sorry for starting a new thread about amp advice but could anyone help me out? :D

Well I'm a total newbie and my mother was really thoughtful and bought me a fusion CS-SW120 12" 1000 watt sub. I have a kenwood KDCMP149 head unit and i think i have composite speakers? I have no idea about their specs though... If anyone could throw me some advice on what kind of amplifier would suit me that would be tops unfortunately i don't have much money as i'm a uni bum so I'm not looking for anything amazing, just something to be just over par
