What are the effects of powering a 14 volt system with 12 volts? Answered
I have some older, but nice yamaha computer speakers. there is an external transformer, and it says the out put is 14v dc, 800 mA. I am wanting to skip the transformer, and us a 12 volt sealed led acid battery battery to power them, placing it after the transformer. I would prefer to use the 12v battery as a 12v 5 ah battery is around 25-35 dollars, and a 14.4v 2ah battery is around 70 dollars.
Would this do any damage to the amplifier circuit within ? What effects would this have on the sound quality of the speakers? Would I be able to be switch from 12v dc, skipping the transformer, and plugged into the wall using the tranformer if i wired it to be able to do so, and would that have any long term effects on the speaker?
