I am replacing all factory speakers and adding 2 10" MTX subwoofers with Pioneer 300W amp. I am puting 2 4"X6" pioneers in the dash, 2 5"X7" pioneers in rear, and the woofers are going behind the seat. I am looking for the best way to wire my system for the most output I can get. I am not sure where to put the capacitors and I am not sure if I need to bridge my amp or not. Any input would be much appreciated. Thanks, Greg

Use 4 gauge wire straight to the battery and 4 gauge for the ground wire as well. I would bridge the amplifier to 2 ohms and run the subs ( if they are DVC 4 ohms subs ) in series. If the amp can handle the subs to be hooked up in parallel, do so for the most output of the amplifier.
