Do I need to upgrade my speaker wire?

04 TJ. Upgrading my stereo system. I bought polk 5 1/4 components for the front and and polk 5 1/4 for the sound pods. I will be running 75 watts rms to each speaker. Will the OEM speaker wire be large enough or should I run larger speaker wire?
Thanks in advance.

Are you adding an amplifier? If not then the stock wiring is plenty enough for those speakers. Even adding an amplifier that wiring would be sufficient, it's just that you would need to add wire anyways if going with an amp, so why not upgrade.

Yea I am adding an amp under my steering column. So I was going to splice from the amp to the speaker wires behind the head unit, which would only be about 2' from the amp. From the research I have done several people go up to 16 gauge, but some stay with the stock wiring. I was hoping someone who may have done the same upgrade to their system would chime in.

i used the passenger side to run the wires because i have my amp power cable down the driver side and didnt want to risk having any static interference

Thanks in advance.
The standard Polk 5.25 speaker will not handle 75 watts RMS. The speakers might say 135 max power, but this is not RMS. Those Polk db521 speakers are only rated at 45watts RMS. 75watts RMS will clearly blow them.

I overlooked this point when I amplified my Infinity Kappa speakers and blew them out. I had 100watts RMS going to them, and they are only rated at 60RMS. The speaker had totally ripped away from the housing. I even doubt the total accuracy of the RMS rating on my front Infinity Kappas. My front speakers blew out with an allegedly 60Watt RMS rating, but my back speakers(5.25), with a 55RMS rating, were fine. It doesn't make since. More likely, my smaller 4x6 speakers were only 45RMS.

Luckily, the place where I brought my Infinity speakers and my amp, accepted the blame for selling me inferior speakers for my system. They took back the blown speakers, upgraded all my speakers properly, only charged me for one set, and Warrantied them for three years. I made the bad assumption that since they were reputable speakers with a great name, that they could handle anything. I was wrong, and although I knew about RMS, I overlooked it. Don't make my mistake, by accepting max power, and assuming RMS. I knew, and I could slap myself for overlooking it.

So far so good. I don't plan on cranking it up to where people in the next county can hear it.

Just so you are aware to be careful. Sorry to be so "long winded".
