Ride: 2002 Infiniti I35
    HU: Pioneer PRS-80 w/ a JL Audio Linedriver
    Front Stage: Infinity ,Infinity KAPPA 6.09cs (front doors, rears need replacement)
    Sub Stage: Sundown Audio Z.V4 18"
    Front Amp: Soundqubed 120.4
    Sub Amp: Soundqubed 2200.1
    Power: Mechman 270A alt, Diehard advanced gold agm (775 CCA, 55ah) XS Power D3100, and something like 40' of stinger pro series zero gauge throughout

    HDC4 18 and 3500.1 would come in under budget during the black friday sale, but I wouldn't tune an HDC4 that low personally....
