The average length to go from my headunit to the very rear of the car.
High quality shielded cable only! I’m getting alternator whine and my RCA’s are opposite power/romote wires… 
i have monster rca cables.
interested?
Please let me know the length and a model number or link to a site of the product.
I really need some quality wire, the rest of my setup its A+ except for using 2 crappy rca’s and one quality one. All grounds/power go strait to the battery via 0/1 or 4 gauge, all power and signal wires are run opposite of eachother :S and the amp i mounted as far away as possible from disturbances…
