Stereo keeps cutting out!

It could also be that the amp is running to hot and turns its self off. Mine does it all the time

That could be the problem if the dash lights weren't coming on at the same time.

I was having a similar problem not too long ago.

My stereo would work fine, until I pressed the brake pedal. Once I did that (and the brake lights came on), the stereo would turn off.

If I turned on my headlights, the stereo turned off.

If I had the headlights on and I braked, the headlights dimmed.

It all comes back to a lack of supply voltage, the alternator.

A loose connection in the amplifier would not cause the battery light to come on, it's a voltage issue for sure.

just tested the battery and there is no great drop in the voltage while the music is up..... we tested the earth and there was no leak there was about 0.01 curent running threw it or ohms or wat eva they are called.

Were you measuring the voltage when the amp cut out? If not, do that and see what the voltage does. If you were, then see if the amp is hot when it is cutting out... Could be over heating. Also, what amp is it and how are the speakers wired to it? If the speakers are wired to be a lower impedence than the amp can handle, it can cause the protection circuit kick in at high volumes.

but that doesn't explain as to why the lights are coming on on the dash though....

 

[StoneX]

Nah, it doesn't... He needs someone to measure the voltage while he turns the stereo up to the point that the dash light comes on.

it is a jbl 520 watt amp. The speakers are wired to it liek this:

Pioneer splits hooked up on the bottom row and the sub bridged on the top line...

does this help at all

 

[StoneX]

So "(the front speakers and splits and the sub)" isn't right? You only have one pair of speakers and one sub hooked up to it?

What sub is it?

 

[liquidforce_134]

umm yeah i have the wire from teh amp goin to each cross over and then the wires from the cross over running to the tweater and the speakers like they are ment to be set up. and i got a sub hooked up to it which is bridged.

The sub is a JBL 1000watts sub i think its 250RMS
