INSTALLATION OPTIONS
Adding a full-range amp and subwoofer to a factory system:
This feature offers the ability to add a full-range amp and sub to a factory system, whether amplified*or non-amplified. (Refer to Page 3)
* For amplified models the amp must be bypassed/unplugged. Refer to www.MetraOnline.com for the vehicle specific amplifier bypass harness.
Note: The interface provides a 12-volt 1-amp output to turn on aftermarket amp(s). If installing multiple amps, an SPDT automotive relay will be required if the amp turn-on current of all amps combined exceeds 1-amp. Use Metra part number E-123 (sold separately) for best results.
