I'm planning to change my spearkers tomorrow, I've got 2 set of component speaker and 2 amps that I want to intstall. One 250/2 amp going to the speakers, and the other one 600/2 going to the sub-woofer. I don't have my sub or my headunit yet, those will be arrive sometime next week, but I just to get a head start on my project. I'm planning to just use the stock wire, since this is only for daily driving. I'm thinking of using the stock rear speakers wire to connect to my amp for the input, and from the amp goes back to the rear speakers. Then I'll use a new wire from the amp to the front spearks. So I'll be runing 2 spearkers in each channel. Do you guys think this is going to work?? Or is there any better way.

 

You could do that but I think you would be better off just running another speaker wire back to the amp. It might be a pain to get to the rear speaker wires. If you are running RCA's or a remote turn on from the amp then running speaker wire won't be any extra trouble.
