Okay, so I have 250 amp alternate in my car. I also have Hifonics Zeus ZRX3216.1D 3200 Watt Monoblock Amp, and then a 4.25 cubic feet box tuned at 37 hz. I was looking at the mojo m3 and Hd 15.. I was wondering which sub would be louder with the set up that I already have while listening to only...
