2001 300m wiring help

[rctecinc 10+ year member]

I need help wiring a 300m. I really dont want to remove anything form the interior. I have recently installed infiniti kappas in the front doors location. But I didnt install the x-overs. I have 3 amp to use and a set of 12 inch mb quarts subs.

The stock amp is in the trunk of the vehicle and i was hoping i can wire stuff from there.

If anyone knows which rout I can take please let me know.

you're still gonna have to run new power wires... you can bypass the amp at the amp... that's what i would do... match the wires coming out of the headunit... with the wires at each speaker you wanna use for positive and negative... sorry if i'm not clear on this as i just woke up... if you can... mount your crossovers in the doors so you can just run the speaker wire to input and run your speaker wire to your speakers instead of running new wire throughout the car

Still going to need at least 4gauge and set or 2 of rcas running back there. What might be a decent idea for RCAs is to run them right down to the center console under the console then into the carpet as opposed to tryin to run them across the dash and along the sills.

I was hoping I didn't have to run new wires. How about just changing out all the factory speakers? And the factory amp, whats the output in rms?

The thing is that factory amp is fairly low wattage and the wiring to it is not designed for an aftermark amp. Your preety much limited to replacing factorys and then running a new amp. According to your sig you already have a sub amp back there? What kind of wire size you have running to it? If its like 1/0 just get a distro block and then u just have to worry about another set of rcas from the HU
