**Need an amp to power a pair of JBL SRX728**

What would you guys suggest to power a pair of JBL SRX728 subs? I was thinking either of these :

Crown MA5000VZ (1 SRX728 on each chanel at 1,700 wpc into 4 ohms -- 20hz-20khz)

2 QSC PLX2502 (1 SRX728 on each bridged PLX2502 at 2,500 watts into 4 ohms -- 1khz)

2 Crown K2 (1 SRX728 on each bridged K2 at 2,500 watts into 4 ohms -- 1khz)

Camco Vortex 6 (1 SRX728 on each channel at 2,100 wpc into 4 ohms -- 1khz)

Lab Gruppen LAB4000 (1 SRX728 on each channel at 2,100 wpc into 4 ohms -- 20hz-20khz)

Would running each SRX728 sub on a bridged QSC RMX2450 be good or not?
