California Prop 65 Warning

What is Proposition 65?

Proposition 65 is a California law that applies to companies selling products in California. Proposition 65 requires warnings if a product contains any listed chemical present above very low levels. Proposition 65’s warning standards are among the most stringent in the world. Proposition 65 is not a product safety law, but rather a "right-to-know" law. Businesses are required to provide warnings to comply with Proposition 65.

There are over 800 chemicals on the Proposition 65 list, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The list includes naturally occurring and man-made chemicals. Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including electronic equipment, and warnings can be seen posted throughout California in a variety of establishments such as buildings, hotels, restaurants, coffee shops, and stores.

Why do you see the warning on our packaging and website?

The warning is part of our ongoing effort to comply with the California Safe Drinking Water and Toxic Enforcement Act of 1986 (known as "Proposition 65").

This small little guy worked perfectly for powering a pair of 4x6 speakers for my portable cooler speaker project. I hooked a 3.5m>RCA cable to it and used the volume from my iTouch. Small draw off the battery made it last about 7hrs

Wondering what's inside? A review for electronics geeks.

For those who might be curious about what goes into these things, here are some answers. A single inductor is by the power supply input, along with the one discrete (bipolar) transistor that appears on the circuit board. It seems like a circuit intended to deal with voltage fluctuations, and maybe confer a degree of idiot-proofing, and I approve. Most of the other parts in evidence are the minimum needed to do about a third of what this amp's spec sheet claims. Aside from some small value mylars and a couple of ceramics, all of the capacitors are Taiwanese, aluminum electrolytics. At least 3/4 of the resistors appear to be carbon-based. Buffering is provided by a UTC4558 dual op amp chip. Amplification is provided by a 4-channel amp-on-a-chip, the $2.50 STA540SAN. At 12 volts, this chip is good for 4 channels x 9 watts @2 ohms, but can be bridged to provide 2 x 18 watts @4 ohms instead. That's exactly what we have here. If I were making this...

So far so good.

I had a factory sub for a 2011 Honda CRV and the OEM amp is very small. This is the only amp I could find that would fit in the available slot on the sub. This with a slight mod worked well. First off after trying 2 of these amps the high inputs do not work at all, they should be deleted from this amp since they are useless. The RCA's do work well though. Just be aware you will need a Input converter if using a factory deck. The PAC input converter works very well. Another thing about this amp when the power goes on or off there is a thump sound from the sub. Its not too bad but it is noticable and it was supposed to have a soft on and off so another unexpected issue. I also noticed if you do not use the remote on/off orange cable the amp senses the inputs and turn the amp on and off. I wish the timeout for this was longer, the delay is only 1 second or something so the amp can go on/off alot if a song has no bass for a few seconds which is annoying. If the delay was 5 seconds it...
