voltages

Hey I was wondering how much of a power difference there would be in .6 volts. Example, if an amp is "rated" at 900 RMS at 14.4, how much would you lose at say 13.8? Also power acoustik doesnt list damping factors, and they dont have any if you ask them for one, so does that mean there pretty low or non-existent? thanks

Depends on how tightly the power supply is regulated.

But even for an unregulated design, the difference won't be enough to matter audibly.

That assumes your electrical system is actually stable at 13.8V

Well, too low of a damping factor isn't good (well, it could potentially be good depending on who you ask //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif )

And it's not possible for damping factor not to exist. A working speaker will always have a load impedance, and a working amp will always have an output impedance....and damping factor is simply the ratio of these two impedances.

But the simple answer to your question is that most solid state amps will have a high enough damping factor as to not audibly affect or alter the sound....so it's not a specification of importance or relevance in regards to solid state amps. You aren't in the dark on anything by Power Acoustik not being able to provide this spec to you.

I checked mine with my dads meter and it looks like im stable around 14 with low drops, thanks i didnt know how much of a difference there would be.

You spoke of solid state amps, so im assuming there are tube amps as well, and if so they're most likely more $$ lol. I'm torn between a Kicker ZX750.1 and the Power Acoustik OV1-2000D, the kicker i know will do great, its just right on the line of my budget. The PA, is perfect, i just dont know how good its gonna be in comparison to the Kicker. Do you think it will do a real 900 watts @ 2 Ohms? And sound good doing it? Also which would be less stressful on my car as i am still on stock alt for now? Thanks
