Please read new member posting guidelines and fix this topics so we can help you better, Thanks. Way more information is needed on your part: budget, electrical upgrades, etc. Max wattage doesnt mean a thing, find you a 2000 watt rms amplifier that will fit your budget, why get two amps instead of one. What voice coil rating are your subs? (see how this information could have given to us to skip all these questions Im asking you). i dnt have a budget, money is no problem and both of my speakers are 2-ohm's , and i just thought 2 amps would be better cause u can run more wattage to each speaker. give some suggestions
