[QUOTE="1aespinoza, post: 8849116, member: 654802"] First off, welcome. That wiring method is called parallel. With this method, the more speakers you wire, the lower the resistance gets. At 1 Ohm as described above, the amp is rated 800 watts. So 400 watts each sub. Too much, yes. So you lower the amplifier's output by adjusting the Gain. You want 300 watts for the combined RMS handling of the subs. The formula for that is Volts = Square Root of Watts x Ohms. Volts = Square Root of 300 x 1 Volts = 17.32 Set your multimeter to Volts AC, connect the leads to the amp's sub output. Turn up the Gain until you hit 17.32. Yes to all this, but the differences are negligible until you get into the high end gear, so don't sweat it. Yes, very important for a long healthy relationship with your gear. The bigger amp hands down. Bass is addictive, so better to have the power for a future upgrade if the bass bug bites. [/QUOTE]
