I just purchased a replacement stereo/CD player and speakers for my aging Nissan P/U. I only have room for door speakers (maybe subwoofer in the future). The stereo has outputs for front and rear speakers at 50W each for a total of 200W output. Since I have no rear speakers...can I run the rear speaker's output (in addition to the front outputs) to my front speakers for more power (you know, say 100W)? Crutchfield's online FAQs kinda answered my question but not exactly in black and white. I could call them but I'd thought I'd toss it out here instead. I'm putting this in myself as I'm an ultra cheapskate.
