    Gain on an amplifier to meant to be matched to the output voltage of your headunit. Think 3 volt, 4 volt, 5 volt pre out specs you see on headunit specs. This is how gain works for a given pre out(5 volt) theoretically. However most head units clip(start to distort) at around 80% of your volume so your 5 volt pre out wont give 5 volts Cleanly. You will most likely get 4 volts out at something like 33/40 on your volume knob and would thus set your gain to 4 volts. (these things can be measured with a GOOD Multimeter. )
    80% of your total volume is (max volume) X 0.8.
    Example is 40(is your max volume so, 40 X .8=32

    ^^ive heard his system. hes got two 12s in a sealed box but he also has like 2200 watts going to it. but yea. His 2 tantrics are far louder than my 1 sa-12 ported. but thats to be expected.

    you can go sealed all you want. Just add a few drops of power, maybe gallons, you get the drip.


    however I see a very nice walled off trunk build in the works lol.

    Re: sealed enclosure for 2 SA12-D4'S

    yeah those subs were pretty efficient and played very flat while getting nasty, first time i saw inches of windshield flex and my first mini shirt trick on a corolla.. I never actually fully powered the 12, only had a brx 2400.1 on it. If given the chance(in classifieds for a pair of xcon/zcon 18s for a good price), I'd run them again in a heartbeat.

    And the car isn't hacked up like some might think I'll get some more pics soon I'm on wiring and finish work then put all of it back together 1 more time. Btw you can't see it but befor I cut out the rear dash I welded in a 1" square tube and actually hacked my box instead had to kick that beast in but have you know the seats still latch in the upright position only sheet metal removed was a piece big enough for the port and some tiny slivers the rear dash is welded back in and look great
