I searched the forum and I found a lot about running RCAs next to the power wire (which i'm not doing because I have cheap ones ($8 for 17ft haha)). Anyways, can I run my RCAs right next to speaker wire?

No.The rule of thumb is to always run speaker wire down one side of the car and signal/power wire down the other side. If you run speaker wire beside RCAs they will interfear with eachother and you will get noises through your speakers. If, during the install you Must cross them, do so at a 90 degree angle

So running the rca's and power wire wont cause any problems? It is only an 8g power wire since my amp is only 200w rms

No problem...reguardless of the guage of the wire

How about current draw amount?

And amplified signal will not pick up induced EMI. Low level signal wires (rca's) will pick up EMI from power wires, not speaker wires.

My mistake. The rule is *power wire down one side and signal wire (which includes speaker wire) down the other side of the car. Sorry for the confusion

Yeah, you can run speaker wires and RCA's together.
