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
