i am currently running a us amps 1600.2 to a 3510 in a 1.55cuft box with 24sqin port and 16 depth port at around 40 hertz. my amp bridged is supposed to put out 1100 watts at 4 ohms continous. i had it tested and i got screwed this thing puts out 720 at peak with 14.4 volts but as soon as voltage levels out it plumits. what im asking is what are some good mono amps with true wattage cause i keep getting screwed with amps. i want to run anywere from 1200-2000 watts rms at 1 ohm. by the way im only running stock elec with beefed up wires and 60 amp alt with high end batt. i get about 13.8-13.3 voltage with car running so i need something effecient. this highest i would like to pay is 450.00.
