Does Gain control watts out of a amp?

perfect answer....so is that why it is better to have high voltage pre-out on your deck because then you can have the gain lower on the amp, thus cleaner and less noise??

High voltage from the HU is only an issue when you are picking up noise. If you're getting the output that you need from the amp and not getting any hiss from the thermal noise in the interconnects or the amplifier's preamp, going to a higher voltage output from the HU will garner you no benefit. For the most part, makers advertising high voltage preouts is just a marketing gimmick. More is always better, right?

also, if you were trying to set the gain to something less then what would get you maximum undistorted power, you'd want want to ensure you'd be able to set the amp to that level. If you've got an 8V preout and an amplifier that accepts 0.2V to 2V, then already you're overdriving the input, and will want to adjust the preout down below 2V in order to get the desired output.

I been having a Tantrum 1200.1, dont really want to get rid of, I rather just keep this, and want some shallow mount subs, question is does gain and measuring the AC voltage out of the speaker outputs control how much wattage comes out?

temper tantrum?
