I am going to be installing a new subwoofer, amps,and speakers into my 2000 Acura TL. I am also going to be keeping the factory head unit. My question is should I just use the speaker wires already in place or should I buy new speaker wires and replace the factory wires?

 

Personally, I always prefer to use new wire. But since you're keeping the HU, it may not be necessary.
