I have one Alpine type R sub, 12', with bassworx box, kenwood 1000w amp, and Rockford Fostgate 4 gauge wiring kit. Everything works and sounds great, just dont need it anymore since im selling my car. I paid around 800 bucks with tax for all this stuff brand new, its been in my car for about 3 or 4 months. im asking 525 obo for everything since i need funds for the new car. the box n sub alone are worth almost 500 bucks.
