quick question.. if i was to replace my stock front speakers or my stock rear speakers would i also have to replace the existing speaker wire or could i just use the factory wire?


thanks

 

only replace the speaker wire if your running the speakers off of a amp, not the head unit

 

Like Wiltshire559 said if they are powered by the H/U the OEM wiring is more then sufficent. But if you are amping them it may or may not be necessary to change the wire, it depends on the vehicle make and model and how much power you have.

I didn't run new wire in my Maxima and I have 80 wrms per door, but the OEM wire is like 14 awg. But if it was a Honda or GM product I would suggest it.

 

depends on the stock speaker wire size, how much power you're running, and the length from the power source. check the awg rating, if it's 18 awg or lower(thicker), then it's fine for up to 125 watts @ 20 feet and 4ohms( you'll lose about 15 watts at the speaker, which is only .5 dB's in output...not detectable to most people). To give you another example; if you have 16 awg wire that is 60 feet long, you can run up to 370 watts through it at 4ohms before it drops below 300 circular mils/amp, and you will only lose 1.0 dB's in output( I would not do that, as it's ideal conditions etc...). I've been running my 470 watts(mids/tweets) through my factory wires for a long time with no issues. Basically, most factory wiring should be at least good enough for up to 100 watts with no issues.
There is a calculator at:

go to the site, go to #16 on right side, and scroll down to speaker wire calculator. You can put in all your values and it will let you know if it's o.k.

 

kick ***.. thanks guys
