    Default Help please, PA 880 amp with 1 - 12" DXI 124dvc ???

    So i just got my PA 880 amp installed with a single 12" DXI 124 DVC 4ohm dual voice coil subwoofer. The amp has a bunch of buttons and i don't think my installer messed with any of them but he might have. Can Anyone help me with what settings i should set the knobs and buttons to on the amp? I just want to get good bass from the sub without damaging it. I exhanged one of these subs because the spider wire or w/e near the connection metal tabs on the subwoofer were cracking and coming apart. I have a feeling its from too much heat so i want my amp configuration to match this 1 sub i have. Thanks for your help. Here's some pictures and specs.

    Turn bass boost off. Phase set to 0. Gain set to the 10:00 position. Crossover set to low pass. Set the crossover frequency to the 10:00 position and adjust it as needed for what sounds best to you. You can turn the gain up a little if the sub is too low but don't go above the "noon" position. Its not a volume knob, it matches the amps input with the head units output so that when the head unit is at 50% volume, the amp is too.

    what is the power handling of the sub? if it can handle the power the amp and push out, you should set the gain with a DMM, there are tons of videos, and JL audio has step by step instructions on how to you gains with a DMM.

    this was funny situation. i had done some work for a guy i know. he asked if i wanted his old klf10's in his closet. i said ok. i brought them home. wife said get rid of them. shes not much into the speaker scene. but i had to laugh. im new to polk audio and she doesnt care. so i though. she is my ears when i set up systems. she didnt even want to hear them. she said she liked our sda2's. i thought id share this with polk lovers. i decided my long 3+ years of changing out speakers has come to a end unless i come across some other old polk speakers. i hope to find a good home for these speakers....so i think i will sell them or givr them to someone who may need them..they are like new inside. couple of scratches....now the bad. he put a plantpot on one of them. there is a ring on top. i could sand it down n stain it i guess or just tell whoever to put a cloth top and youd never know. i guess. any ideas what these speakers are valued at today. or should i just sell them with condition there in. i know its hard without pictures. also. i hope im not breaking rules by asking
