Recommendation for a dedicated line wire

Looking to wire my room with 2 dedicated lines - one for the amps and one for the sources. I will appreciate your recs for an in wall wire. I need about 60' for both lines and I'm trying not to spend more than $20 a foot.
Thanks in advance.

I used 12awg Romex with very good results.
Can pick it up at most hardware stores.
