When i turned the bass up to high on my head unit my amp cuts out on overprotection, just for a second and them comes back on. why?


go into your settings in the deck by holding down the volume on most models for 10 seconds then change your hpf settings and your lpf settings your bass will sound much better and not cut out. hpf recommended 160......lpf recommended 140.... good luck

Technics amplifier su-v98, cuts off at 22-24 desibls


The most common cause of this is defective coupling caps inside. These allow some DC voltage to pass through to the final amp stage. This DDC voltage is detected by the protection circuit and the unit shuts down. This unit will require service. Please note that this should be a simple and inexpensive repair. The cost should be less than $10 for parts.

Sonamp 260 cuts out


Normally this denotes a protect condition. Remove the speaker wires from the back of the amp and see if the green light stays on. If this fixes the problem, then there is a short circuit in your wires, speaker level volume control or speakers. The amp sees the short and goes into protect. After a couple seconds it closes the connection again and if the short is still present it goes back into protect.

Amplifier power cutting out


not enough power to amp and or amps location is too hot might want to invest in a couple cooling fans from computer store and attach where needed

an amp should take up to 3/4 load but when not enough air to it to cool it off it will shut down

try this turn gain all the way down and slowly work up too desired amp volume setting

Sounds like you like your music like me... LOUD. If you've done this a number of times, there are a few things that can happen:

1. You've blown the speakers... but you've said it operates for 2 seconds, then cuts out.
2. You've damaged the amplifier modules within the amp and they immediately overheat upon power-up. Does the music come back like 5 or 10 seconds after the unit cuts out?
3. Thermal switch has malfunctioned and just cuts off the power to the amplifier modules as soon as it sees any heat.
4. If you've gotten the amp really HOT during playing, it's possible that it's as simple as the amp modules are only intermittently connected (fatigued/stressed or cold solder joints) at the on the PCB. Just resolder the connections of the amp module to the PCB. I've seen that happen numerous times and that's where I'd place my money.
