[QUOTE="vario, post: 4540577, member: 583966"] No that would probably be okay. Check how you wired the sub. That determines the resistance. To do this, take the multimeter and measure the resistance of the plus and negative wire that would run into the amplifier (Do not do this with any power running through and disconnect the two wires from the amp before) It should say either 2 or 4 I would imagine. You can't just send a particular resistance out of the amp, the speaker coil's dictate the resistance based on wiring. Your formula is correct assuming the D4 sub can be wired to 2 ohm and you wired it correclty to 2 ohm, you want 31.62, maybe a little less. Clipped signal is an amp problem. If you set gains correctly using the multimeter you will not clip the sub unless the amps are overrated garbage. It basically means the amp is working too hard to amplify a signal to a particular voltage. This causes it to the cut the top and the bottom off of the sound wave which distorts the speaker. Giving a sub more power than rated and giving it too little power probably shortens the lifespan but its not the same as clipping the sub. I wouldnt worry about giving it too much power or too little power provided it is within +/- 100-200 watts rms anyway. [/QUOTE]
