Yes I'm sorry, but I've got another question about an amp not powering up. I just got a brand new Profile CA200 and it won't turn on at all. The protection light doesn't even come on.

Voltage at the battery is 12.4v. Voltage at the amp is 12.4v with car off; so thats fine. Ground is secure and attached to shiny metal with paint sanded off; that should be fine. Remote terminal has about 12V. I've tried using a jumper wire from the power terminal to the remote but still no use. So thats not it. Same thing happens with or without rcas/speakers connected so its not a blown sub or anythng like that. Amp is not mounted yet so its not touching metal or anything.

Similar thing happened to my previous amp (usx-4065) which I just unhooked because I thought it was fried. Only difference was the protection light would come on for a couple seconds then shut off. On both amps, after turning the head unit on, the voltage at the power terminal would drop way down to 1.5ish volts and would gradually climb back up to 12v. So now I'm thinking if a BRAND NEW straight out of the box amp isn't working, maybe my old amp is still fine too. It must be something in my install.

Any ideas? Any input would be greatly appreciated. I'm getting SOOO FRUSTRATED!

 

something is seriously f***ed up then. the only thing i can this is to leave your meter on the remote lead for the deck and see if there is a significant voltage drop no that lead. other than that???????

 

If that was the case it still should have turned on when I used the jumper wire shouldnt it? Also I just realized that I didn't disconnect the negative battery terminal when I hooked it up. That wouldnt cause a problem would it?

 

no, that wont cause a problem. Try changing the fuse in your inline fuse holder. (even if it looks ok.)

 

Is there anyway to actually check the fuse other than just visual inspection?

 

If you have a multimeter, you can use the continuity tester, and put one lead on each side of the fuse. If it buzzes or beeps, then I believe the fuse is o.k.

 

You also have this posted in "install related." This forum is small enough that you do not need to post the same topic in multiple areas.
