[QUOTE="DARKHART, post: 8354672, member: 544747"] This is a huge fallacy that stock factory wiring is crap. I would say that for 85-90% of most installs using aftermarket amps, the factory speaker wiring is just fine, especially in newer or European vehicles. Hell in my 16yr old BMW all the factory wiring are twisted pair and we're seeing this more and more on newer vehicles. As far as the 9wire is concerned, it's simply a 9 conductor cable with the industry standard color coded pairs that make for an easier and neater installation. When using amps you can run a single length of 9wire to the location where all the factory speaker wiring converges (ie factory amp) and tie in there which saves time for the installer and cost to the customer. It's very easy to say "hey they should have asked me if I wanted to run new wiring to each speaker because I'm a purest" but all to often customers limit themselves with price. Just as easy as it would have been for the salesperson offer that as an option, you could have said "hey I'm picky about my sound and I want new wiring run throughout the vehicle." So there is no reason to be pissed and the statements made earlier about the noise being picked up by the speaker wire, well Trumpet gave the best response to that. Truthfully if you weren't building a major sq style of install most wouldn't even offer or suggest running new wiring to the speakers because it's not really needed unless you are using a majorly powerful amp which in turn would require speakers designed to handle the power.
