Hi all,

My head unit has only one sub out low level RCA connection and I'm not sure the best way to connect it to the a Gladen RC 600 C1 amplifier. The Gladen instructions don't help much.
Should I:-

1) Connect just one RCA to the head unit and amp. Which side should I use on the amp?

2) Use a Y splitter at the head unit and connect both RCA leads to the amp?
