Okay i have a dvc sub which i have wired at 8ohms. my amp can only take 4-8 ohms in bridged mode, i had it wired at 2ohm but then my amp started heating up really hott. So yeah about how much power will i loose wiring it at 8ohm and are there any benefits to wiring at 8ohm? my amp is 400 watts rms. @ 4 ohm
