–17 – T ROUBLESHOOTING This troubleshooting guide is intended to assist you with certain problems which may occur. If you still encounter problems, see your Authorized Rockford Dealer for assistance. Problem Amplifier will not play — Remote Turn-on light is off. Solution 1. Check the DC voltage at the amplifier ’ s B+ terminal with a voltme[...]

Problem Amplifier gets too hot. Solution 1. Be sure the amplifier is properly mounted. You should be able to place your hand a few inches above the amplifier housing and feel the heat rising when the unit is on. Hot air rises. Consequently mount the amplifier with the heatsink fins aligned vertically. This allows the air to flow freely, carrying aw[...]

Problem Engine Noise (Whine) Solution 1. Disconnect the speakers from the amplifier. Connect a test speaker to the amplifier output terminals. If the noise goes away, check your speaker leads, speakers and crossovers. 2. If the noise persists, use a “ shorting plug ” to mute the input signal at the amplifier. If the noise goes away: a. Bypass a[...]
