Holy nuts. This one is TOO easy... the kicker! Volfenhag, especially their amps, is complete flea market junk! Trust me, I have seen countless volfenjunk amps that were blown in less than a year.
Look how cheap and cheesy the volf looks.. fake "2400 watt" power rating nice and big on the front, cheap chrome tacky looks, its half the cost of the kicker for a reason.
These are 2 different amps though, one is a mono, one is a 2 channel.
The 2 channel wouldnt even work ideally for a pair of single 4 ohms subs like your kenwoods.
The kicker wins, hands down.
