Using rear channels to power subwoofer

So, I would like to power a subwoofer (either 1 or 2 subs) with the rear channels of my f700bt. I have a single cab tacoma so i don't think i need a dedicated sub amp, but i would like to squeeze as much power out of the f700bt as i can without hurting it. (looking at 1 or 2 JL Audio 8 inches) In the installation manual it states that i could power 2 subs (left and right) or use just the right rear connection to push 2 ohms into 1 or 2 subs (manual says this would be 70 watts instead of 50). but wouldn't that only be one push of 70 watts at 2 ohms instead of 2 of 50 watts at 4 ohms? which one would be more powerful? Thanks in advance!

Don't even bother. 2 jl's powered by an f700 would barely move. Just get an amp and use the rca's.it will be much more worth it and you won't kill your radio

yea i wouldn't even think about trying to drive any sub solutions off of the internal amp, just not enough power to push anything
