I have space behind the fireplace where the pantry is so I hope this can be done.
Sorry, didn't realized it was standard in RVs. It sounds like you have a car unit so you will need a car amp, and a car sub woofer. If it was a home unit I was going to suggest a soundbar with a wireless sub. However, you'll need to pick a sub that will fit where you want to install it...an amp to match your sub and the wiring in between. If you can DIY it shouldn't be too hard. If not, take it to a shop to get it done. Good luck and Cheers, AL
