I need an amp to power these RE8's. 175 RMS each dual voice coil at 4 ohms. so i need something that can do 350-400 mono at 4 ohms or 150-200 x 2 at 2 ohms...i was thinking the MTX 342 or the MTX4002...i would like to know some more that would work so i can get an idea of what i have to choose from..i dont want to spend a lot on this.
