4 gauge (or so) amp wire, rca cables

I want to put my stereo back in my car once I get my alarm installed. I need cable for power and ground. The battery is already in the trunk so I don’t need a ton of it. 4 gauge sound about right? also need rca’s, and remote wire.

thanks

ive got 8 gauge. power wire, ground, rcas with remote wire built in, inline fuse with holder.

15$

I might have a 4 or 2 gauge lying around for $20. I will check tomorrow.
