This is a KICKER X3i 3-way active Electronic crossover a great addition to your car stereo system with a sub volume control long enough to go from the trunk to the dashboard to help control those sub's when you want people to hear them. I used it in my car for about 6 months then placed in storage for the last year just tested it last week and work as good as the day I bought it.
