Amp Issues

[DaSmittyman]

Hey everyone,
Alright so the problem i am having is the amp. When ever i turn on the car, the amp turns on then off. After it is off and barely blinks and the subs barely hit. I tried another amp that i had, and it does the same thing. I have a new battery(replaced it today actually old one was only cranking 200 amps i think), I replaced the in line fuse in the engine compartment, still the same issue. I am running 4 gauge power wire to a 1.5 cap, then to the amp. I disconnect the cap and put the amp straight to the batter and the same problem. Is it possible the power wire is bad? I am also about to go replace the Neg so thats still in the air also. Anyone else has any other ideas?

possibly not a good enough ground... did you check that?

[Dozier]

Yup...I would check that ground.

check the voltage at the amp, it may not be turning on due to low voltage.

check the voltage at the amp, it may not be turning on due to low voltage.

Im at school right now, but i will check that too. If it is low voltage what would be causing it.

Poor connection from the battery, or maybe a bad or incorrect connection behind the radio for the amp turn on wire.

bad connection from the battery, bad connection for the grounds.

[DaSmittyman]

its bad connection for the grounds i checked everything else ahah but ya i guess the terminal ended up loosing up on the wire. or i didn't tighten the hex down lol thanks guys
