no clipping was involved i have tuned my amp with an oscilliscope...... my headunit does not send a clipped signal until around 29 and i never have it turned past 24........my amp is rms around 900 watts into 2 ohm at 12.6 volts so id be reaching somewhere near maybe 1k watts and the subs rms is 1000 watts.....by the way i am a mobile electronics student with minor in basic electronics principles....i have done all the math checked and rechecked it and there is no way my install or calculations are incorrect..........ground i perfect, signal leads not run next to power cable, big three done, new red top battery, fuses not blown and in line fuse rated up to 160 amps.....i think that it was just a faulty tinsel lead
