GARBAGE>>>dont buy it but if you do here is how to fix it
Crutchfield Customer Review (What's this?)
Its a 3 star when it works. Its zero the other two times the thing has blown the two voltage regulators the power supply pcba. So here is my experience. Had it for just under two years and 2 voltage regulators overheated and burned. Crutchfield sent a replacement power supply since still under warranty which fixed it. It took 9 months for the same to voltage regulators to blow. I use it for ordinary surround sound use. Not loud, nothing crazy so there is an obvious design issue. The 2nd time it failed, I read the reviews and saw that everyone else was having the same issue. I got online and downloaded the shematic and ordered the two voltage regulators that burned up, for get this $0.76 each and because I am an engineer and have access to the soldering station replaced the two components, and then fabricated two aluminum heat sinks and screwed them to the back of the replaced voltage regulators and off we go. I have been running it for two weeks and so far so good. The reality is The subwoofer has a fundamental design issue and the heat sinks I added should dissipate enough heat to lower the temperature on the voltage regulators enough to prevent this in the future. If you are one of the many who have fell victim to a poor product like this, ask your Electrical engineer buddy for help on this one. It takes about 10 minutes to repair. Best thing was Crutchfield asking me to buy another. I was like you heard me say its already failed twice right?
Pros: sounds good when it is working before it burns up every 9-24 months.
Cons: Obvious design flaw that infinity should have taken care of.Crutchfield response on 12/27/2012 Please note the following: (1) Modifying your equipment will void your existing warranty (2) It may be dangerous to perform work on an electrical item.
