I have two 12" R's coming and I am going to power them with a JBL 1200.1 You can get these cheap on ebay and they are great amps! Rockford fosgate are also really good amps! Hope this helps.
how many voice coils on your subs? The DVC wich I have are 300w RMS per coil. What you want to do is get an amp with the same RMS or even a little more RMS than the speakers. The peak power doesn't really matter. If you match the RMS power on the amp to the RMSpower on the speakers you will have no problem powering the subs.
Hold Up!! Misconseption!!! It's not 300 watts per coil on the dvc its really 150watts per coil. So get an amp with an output of 600 watts. Alpine MRV-1507 will do the job. or esx q-2751.
