What does this mean 1 x 1500 @ 14.4Vdc, 4 ohms Mono, 1.5% THD+N RMS POWER In Watts, All Channels Driven 1500 x 1 @ 4 ohms, from 20-200 Hz, 14.4Vdc, 1% THD CEA-2006 (Watts) Signal to Noise Ratio -46 CEA-2006 (ref: 1W, A-weighted)
If you have 2 single voice coil 4 ohm subs, you will be running the amp at either 2 ohms or 8 ohms. if the amp is 2 ohm stable then that is ok. If it is you be giving the subs(just guessing) around 1200-1500 watts a peice. If it isnt 4 ohm stable then you must wire it to 8 ohms. You will only get 350-400 watts to each sub. If the subs are dual 4 ohm then it will work better. You will want to wire the VC's in series and the subs in parallel. This will give your amp a 4 ohm load giving each sub 750 watts. Also, most stock electrical systems put out 13.8 volts when the engine is running. And most stock electrical systems can't handle a 1500 watt amp. If you run the amp at 13.8 you will lose around 100 watts. Not a noticible difference.
