bassasom, Since your boxes are all fiber glassed together, then routing is a challenge. Though you can run wires and tie them up under the lips, then grommet them through the walls. The wire is a colored wire (orange we think? though not sure) from your accessory switch on your dash. You can run from the terminal block on the transom, or the master power switch also. Routing it best figured out once you determine the source of power. BCB
