I know these arent the best amps but they are the only ones my buddy can get and he wants to know which is best to power his 2 12" Cerwin Vega VMAX! They are the new ones! He is getting them soon! But these are the 2 amps that another kid has for sale at school! a 1800watt Visonik or a Audiobahn 8002T amp! Which one will push those subs harder in a sealed box and will he need a battery or alt, or capacitor or anything like that or will he be ok with the stock battery and stock alt? o ya and he wants to konw if he would out thump 2 12" Rockford Punch 2's in a custom built ported box in a grand am wiht Pioneer HU and highs, if he ran either amp and the Cerwin Vega VMAX's in a custom built ported box with Pioneer HU and highs in a S10 extreme? What do u think who would win? Which amp would push the 1000watt VMAX's better? And would the Cerwin Vega VMAX's be louder in a ported or sealed box?
