i have a type d alpine mrx-f35 amp installed putting out 75 watts to my front door infinity kappas, i was going to bridge my rear channel and run a sub off of the 170 rms, my question is could i hook up my quantum cozmik 2000 watt a/b monoblock (it won't put out anywhere near 1000 each channel) and run my sub off of one of the channels or would that stress the battery too much?
