Premier hazard amplifier and rvl 100 watt speaker I had this installed for the bull horn however other functions are still active and not that hard to figure out ;) powder coat has peeled on the speaker but does not affect its ability to scare the living **** out of unsuspecting friends Postage is high at the speaker is not light!!! And the cables that are cut short on the amp in the green plug are screw driver release so easy to add new cable Due to working away I may only be able to post on weekends
