My amp wont turn on its a swiss audio amp the only light that comes on is a protection light how do i get it to work?

The red light you describe on your amp, is the protection mode warning light. An amp goes into protect for many reasons. Here's a checklist.

1st check the fuse (s) on your amp and make sure they are not blown.

2nd check the inline fuse next to your car battery (if you have an inline fuse)

3rd, disconnect the speaker wires with amp on, does the light go off?

4th check your ground, this may be ok if you have tried another amp with the same wires.

5th.if none of these turns the protect mode off, it may be an internal fault.

you may have blown transistors and it is a tricky job to repair and costly.

Check for a speaker wire that come come of , Or a loose grond wire on the amp or where ever you have the ground wire connected two,

Disconnect the speakers and then try it again...there may be a shorted speaker or wire if the amp comes out of protect after you disconnect the wires...if the amp stays in protect after you disconnect the wires then there is a problem inside the amp with the circuitry and it will need to get serviced by an electronic tech

Hello mcis43fan,

The protection circuit can be activated by shorted or grounded wiring or it can be caused by a defect in the amp itself.

First, disconnect all wires except power, ground and the remote turn-on lead and see if the amp powers up normally. If it still goes into protection, the amp is defective, most likely shorted outputs and needs repair or replacement. If the amp powers up normally, test the other wiring for shorts and grounds. You can reconnect them one at a time to determine which one is causing the problem.

Hope this helps.

sounds like maybe a speaker short, try unhooking your speakers and then powering up your amp, if it then powers up with the speakers unhooked try hooking up each speaker one by one untill the amp goes back into protection and then you have your bad speaker.

sorry to have to tell u this but you blew your amp or just the channels this happens when you dont have the ohm rite for amp and speakers

if the Protect light is on, that would be bad, if the green lights on you've got power thru your amp, meaning you have a good connection

Check your speakers with an ohm meter. They should have some resistance but not totally shorted. Its prob the amp that got fried. Connect the amp to the battery with no speakers attached to it if the protection light still comes on then the amp is blown.

If the amp is blown you can send it to people on ebay and get it fixed pretty cheap. Good luck!

You need to check your woofers. Most likely one or both may be a) blown or at a dead short or b) the ohm rating on them may be too low. What model woofers and amp do you have??

Yes it is probably too powerful for those speakers. Or the speakers could be defective.
