Amp Wont Stay On

[marco_wezo]

I have a Clarion APA200, I just took my car out of storgae and when I went to play my stereo the amp didn't come on. I checked all the voltages at the amp and noticed that I had 12.7 when the amp was off and when I turned it on it dropped down to 7.4. I was wondering if anybody has experienced this problem and if the had a cure. I'm also running a 1 Farad stiffening cap and the voltages are good there also. I ran the amp in the house and it worked fine?

Let the car run for a while or hook it up to a charger it could just be that the battery is weak from sitting and needs to be charged.

Battery or ALT.

I put a brand new 120 amp alternater in last fall and I just put a 1000 cranking amp Optima battery in. I let the car run and the voltage wire slowly went back up to 12V them when I put the trigger wire on it went back down to 7V. I looked at the cd player and there is nothing wrong with it so I'm confused? I think that it might be the tranformer in the amp because I had to boost the car when I picked it up. Anymore suggestions?

you might have a short somewhere, making the amp draw too much current and then killing your voltage. check everything between the amp's outputs and whatever you are driving with it, especially at the terminals on the devices connected to it, just to make sure nothing is laying across them or anything that could cause a short.
if there is no short, your amp might be broken. what kind of amp are you using and what are you powering with it?

Yesterday I replaced all the power,ground and trigger and it still did the same thing, I relocated the amp from its rack just to make sure and it still did the same thing? Anymore suggestions

the power, ground & remote aren't what you should be checking, you should be checking the speaker wires themselves. that is where the problem could be. if there is no apparent short in the speaker wires, then the amp broke sometime while it was in storage (maybe got condensation on the inside that wrecked some components).

I checked the wiring for the subs and they were fine, but that will cause the amp power to pulsate. I think the transformer is gone.

probably ya, take it into a shop to get it tested or fixed.
