I just had the xs12 ported w/ the new jl marine sub amp installed and it sounds amazing. the install guys even said it was the best marine sub they have ever heard. they also did a killer job installing the 420 under the factory remote along with red led's hooked to the courtesy button(took bulbs out of oem lights) and i am so happy with the install and wetsounds i can hardly express it enough. thanks to wet sounds and ultimate audio of orlando. i'll take some pics later tonight/tomorrow.
