My dad has a JL Audio stealth box with a JL 10W3. It's maybe 5 years old. Anyways the amp died and I need to find him a new one. I have no idea if the sub is DVC, SVC, 2 ohm, dual 4, whatever. Without unistalling the stealthbox, is there anyway I can know what impedance it's running at? I suppose I could look up the model of the amplifier and find it that way, right? BTW, stealth boxes are pretty sweet.
