Is it better to run the speaker wires directly to each speaker or just run the 4 wires behind the radio and connect them their? Since I will have to run rca's it would probably be easier to just splice them in behind the radio.

It's up to you, but generally it's much easier going behind the deck. I like to make one taped loom that consists of my RCA's, remote trun on lead, and speaker wire. I start form the amp and go up to the deck. I also run power wire from the amp forward, usually on the opposite side of the car from the RCA's.

It all depends how much work you want to do and if you think the stock wiring is sufficient. I ran new wire because i am running more powerful speakers and I just wanted to upgrade the wiring. It was hard to feed those wires through the molex's though. That is a hard task if you have never done it before.....

we are discussing coaxials not subwoofers... there is absolutely no sound difference you could ever notice from using the factory wiring to running your own.  There just isn't a strong enough demand for current to affect your amp's performance.

If you were running a powerful amp for subs, then you want thick wire...

He was not specific enough on his equipment to make the conclusion that the current demand would or would not affect anything. We dont know what amp he has or what speakers he has. He asked a general question. I gave a general answer.

i disagree with you on the sound difference. You say there would be no difference?? But then you say if you we were talking about subs then we would need a thicker wire because of the demand of the amp. What if he has some high powered mid-bass in the doors? I think in that type of situation it would be best to upgrade the wiring.  But once again, we dont know what he is working with.

Oops sorry. No I don't need to upgrade the speaker wire. I just have 4 kicker coaxial 6x8's and a 85wattx4ch@4ohms stereo Amp. For my Subwoofer amp I usually use a larger gauge wire to the speakers. I'm not sure exactly its gauge but its bigger than 16 gauge.

i read his question.. he mentioned the option of connecting to the back of the radio.. that can only imply he is connecting to the factory locations,, even with a midbase driver.. how much could he possibly push? 150 watts?

my answer still stands.. and he only confirmed it...

and i didnt say there would be no sound difference, i said there would be no noticeable sound difference.. please read entire comment before responding.. its in the details..

by the way, factory wiring will not be larger than 16 gauge.. and it doesnt matter..

the sub response... well.. generally subs, since they drive low frequencies, require lots of power, and in DC.. thicker wire provides less resistance.. in this application thicker would be better. 

If he was running higher frequencies.. he would want smaller wire, and a fast switching amplifier (high end for best results)to reproduce the high frequencies more accurately.

anything else?
