so if they are the 2 ohm per coil, DVC subs, you either need an amp thats 2 ohm or 1/2 ohm mono stable or one thats 1 ohm or 4 ohm stereo stable. Most "mono" amps are ones that are already bridged internally and therefore only have one output channel. I did 2 of those same subs on the Power Acoustic LT 980/2 running at a 2 ohm bridged, and dam it hit hard!
Some thing happens inside a radio. Ever wonder why you can almost never bridge a radio and the speaker outputs are high in the THD? They are bridged already and cant be bridged again, just like a 4 channel amp cant be bridged into 1 channel
Having a mono amp paralleled to 1 ohm (operates both voice coils) means having an amp stable at 1 ohm, which means alot of money. Don't have the time to see those amps that x6369x recommended, but you'll have to check into the capabilities. Good thing about mono amps: specific for bass applications, usually filter out lower frequencies that you can't here anyway (which could cause distortion), and some are built as if they all ready have capacitance to keep the amp running more efficient.
