Voltage- How low is too low?


Recommended Posts

A manufacturer will give a specified range to operate their device in.

As long as you stay in that range, then the product should work as advertised for its specific design life.

Keep in mind, as I mentioned above, some voltage meters may not pick up peak drops so the amp could be subjected to lower voltages then the user realizes.

Most modern amplifiers will have regulated power supplies which means that if the voltage drops, the input current will rise to allow the amplifier's power supply to stay constant.

With increased current comes increased heat (P=I^2*R). Heat loss would increase with the square of the current.

Increased heat inside of an amplifier will take an effect on the aging of its internal components, specifically the electrolytic capacitors.

Therefore in general, its best to keep the amp as cool as possible.

Of course, if an amplifier is rated down to 10V, it wont blow if you run it at 9.9V. The manufacturer will have some design margin in the product for reliability.

But the further you push the limits, the faster the device will wear out and fail.

Wick's you're the best..

Nah........

I just deal with electronic specs a lot so I tend to think about things technically.

i happily drop to high 11s full tilt giving demos. dem lows draw some serious current!

you are naughty to your amp and alt! XD

if the car doesn't stall, you have enough voltage.

havent damaged an amp yet from low voltage. my alts may hate me but they bounce right back from that load. having a 370 and 270 is a BIG help!! but my 12 wet group 31s are killing me... hoping to throw 12 34 agms in soon then 6 more.... 18 34s should be good :)
