I just got a pair of polk momo 12" subs. I put them in a sealed box with .9 cu ft per chamber. THey are rated at 400 rms and 800 peak. THey are single 4 ohm voice coils. Now i have $200 i am willing to spend on an amp. I only need it for the subs so i would like to go Class D mono. For $200 what would you guys get, i have some in mind, but lets see what you guys can come up with first.
