Scosche's LOC80 line output converter allows you to connect a receiver with no preamp outputs to an amplifier without speaker-level inputs. The LOC80 handles a speaker-level signal up to 80 watts RMS per channel, and converts it to a line-level signal you can plug into your amp's input.
The LOC80 reduces the incoming speaker-level signals so you can use a stereo RCA patch cable (not included) to make the connection to your amp. The converter features adjustable gain settings on each channel, and it's compatible with almost any car stereo. Warranty: 90 days.
