So I want to put these subs in my suv since they have been laying around for years. I need to get an amp and just a few questions about it. There 2 12" infinity reference that have RMS wattage of 300 a piece so 600rms watts total, 4 ohm. I have been talking to some people and some say just run a mono amp, others say 2 channel amp. I can get a mono and drop it to 2ohm setup, or 2 channel and keep 4 ohm. Its a sealed box and I mostly listen to rock music. What way would you hook up some subs? I know theres some different setups and just curious which way I should go.
