Amp has no power! HELP!!!!!

[Ranga]

Hi,
I have a Xplod amp with
X2 Front factory tweeters
X2 Parcel shelf 6x9's
X1 Explod amp
X1 JL audio 12" sub
__________________________________________________ _______________________________
Ok, my problem is that i have no power to my amp. The positive terminal recently broke and when touched on the place where the terminal goes i had power. It sparked a couple of times because it touched the negative. I checked fuses and put multimeter on the wire to the amp and i have power. it must be the amp. PLZ HELP !!!!!

[somefool]

Try with another amp to prove that the cables r fine. maybe REM cable got shot when the short happened...
if not fuses then most likely ur amp has passed on
but really the fuses should have blown b4 any damage could happen to the amp. hmm..

Check the amps fuse. You may of even blown the amp.

[Verynice]

remote wire hooked up?

[Timmos]

Yep - i'd also be guessing it's the remote wire.

Run a seperate wire from the headunit remote power outside the car to your amp.. If that fixes your problem you know there's either a short of a cut line somewhere.

[Verynice]

get a small bit of wire and bridge/connect the positive and remote terminals on your amp together. If it powers up your remote wire is at fault. If not the amp is probably fried.

All you need is a circuit tester.
I had the exact same problem as you mate, i was pulling my hair out for days. all it ended up being was the remote wire.
And i figured that out by useing a circuit tester

Hey,
Thanx guys
i got a multimeter and looked for power coming out the positive negitive and the REM cables disconected from the amp and i found.....
Positive: 13-14 amps or volts (whatever it is measured in i get confused)
REM : 13-14 whatevers
Negative i got no power at the terminal so i did it on the wire itself with the car runnning and CD on and i still got no reading. Its not fuses cuz there bridged.
What do i do now?
Ranga,

You shouldnt get anything from the negative. Volt meters measure the potential difference between two points. 0 volts measuring at ground and the earth terminal is a good thing. seeing as you have more than 12 volts at both PWR and remote, then id say your amp is at fault, try another amp if possible

[Ranga]

Yeah thats the thing i dont have an amp and im broke at the moment lol. Im gna save up and go to strathfield and buy a new sub,amp and get them to wire it up for me lol

[mummbles]

do the Sony amps have any internal fuses? I know a lot of others do.

In response to your readings, Say this is at your Amplifier:

[ + ] - [Rem] - [ - ]

With your Multimeter, When you held the probe on + and Rem terminals, Where did you get your neutral from?

Then when you did it to your - terminal, Where did you get your positive from?

Maybe i have missed something, I just didn't clearly understand your testing...

[Ranga]

Nah the sony amps have 2 25amp fuses

In response to your readings, Say this is at your Amplifier:

[ + ] - [Rem] - [ - ]

With your Multimeter, When you held the probe on + and Rem terminals, Where did you get your neutral from?

Then when you did it to your - terminal, Where did you get your positive from?

Maybe i have missed something, I just didn't clearly understand your testing...

Wen i used the multimeter i put the negative probe on the boot lock bar as earth and put the positive on all of the wires.

I reckon its the fuse in the amp.... open the amp up and test the fuse (or just look at it to make sure there is still a bridge/connection in it)

[Ranga]

Ok will do that now

[SuperSixty6]

Wen i used the multimeter i put the negative probe on the boot lock bar as earth and put the positive on all of the wires.

Ok, So you should not have got any reading when you had one end of the probe to the boot latch, and the other probe on the negative? Correct? Did you then test your negative terminal on the amp to the postive on the amp? Did you then get a reading?

I am just thinking along the lines of that your amp doesn't have a negative. Is it earthed correctly in the boot? And when the work on the battery was done, (I presume you run an external fuse in the engine bay) was that removed by chance hence no power?
