Hi ! Welcome to IRV2! We're sure glad you joined us!
Congrats on the new rig! Hopefully someone familiar with your rig will be along to help. Those speaker wires must be in that cabinet somewhere. Have fun and keep her between the ditches!
It will make it easier for folks to help if you create a signature showing the make and model of your RV. Look at post #30 in the link below that tells you how to do that.
Good luck, happy trails, and God bless!
