I'm installing my Sony CDX-GT10W with 2 Pioneer TS -G670M Speakers in the doors. The CD Unit puts out 52 Watts per channel and the speakers will take 220 Watts each. I want to hook up the respective front and rear channels to each speaker because I just need some sound in my 87 Nissan Pickup. Is it alright to use both the front and rear channel for one speaker? Does that push the wattage running through each speaker up to 104 watts? The nominal amount of wattage for the speakers is 50 watts and I want to get enough power to them so they sound decent. Any advice would be appreciated. I'm no expert.
