mountings that ﬁt your preference.
NOTE: If you are having problems after installation follow the Trouble-
shooting procedures below.
Check Ampliﬁer for proper connections. Verify that POWER light
is on. If POWER light is on skip to Step 3, if not continue.
1. Check in-line fuse on battery positive cable. Replace if necessary.
2. Check fuse(s) on ampliﬁer. Replace if necessary.
3. Verify that Ground connection is connected to clean metal on the
vehicle’s chassis. Repair/replace if necessary.
4. Verify there is 9 to 14.4 Volts present at the positive battery and
remote turn-on cable. Verify quality connections for both cables at
ampliﬁer, stereo, and battery/fuseholder. Repair/replace if necessary.
Protect light is on.
1. If the Protect light is on, this is a sign of a possible short in the
speaker connections. Check for proper speaker connections and use
a volt/ohm meter to check for possible shorts in the speaker wiring.
Too low of a speaker impedance may also cause Protect to light.
Check Ampliﬁer for audio output.
1. Verify good RCA input connections at stereo and ampliﬁer. Check
entire length of cables for kinks, splices, etc. Test RCA inputs for AC
volts with stereo on. Repair/replace if necessary.
2. Disconnect RCA input from ampliﬁer. Connect RCA input from test
stereo directly to ampliﬁer input.
Check Ampliﬁer if you experience Turn-on Pop.
1. Disconnect input signal to ampliﬁer and turn ampliﬁer on and off.
2. If the noise is eliminated, connect the REMOTE lead of ampliﬁer to
source unit with a delay turn-on module.
1. Use a different 12 Volt source for REMOTE lead of ampliﬁer.
Check Ampliﬁer if you experience excess Engine Noise.
1. Route all signal carrying wires (RCA, Speaker cables) away from
power and ground wires.
1. Bypass any and all electrical components between the stereo and the
ampliﬁer(s). Connect stereo directly to input of ampliﬁer. If noise goes
away the unit being bypassed is the cause of the noise.
1. Remove existing ground wires for all electrical components. Reground
wires to different locations. Verify that grounding location is clean,
shiny metal free of paint, rust etc.
1. Add secondary ground cable from negative battery terminal to the
chassis metal or engine block of vehicle.
1. Have alternator and battery load tested by your mechanic. Verify good
working order of vehicle electrical system including distributor, spark
plugs, spark plug wires, voltage regulator etc.
