    Default makes ported and sealed boxes makes sealed boxes.

    Both of these companies use 3/4" MDF instead of 5/8" thick MDF. Made very well.

    If you want some serious sound and want to be original, then I am selling my 4 Sundown Audio SA-8 V.2 Stock SPL 8" subwoofers in a custom ported fiberglassed box at 3cu ft tuned to 31Hz. This will only fit NNBS 2007+ Crew Cabs with a 3" seat lift, which I have a kit for it. I totaled my Sierra in late August before I got to install the subwoofers and amps in the truck. I was in the middle of redoing my wiring. I went to the tow yard and pulled out all of my stereo equipment and my T6-6061 Aluminum rectangle .25" thick blocks for the seat lift. It worked great! I uninstalled the blocks after installing them with the seats to make sure they fit well and they did. When I had the accident, the blocks were sitting in my bedroom about to be installed the next day.

    It's up to you on how much boom you want. These are by far the absolute best 8" subwoofers out on the market. You can do some research on them on and People rave about these subs. Rated for 600wrms, but I was going to throw 900wrms at them and Jacob, owner of Sundown Audio, told me that these subs were the Stock SPL versions and could take 1000wrms.

    Not a problem. To get quick responses, then I suggest posting in the Subwoofer/Enclosures thread instead of the For Sales section.
