Specification Brand : Alpine BulletPoint1 : 4 Channel Add an Amp Adapter. Use this adapter to make your installation of a 4 channel amplifier to the factory system faster with a cleaner install. Use this plug and play adapter so you don't have to cut or splice into the factory wiring. Provides 2 pair stereo RCA output. Adjustable 4 channel gain output. Retains fader and balance. BulletPoint2 : Use to add a 2/4/5/6 channel amp to power the vehicle speakers. Connection is done at back of radio. Quick disconnect bare wire connector to connect factory speakers to the new amp- won't require looking for or cutting of factory speaker wires. The speaker wire is already cut on this adapter so you can connect speaker wires to it to run to the new amp- once this adapter is connected the factory speakers will need to be connected to an aftermarket amplifier for the system to work. BulletPoint3 : Quick disconnect is to connect speaker wires to run to the new amp- only the speaker wires are connected to the factory speakers- all other wires aren't used. This adapter doesn't have the amp turn on wire- that has to be found and connected separately. Connecting this adapter to the factory wiring will disconnect the vehicle speakers from the radio- required adding amp for speakers to work.
