Good reviews.
Rodney A on Jun 23, 2016
is 8 gauge pwr sufficient for this amp?
A shopper on Jun 19, 2016
Best Answer: It is probably okay, but I used 4 gauge. 8 gauge is normally rated for up to 125 amps at a maximum length of 7 feet, so it depends on your wire length and intended volume levels.

the rms rating is 210x4, so does that mean 210 per speaker in a 4 speaker set up?
Kerron J on Feb 1, 2015
Best Answer: According to the user manual for the 5-channel MOSFET amplifier:
MAX POWER (2 Ohms) 300W x 4 + 600 W x 1.
RMS POWER (2 Ohms) 210W x 4 + 420 W x 1
RMS BRIDGED (4 Ohms) 420W x 2

Speaker Impedance is: 2-8 Ohms.
I can't post link to user manual, but U can find it in planetusa(dot)com
