I know that it is 120W "RMS" (which I've been told that is an erroneous term) but there is another kind of watt. I don't know how it is called. The kind that stereos use in stores.
2x20 Watts
how many watts does he amp have in a 2005 chevy impala
100 watts is great, 150 watts may be too loud for some, and there is higher watt amplifiers made.
It mainly has 10W,20W,30W,50W,60W,80W,100W,120W,150W,180W,210W,240W,300W,360W.
The Alpine v12 MRV-F505 amplifier puts out up to 200 watts of RMS power at 4 Ohms and using 12 volts. At 14 volts, it puts out up to 400 watts of RMS power with a bridged 4 Ohms ratio.
50 watts is a good amplifier size for use in the house. For other applications speakers usually have a power rating.
90 watts X 4 channel output
Xenyx 802 is not a powered mixer, you need a separate amplifier with it to drive the speakers
volts x amps = watts so 1500watts/12.8volts=117amps
The Rockford Fosgate R150-2 2-channel amp puts out 50 watts RMS per channel to your speaker system, or you can bridge it to supply 150 watts RMS to a subwoofer.
What's a subs? If you are consuming 3200 watts your amps at 120 volts will be 26.6, at 240 volts it will be 13.3. However I suspect I am missing some information.
As many as the watts or current the dimmer specs say it will control - less 10 percent
