Line Output Converters
Turn speaker-level signals into RCA outputs for adding an amp
A line output converter taps your factory speaker wires and creates an RCA signal an amplifier can use. It lets you add an amp or subwoofer when your stereo lacks preamp outputs, keeping your original head unit in place.
We curate top-rated line output converter picks on Amazon so you can match channels and features to your system. Check the number of channels you need and whether the unit includes a remote turn-on trigger before buying.
