    wait. when a box is loaded into the trunk. and the port is near the trunk wall. it drops the frequency even lower?

    If it has something close enough to load off of it should tune a little lower.

    Re: Fi sounds like its bottoming out only on high notes

    I'm not worried about my tuning changing, im more worried about that popping noise now

    It's not clipping, and i doubt its overdriving the woofer. The BL is rated for 1500 and with box rise im probably never seeing that from the SK-1500.1 Itll pop but play the song back at that exact point and it wont. Sometimes highs sometimes lows (never LOW LOWs though)

    The popping is being caused by my 6x9s being forced upwards. Im all happy now :P

    I was about to pull the sub apart and look at the internals and do free air testing. I just took it to a local shop i just happened to pass by and they immediately isolated the problem to the deck. They recommended sealing off the deck speakers if i choose to keep using them lol
