Sub box for 12 subwoofer, had this in my previous car but did not need it anymore since new car had a great sound system already installed. Approx one cubic feet, had a JL sub in it, which is also available. Sub box is $40, obo.
JL sub is model 12w6v3-D4, strapable for2 ohm or 8 ohm, see pics. Handles tons of power, look up the model number online for specs and current pricing, looks like $800 new and $600 used, if interested call me and we can discuss price etc. Located in southwest Petaluma.
