I have a 12 to 14.4 volt power supply and I hooked my Alpine mrv-t503 amp to it to power my 2 12 inck kicker comps in a sealed box in my house, Just wanted to hear them befor I installed them into the car, Sounded good the most I did draw was between 10 & 15 amps so I was good to go. I also have a 10 inch Precision power dvc flat piston comp sub in a ported box, when I ran this sub I drew more amps than I did running the kicker comps in a sealed enclosure, I ran all 3 subs with 75watts @ 4 ohms. So why would a ported box draw more amprage than a seald box?
