DX504-70 Harley-Davidson Applications

Recommended for 4 ohm amplifiers and aftermarket source units only. Stock 1998-Newer Harley-Davidson radios utilize 2 or 8 ohm speaker outputs (excluding some CVO radios). Due to the 4 ohm voice coils in these speakers, they should not be connected directly to the stock radio speaker outputs. Failure to follow this guideline can damage your radio and void your warranty. Not for use in Tour-Pak speaker pods.
