I have a pdxf4 and now that my rear deck alpine spr 60's don't work, (long story) I am just running the alpine R components on channel 1 and 2. Now that I have the weekend to work on my system, I'm wondering what I should even do. The components are 110rms so bridging would be 200watts to each side. Should I do that and turn the gain way down, would it be worth saving for good midrange speakers for the rear? Or maybe some bomb tweeters I can run to their own channels? What is my best move? Screw my ruined speakers, I don't like knowing half my amp is being wasted!! Advice please!!!
