Amp wont turn on..Visonik vb212pkw
I installed this visonik amp but when i turn it on the protection light comes on I check the wiring and its ok but when i check the voltage on the amp. terminals it reads only 3V how does it happen it is connected directly to the battery even if the engine is running the voltage is the same

Well you have a high impedance path to your amp. If you have an inline fuse that should have blown. Car batteries don't have a current limiting feature HA The only explanation would be that the amount of current passing through the wire is causing a large voltage drop due to a large impedance. What gauge wire are you using? Here is an example.
18 ft of 8 gauge wire would have to be passing about 400 Amps of DC current to yield a voltage drop of that magnitude. The wire would melt and all hell would break loose. So there has to be a break in your wire somewhere.
