Finally bought a subwoofer.. need help choosing the right amp?

i purchased a new Alpine SWX 1243D subwoofer... its has DVC and does 1000w RMS/ 3000w Peak... Now i'm searching for an Amplifier (prefer a ClassD Mono) that will do or come close to doing 1000w of continuous clean power to get this Sub bangin' ... to be clear i just got one of these.... i will be running them parallel @ 2 Ohms... so suggestions people... ow im on a budget... anything under $400... also how would wire it to get the most out of it.... thanks!
