i have tryed alot of amps in all my cars, and i have found only 2 amps that i really like that are good clean sounding, and does what u want it to do at a 2ohm level, that being the Memphis Class D Digital 1100 Watt amp that is set for 2ohm stable, and the JL 1000/1.....either one of those will make them speakers knock like you wouldn't believe
