Heres the deal. i have two brand new 12" MTX Power6000 subs that will be going into a custom enclosure that im building. What i dont have is an amp. The subs are 250W RMS max single 4-ohm voice coil, 600W max. Do i need an amp that can supply 250W RMS at 4 ohms or is one that supplies 125W RMS at 2 ohms ok to use. I dont want to spend more than $200 but i want to be able to bump my system pretty good. I also am getting a 1.0 farad cap. If possible i would like a MTX amp. Any suggestions. thanks
