My audiobahn 18001DT amp isnt getting enough power out of my car a 2000 Mazda Millenia S. The stock alternator is putting out 110 amps the amp is drawing 150 amps to put out 1800 watts to 2 12" audiobahn ultra excursion subs. I have upgraded the battery to a optima red top and have installed 2 1 farad caps. When i have the car running the amp recieves 13.5-14 volts when i have the bass turned all the way down. When i turn the bass up half way the voltage drops within 5 minutes to 11.5. I currently have 4 ga wire planning on upgrading to 0 ga to stop some of the voltage loss cause im running the wire 20 feet. should i upgrade the alternator or put more caps or a battery? also im planning on building a new box and i want these subs to be loud so any tips or advice woul;d be helpful. thanks My Millenia
