SOURCE: My amp wont put out sound

If your amp powers on with protection light, try the following: Unhook all input RCA cables on the amp. See if that helps with protection light. With a DMM, measure the voltage going into the amp's power connectors. If it's less than the minimum required by the amp, protection will kick in. Also, check for over voltage, too much volts can also trigger protection. Check your speaker wires for short. If some of the wire strands are loose and touching each other or the chassis, it can cause protection. Basically try the amp with no RCA inputs, no speakers attached. If the protection doesn't go out, then you have an amp problem.

SOURCE: Protect light flashing/ticking

Yes make sure your powers and grounds are all ok. If you have round glass fuse in the power wire replace it even it it looks good. Ive seen those fuses melt the solder internally so they will be "blown" but look as if they ar eperfect.... if that does not help your amp needs repaired. go to my website at http://home.comcast.net/bigmikeselectronic/repair for more info. I may be able to repair it fo ryou or buy it form you as-is...

SOURCE: car amp

The most common reason for this is shorted output transistors. To confirm that the problem is in the amplifier, disconnect all speaker wires and the RCA cables. If the amp still goes into protection, check the DC voltage across the B+ and ground terminals. It should not drop below 11 volts. Also check the remote voltage.

If the amp continues to go into protect with no external connections (other than B+, remote and ground) and the voltage remaiins above 11v, the amp is defective.

SOURCE: Amp Power light will not go on. Protection light is lit- Thump sound in speakers

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

I had my boss 2400 watt 2 channel amp hooked up in my car. I had one sub on each channel and one of my subs blew. I unhooked the positive speaker wire on the blown sub, everything was fine. Driving down...


If your amp started smoking, probably not. Due to your description, did the other sub really blow? I would hook it up to another amp to test it. It may have been a channel in your amp. As for repairing the amp, the parts and labor to repair will probably cost you more that to just replace the amp.

Why is my sub heartbeating and my amp in protection mode


Sounds like a shorted speaker wire. Try disconnecting speaker from amp and see if protection light goes out- if so replace bad speaker wire. Only other issue i can think of from your short description is that you might have a bad ground going to amp or the remote power wire is bad. try running a new ground wire to a clean metallic spot on you cars chassis close to where the amp is located. Good ground = good clean sound

BOSS AUDIO SYSTEMS SE950 Car Audio Amplifier: I have a SE950 boss amp, hooked to 2 audiobahn 12"...


Sounds like you are over working this amp for sure.. Upgrading your power wire & battery might help, check your gain level on your amp to. This is not the volume for the amp. Its to get both amp and the cd player on the same page... And most of all if your subs are wired up to .5 ohm stable, see if your amp do the same... My answer to this ?? Upgrade your amp, Boss audio was never a good company to me, but that is my opinon. Audiobahn set up all the way..

ALL THE WIRES ARE RAN CORRECTLY,THE GROUND IS SECURE UNDER A BOLT UNDER THE SEAT,THE SUBS ARE HOOKED UP RIGHT,BUT THE PROTECTION LIGHT IS STILL ON


the protection is on because if any speaker has internal electric problems as open circuit or short circuit, need to be checked

Speakers cut off when bass goes up


probably the amp going to safe or protect mode judging by the fact that you have 3 subs wired to it i would say it is not 1 ohm stable try disconnecting 1 sub and see if it still happens this will be running a 2 ohm load rather than 1 if it stops happening then you need to figure out a better wiring configuration that will work with your amp.

Red light


something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.

Low amp output


Make sure the BOSS isn't in "Protected" mode (Red led lit) and connect the speakers properly (check the connections if they are in "bridged" mode).
Also, make sure you set the cross-over, bass boost setting, bass volume control and the bridge mode according to the speakers you are connecting. Check the input level too.
The BOSS amplifiers are of very poor quality and it can be easily broken. Maybe yours is broken.
