    OK great value very poor packing, item hurt by shipping company, first 4 contacts in first four days I got four different answers to supply of one lost tee piece after providing pictures and fixing the bent parts. Finally seller advised they had no control of inventory of small parts that come in their items, and I would have to repack and ship back a 50 lb item and receive a refund then I could repurchase. I modified it and made the item work for me. I think I would buy elsewhere but item is A+

    A+++ First order I received was damaged in transit. I contacted the seller and their customer service was incredible. They immediately took full responsibility and offered a refund. My second order came with extra protection in packaging and the subwoofers work perfectly! I am very satisfied with my purchase!

  • Top critical review

    Terrible sound, difficult to install.

    must remove entire interior. lots of little clips to break. door speakers do not fit well. you must modify the adapter bracket significantly to make it work. Speakers can not handle the power of the amp bridged or running a single channel. you must hook up all 4 channels, so you need a head unit with 3 pre-outs(sub channel included. even running all 4 channels on amp, volume can not exceed 3/4 volume or speakers will cut out and/or distort. Very bad components not worth the money.

  • Not factory replacement

    I am returning this item because it is not a factory replacement. It would take a considerable amount of cutting and fabrication for these speakers to work in a 1991 bmw 850i

    Not exactly right fit no instructions plugs were different cheap RCA cable all in all though great sound looks good now instructions and not correct. Size made insulation a little more difficult.
