I was comparing several 5 channel amp specs. Some are rated at 14 volts. I'm going with eD's "NIN.5" which they rate wattage from 12.5 volts.
SO does that mean that if my 1/2 ton truck comes with a stock heavy duty alternator that keeps the voltmeter just under 14v, will I be getting a few more real world watts -particularly from the sub channel?
Feel free to point me to a previous post... I looked.
that just means how many watts they will push at that voltage. for example
if the amp is rated at 12.5 like Eds, and it says 400rms @ 12.5v that would mean that the amp probably does around 500 - 550rms @ 14v.
if the amp is rated at 14v like other companies, then thats all the rms that it will do at that voltage and when u drop to 12.5v u will be looking at an even lower wattage.
even if there is a significant (20%?) power increase by the addition of ~1v - which dpends on the degree of regulation used in the power supply - 20% isn't enough to make much of an audible improvement.
