i am looking at the Alpine MRD-M605 amp. I have two 12" type r's that are the old 300 watt rms that are 2+2 ohms. does it really matter that this amp is 600 rms at one channel, that still provides 300 rms to each sub right? Or do i need to get a two channel?
If your subs are 2ohms DVC, then follow the above instruction and you will get 2ohms total load for the amp. The amp is 1 channel (mono). So to power both subs, you will have to use series wiring on it. 300w rms to each sub.
