Questions

Can this amplifier accept high level input wires from my speaker line out on the head unit? Simply cut the rca ends off of the wires or how are the connected? And what is max input voltage please. Thank you.

Asked by: centralcoaster
Hello, the amplifier cannot accept a High-Level input connection without the addition of a hi-to-low converter. Hi-To-Low converters are available third party.
