Sorry, but I could not find an answer to my question. I have an AudioControl D-4.800 amp/DSP that I am going to install in the trunk. Can I use 9 conductor speedwire to grab the signals for my door woofer & tweeter, and then use the remaining wires to power the door woofer and tweeter, in the same bundle of speedwire? Is this the same as running signal wires and power wires together???
