Protection light

[pete Stockbauer]

I have a skar RP 150.4 now when hooked up to remote wire the protection light comes on.Grounds are good all new wire and still on.If I jump it to a 12v ign source it doesn't come on I even tried 2 other head units seems the remote wire causes protection light to come in even if I hook it up to my DSP remote.Anyone had these issues I sent the amp back it was checked out all good

Have you tried this with the speaker wires disconnected?

 

[pete Stockbauer]

Yes and hooked up sane thing

I have never experienced a protection light coming on due to low voltage. That's a new issue, for me. Could your remote wire be pinched and grounded somewhere and causing your amp to see a lower voltage? You say your ground and power are good, and your speakers are disconnected? But you turn on the radio and the amp goes into protect, but if you connect the remote to a 12v switched wire, the amp comes on? Does it play music?

 

[pete Stockbauer]

It plays even with protection light on and remote wire test 12v but hooked up too a 12v ignition source the light don't come on speakers hook up

If it's under warranty, contact SKAR.

I sent it back too them they tested it and said it's good had to be something in vehicle then

What make/model of car and which wire did you try to use? Not all wires that show 12VDC can drive anything that requires more than a few milliAmps- did you connect that wire to the fuse block or tap into a wire for something else?

The manual shows the reasons for the protection indicator illuminating- does it happen as soon as you turn it on, or after it has been on for awhile?

Soon as you turn it on the protect light comes on when hooked to radio or remote on DSP and the remote wire is 20awg

I just saw that you sent it in- did you use the recommended power wire gauge for your model AND did you increase the size of the ground wire from the body to the battery? If you don't, that skinny ground wire will never let the amp perform and it can cause problems.

Voltage and Current are two completely different things.

Am I correct in thinking that the amp works, but the protection light is on? That's how I understood it from one of your posts. It may just be low voltage- are you measuring this at the amplifier, at its main + and - terminals? You need to do that- if it shows less than battery or charging voltage, read my other post about the body ground wire.

Remote turn on circuits use very little current. As a test, turn off everything in the car (and remove the key from the ignition switch), disconnect the remote turn on wire from the amp, then connect the remote terminal and positive power terminal. If it turns on, you need to do something different for remote turn on.

The head unit- what is it? The combination of the DSP and amp may be too much for the circuit in the head unit. Need the brand/model.

Will have to wire it another way works fine if I jump remote

See if the existing remote turn on wire will latch a Bosch-style relay- if it does, use that to provide the 12V from the main power cabling at the amp- the relay can handle at least 30A and only draws up to 150mA, which shouldn't be a problem for any head unit.

This diagram will work-

It could be the dsp

I'll try the relay and see what happens

Do you have a multimeter? If not, you really need one and you need to use it to measure Current and Voltage. If you haven't measured Current, the meter is connected in series with the wire and terminal. Also, remember to set the meter to Voltage afterward, or the meter's fuse will blow. If it's not protected, the meter can be damaged- use a meter rated for 10A.

DO NOT use a test light with regular incandescent bulb if you don't know what the wire is supposed to do- some circuits are too sensitive for the Current draw of a bulb (ECM and other modules).

Set the meter to measure Current, then connect one meter lead to the remote turn on terminal on the DSP and connect the other to the amp's power cable. If that's more than 150mA, contact the manufacturer and find out what needs to happen, to get it right.

Measure the Current on the remote turn on for the amp in the same way and do the same if you need to turn on other electronics. Add the total of them and use a relay if it exceeds 150mA. I don't remember any head units that were capable of delivering more than that number and even home AV equipment has the same limit for remote turn on.

Based on what you posted, the amp appears to be your problem. Tell them to send you a replacement. I've installed many amps, and never experienced what you described. Keep us updated on your solution.

Does the remote turn on work? That’s 12 volts. AAA batteries to the remote? Or Lithium batteries. There should be no power wire to the radio from the battery.

After checking it out when I had time turns out my ground was the issue I grounded it in a different spot after I cleaned up the area and it was fine ground wire little bit longer but it works
