Hey guys i was just wondering if i wanted to power 2 subs off this amp http://www.ryda.com.au/Kenwood-KAC-9103D-Car-Amplifier-p/kac9103d.htm
is it possible? do i have to find particular subs cause i have no idea what this ohm stuff means etc.. could i run these two subs from it? or would some more powerful subs be better? http://www.ryda.com.au/Clarion-DP12XB-2-x-12-Subwoofers-in-Box-p/dp12xb.htm

thanks

These guy's recommend single voice coil 4 ohm sub's for a single mono amp.

the pic explains it all, that's how you would run 2 single voice coil subs to a monoblock.

base on RYDA website picture, you dont need to worry if you only running 2 subs with SVC 4ohms or 2 ohms but not 1ohm, just hook up both subs into the Amp since they are 4 speaker terminal already on the Amp and the Amp will bridge it internally, you dont need to follow the previous diagram

unless if your subs is DVC then is gonna be more complicated
