DMH-130BT

[Bonkersmommi]

Help I'm trying to get my sub hooked up to my pioneer dmh 130bt it but there's only one sub output cable I plugged in the RCA splitter to my sub output and my sub wires but nothing's working

Do you have power to the amp which powers the sub?
A remote turn on lead?
Why do you need a splitter?

If it's only got one (and especially if it's yellow), that is more likely a video input, so you can add a license plate camera. For subs you probably need to find an adapter or a line out converter to use a speaker signal, so you can eventually get to add an amp for your sub. Might be better to just get a new head unit with rca outputs when you figure out the cost, and what you get out of it.
