Boss BA-2900 car amp doesnt produce any sound

One day my BA-2900 stopped working for no reason. Seems power is on, cooling fun is working and all the fuses look OK. A pioneer sub is attached. So there is only sound in back speakers as they are connected directly to the radio. Noticed, when car starts the sound (although a bit disorted) gets pump to front speakers and the sub, to only disappear in a few seconds.

I have come across a similar problem before. if you are using the ceramic (glass, clear) fuses the solder in the end caps sometimes melts. you will not see the fuse blown, but the fuse may still be bad. try a new fuse to see if that works. also make sure no single stray strands of wire from a positive or negative wire are touching on the terminals on the amp. i hope this helps. ill keep thinking of other things in the meantime

Subwoofers Creating Independent Noise


Sounds like your RCA's are near your power & ground wires. I would run your RCA''s on the other side or as far away from the power wire as possibly. Sounds like your getting the infamous alternator whine. If none of the above work you can get a in line noise filter to filter out that noise. RCA's can pick up noise when their around anything that has alot of current running through it....Hope this helps

Boss 3500 Watt Monoblock Amp stops putting out signal


What's the battery voltage across the B+ and ground terminals of the amp when the engine is running?

Does the amp go into protect mode when the engine is running?

Are you sure the head unit is still producing output when the engine is running?

Not producing sound


It sounds like the power supply may have failed. I'm not familiar with that particular Boss amp but many amplifiers will light the power indicator even though the amp isn't operating.

Have you checked your speakers to see if they're blown?

Have you checked the wiring to make sure the speakers are still connected to the amp?

If this is the CH150, it's not bridgeable. Try connecting it normally (one speaker per channel) to see if it will produce output.

Channels Not Playing


i had afriend who is atechnician. his boss amplifier stopped working on one channel,so what he did is openened the amp,tested the mosfet transistors and it showed signs of failure.then he went shopping for same type of mosfet transistors and with no luck in buying the right type, he put the amp away for acouple of weeks. then one day he hooked it up and strangely it worked again. he told me that while it was hooked up itwent into protection mode and for some reason it worked later. so i would not open it because of static discharge i would disconnect the amp for maybe acouple of weeks then hook it back up.... its worth a try & good luck
