12 inch JL Sub Woofer, Q Logic Box, MTX Amp - $125 (Grand forks)
JL Sub that sounds great in a charcoal colored custom under seat box designed to sit under the back seat of a pickup. Charcoal in color. Powered by an MTX Blue Thunder Amp that's matched to power the sub perfectly. I bought these items new from Best Buy 5 tears ago for over $650. Sounds great and really wakes up a stereo system but my new vehicle has a stock sub so I no longer need this one.
