Test Power Wiring
1.Turn on the receiver but do not turn up the volume. The amplifier power light should come on. If not, check the RMT and +12V wires.
2.Turn up the receiver volume slightly. All speakers should operate. If not, check wiring connections at amplifier and speakers.
Professional Tip
Dealing with Alternator Noise
The vehicle alternator can cause a “siren” sound in the speakers that changes with engine speed. To prevent alternator noise:
•Do not bundle RCA cables with speaker or power wires
•Do not run speaker wires parallel to power wires
•If you have more than one amplifier, connect all ground wires to the same screw
•Make sure all wires are as short as possible
•Make sure the receiver black wire has a good connection to the vehicle chassis ground
Test Speaker Connections
These tests make sure the speakers are connected right. If speakers don’t play at all, one (or both) speaker wires may be discon- nected. If the wrong speaker plays (you hear left speaker when you expect right speaker) make sure you connected the wires correctly.
Once everything is operating correctly, reassemble vehicle trim and dashboard.
