Amp Troubleshooting
POWER
STEP 1
A: Check for 12v at amp using the amps ground, if correct move to step 1-B
If not 12v,check again using a good ground
If still no power, check fuse on both sides of the batt.
B: Check for 12v Remote power using amps ground, if correct move to step 1-C
If not 12v, check remote power behind deck.
If still no power connect to a accessory power source.
C: Check amps ground, If amps ground is good,and it wont power on, Amp is bad.
SIGNAL
STEP 2
A: Check Rca's output at the amp for AC voltage (0.5v-8v) and should change
w/ volume, If correct move to step 3-A
If there is no voltage move to step 2-B
B: Check for AC voltage at head unit (0.5v-8v) and should change w/ volume
If correct, Rca's are bad and need to be replaced
If there is no voltage at head unit, deck is bad and needs to be replaced
OUTPUT
STEP 3
A: Check the positive and negitave terminals at amp for AC voltage should
range from (5v-40v) and change w/ volume.
If there is power, check speakers for correct ohms
If speakers are correct then the amp is bad and needs to be replaced
thanx to BazzGazm for writing this, I only cleaned it up a bit and wanted to share w/ the12volt
