My amp is not working

I have a visonic amp and i hooked up everything rite but it dosent come on at all the light dosent even come on but i kno everything is hooked up rite because i hooked up my other amp that comes on but on that the light comes on but no sound comes out my subs so i dont know what to do

For the visonik, you should check your speakers. You can use a D-cell battery. Remove the speaker wires from the amp and connect each speaker across the battery (for no longer than a few seconds). The speaker should pop each time the wires are touched to the battery. If they don't, the speaker is defective (assuming the battery isn't dead).



If the speakers are OK, you need to confirm that you have a good signal feeding the amp. You can use the RCA cables from another working amp in the vehicle. Do this with the amp that had the power light lit.



If you have signal going to the amp and the speakers are OK, the only two things left are the power supply feeding the amp (from the battery) and the amp. If you have B+ and remote voltage AND a good ground, the amp is defective.















For the pyramid, the amplifier probably has shorted output transistors. The amplifier will have to be repaired.
