lay off the bass adjustment. If you want to play with that. turn the bass adjustment to max on the deck before you set the gains. Therefore, you will never blow your subs even when you turn the bass boost to maximum.

lower volume = lower watts . turn it up and there will be a point when the headunit or amp would start to "clip". In layman's term, think of your sub suddenly receiving twice the power 1000w to 2000w when it gets a clipped signal.

Best way to set gains is to.
1. Turn gains all the way down on the amplifier
2. Turn up headunit until about 80percent of total volume( headunit will clip too therefore not turning it over 80percent would be safe, if the signal is clipped you blow your subs)
3. start turning up the gains on the amplifier until the subwoofer starts distorting then back down a bit.

This way, you will never kill the subs again.
