Question about Infinity PS-10 Subwoofer
I have an Infinity PS12 Subwoofer that is clicking in and out of standby after it warms up. I am running it in the inputs that take the line-level inputs and have the LFE turned about half-way up. Any ideas of what I could check?
Unfortunately your subwoofers amplifier circuitry will need to be repaired ,the amplifier is bad and kicking in to protect mode. This mode is designed for safety of the unit and user and sub should not be operated until repaired as it may incur more damage to the components. I hope this helps.

I've got the same problem with my PS-10 from Infinity. It works great for about 30-45 minutes, then click in and out of standby mode. It sounds to me like a overheating safety fault. When I take off the amp panel (unplugged), it feels quite warm, and you can see that there is really no way for heat the escape. I tried running it briefly with the amp panel outside and it seemed to work fine! Since I'm out of warranty, I think I'll try cutting some ventilation holes. I noted there are 2 oval shaped holes near the bottom (just above amp), but covered with the panel sticker. I'll try cutting those open first.

Same problem-I had my PS-12 repaired about 1 year ago under warranty. Problem was identified as- repaired power supply by replacing two capacitors. There was sign of circuit overheating. Problem has reoccured. Looking for larger voltage capacitors to R/R. My assumption, great speaker but bad design by Infinity. I need schamatic to have better idea for repairs, could be something else burning the caps. Any ideas!
