Amp is in protect mode. check your wiring and make sure your sub is wired properly for ohms. dual 4 ohm in parallel = 2ohm. dual 4 in series is 8 ohms. dual 2 ohm parallel= 0.5 ohms and in series 4 ohms. check ground and power wires. make sure sub isnt blown. a blown sub WILL cause this on any amp.

Won't work after re-installing Boston speakers


would try it with the correctly rated fuse as there may not be enough wattage / current to power the bass unit with a thin wire.

Also how long ago was it flooded as it may take quite a while in a warm area to dry off completely ?
