Ohhh I think I heard something about that. How well the amp can make the woofer move from a stand still and vice versa. Makes the response tighter and I right?It’s basically how well the amp can control the subs. I can explain way more in detail, but I think there’s quite a few various factors that play into damping factor. One is half bridge and full bridge amps have different styles of power supplies, and with the way I see a lot of full bridge sub amps done, it’s done to be cheap power, so there’s consequences to cheap power with these modern day full bridges. Wattage is not wattage, in that case, to an extent.
