So I recently took out my 2 12 inch 3500 watt max each dual voice coil subs and the 3500 watt amp steady 2 ohm I had running them from my gmc yukon. I needed more space for the kids and my tools for work and also noticed how bad it was draining my power. My question is would I be ok to downsize. I want to use 1 of the 12s I have and get a single sub box or make my own custom box and maybe run it off of a 400 watt amp. I heard somewhere that its bad for your subs to run them on lower specs then what they call for. I'm looking for a little more bass then stock and to not take so much space and power from my car I would love to use one of my subs instead of buying new but dont want to damage it by not giving it what it needs
