Ive decided i could part with the system in my Denali
...its a JL 12W7 in the JL box and the amp is the JL 800w mono amp(i think 800, ill check friday night).
Hits nice and hard. less than a year old, and i only drove the vehicle really during the winter.
The sub retails for almost 900, and the amp for almost 400
i'm asking 800 for the pair, and i'll include the wiring.
