Ive seen the Front Door Connectors you got to drill out and such to run new speaker wire but is it easier for the rears. I'm gonna run JL AUDIO 6 1/2 Mid-Subs in Rear doors and it would pay in power for me to bridge the rear channel of my amp to get down to 2 ohms(Yes its a 2 ohm stable Punch AMP) and double up the power to them, but now that I think about it couldn't I do it from under the front seat with whats there, I'm old been awhile forget all the parallel and series stuff...lol Now I got to go look it up, may have answered my own question.
