First post here.  I purchased two pre-owned SubM HPs from the original owner, mentioned they're 3-4 years old (purchased 2011-2012).

I would turn off both subs manually when not in use (for the last couple weeks)...only use on the weekends.  Today neither one would power up when I manually switched on. It was really odd because both would not power up, but are plugged into different outlets.  I then noticed when I cycled the switch a few times, i would see all lights light up for a milli second when cycling off.  Then I continued to switch on/off about 5 more times, then it powered up.  I did the same with the other, and it powered up finally.

During the span of a movie, I did hear one of the subs, clicking, like the power to the amp cycling off/on....similar to the sound when manually switching off then back on.

Is this a sign of something wearing out?  would this be a simple part replacement, or would need to change the whole amp plate?  Everything else seems to work fine.

thanks,

chris

I'd suggest shooting Mark an e-mail or calling tomorrow during normal business hours.  He may have some tips for you, and can definitely answer your questions.

Thanks for the call this morning Chris.  Glad we were able to sort things out.  For those wondering, these were some of the first HP Upgrades sent out in late 2010, and shipping them in for an update to current wiring and control programming (no relation to our audio DSP) will resolve the issue.  Not all had issues, but this was a very early update to the amplifier after we started shipping the 2400W HP's.  This was the first among many minor tweaks which improved stability and reduced the number of amplifiers issues over the years.

Watching others jumping to ship out the new SpeakerPower amp options has been entertaining to say the least.  The more users of various designs and the more varied the test environments, the more stable and reliable a product becomes.  Speakerpower has always been a great supplier to work with and very responsive to the unique needs of our home audio applications.  From the first 1000W ICEpower amplifiers from SpeakerPower we shipped back in 2006 (9 years ago!?!) there have been continued updates and polishing of the amplifiers, their assembly, reliability and other details which don't show up on a maximum output charts but all improve the experience in your home.  Our original 1000W ICEpower amplifiers are still more powerful than the 700W, or sometimes labeled 925W [rolleyes], new amplifier offerings.  I've been involved with the feature set development and field testing most of the new amp models.  We all benefit from the quirks caught or improvements made, and it happens faster with more of us involved.  Of course some of us have learned to not promise items which aren't yet finished, or at least leave a much bigger buffer than what we might be hoping for.

Thanks Mark!  These replaced a single SVS PB12-NSD...the sound from 2 SubMs are soo satisfying. [smile]

See, Mark's like the pied piper of problems.  He's got a special ultrasonic pipe that he plays while you're on the phone with him.  You can't hear it, but his products can and things just fall into place while he plays. [tongue]

If that fails, you ship the amplifier back for repair with the 10lb sledge. [eek]
