Ok, I got a Kicker SoloBaric S10L5, and i dont no much about amps, im only planning to power this sub, which should be good enough for me. The sub reads on the box:

Maximum recommended amplifier ( watts peak ) 900
Maximum recommended amplifire ( watts RMS ) 450
Frequency response ( Hz ) 24-100
It also says 4 0hm om the box

so would i need a mono amp? or a 2 channel or what? i just need a decent amp between 200-300$ or less and i should be fine, it also says: Dual 4-ohm voice coils for wiring flexibility, i dont really no what that means but all i want to no is what kind of amp i need and how much it will cost to do an ok job on this sub.
thanks in advance

 

A 2-ohm stable mono amp that pushes between 450 and 550 RMS should do you just fine. The Kenwood 9102D would kick that things ass, just be careful with the gain. Also, the Alpine MRP-M650 would do the job just fine.
