Do NOT get a bigger amp than those kicker subs are rated for rms - unless you like expensive smoke shows (They will FRY overpowered) - That amp is TOO MUCH... You need an amp that puts out 1600 rms @ 2 ohms, NOT 2400so if i was to get 2 would a i still use 1 amp cuz then it would be 1200 each right? or would it just do 1? im not sure on how it all works together but i thought it would be good to have extra for "peak" thats what some cites said...
