NHT SA-2 Amplifier Popping Noise

I have a NHT SA-2 amplifier hooked up to a NHT 10" subwoofer. Once the amp warms up I get loud popping noises coming from the subwoofer. Any advice is appreciated on what I need to do for trouble shooting this issue.

SOURCE: I have a NHT SA-2

sounds like speaker is clipping (overdriving) put a meter onthe disconnected speaker and see what the resistance is,4 ohms ,8 ohms ,if the meter wont stay in one place (numbers changing constantly) you have a burnt or damaged coil in your sub, if that is not the problem change your RCA's cables to make sure it not a bad wire including speaker wires! GOOD LUCK

NHT sa-2 amplifier won't go into standby mode after 10 Minutes of no signal


Does the NHT sa-2 have it's own pre-amp? Because I'm wondering if the power off only works when it's own pre-amp is used? So when your receiver is connected it's shut off.

You could try something connected to it's own pre-amp (if it has one) and see if it goes off when there's no signal from that.

Popping noise


Check the sub with a multimeter. It should read the ohms it is rated at when you hook it to the positive & negative inputs. It its off your coil if bad.

My su-g95 technics Stereo integrated amplifier wont play any noise. and when i adjust the volume it makes a popping/crackling noise. i am 100% sure all the speakers were hooked up correctly.


Well it sounds like your amplifier IC's are working correctly since you are hearing that pop. I have the same amplifier and every 10db increment it pops. Have you tried every input? Possibly try starting at a low volume, plug an RCA plug into CD or any other input, and touch the center prong of the other end of the cable. You should get a 60hz hum if your in the USA, otherwise it will be 50-55hz. Regardless it should make noise.

Subwoofer thumping when turn on


Your subwoofer is not getting enough power, or it is grounding out due to a bad connection. What is powering the subwoofer? You might want to consider buying an AC to DC power inverter and a car amplifier to power your subwoofer. You connect the AC/DC inverter to your amp the same way you would in your car (+) to (+) and (-) to (-). The only other thing you will have to do is run the remote wire to the (+) on the amp. You can buy the AC/DC inverter at radioshack for $49.99, and all you really would need is a 200watt max amplifier and that would cost you about $10-$20.00 for a cheap one.
