Multi use sub-woofer question

I know there is a lot of RV expertise in this forum but I'm also hoping there a few audiophiles posting here as well. I am looking to replace the large heavy sub presently installed under my dining room seat with something more compact, accessible, and easily removable. The idea being that during driving I would have the sub connected to the dash radio and finally be able to hear some low ends frequencies outside of the rumble of the RV itself. Of course while camping it would be connected to the house radio for some full range music and then on outdoor movie night or campground picnics I'd move it outside the rig.

Now this might be asking a lot for what seems like a simple thing, but so far I have failed to find the right solution. Is there anyone out there that has done something similar or have idea's that might help?

PS. I have a 2016 3011

Not sure what you mean by "more compact, accessible, and easily removable". I put a 10 inch Bazooka tube with the built in amplifier under the side facing couch. It fits just fine and is very accessible, although I've not found a need to access it. Even though the amp is only 100 watts it will chase you out of this small space (3051S) if I crank up the volume.

At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.

I was thinking about getting the six inch bazooka and mounting on the floor between the driver seat and the side couch where the slide ends when retracted. These are secured with velcro or straps correct? They may even have modular plugs for wire connections. In that case I could wire both sources to the sub and change the connector depending on which source I was listening too. Also, if i wanted to use the sub outside, I could just unstrap/unplug it and move it.

OK. So after considering multiple options and configurations I settled on a compromise solution that would enable a new sub woofer to be shared between the house and dash radio and on those few occasions where we are at a tailgate or some other outdoor event, I'll bring the old Jensen sub woofer with me and hook it up for outside use.

Phase #1 - The new sub woofer is a Rockville RW8CA ($100) which is an under seat model that use's very little space. This model is 150W (600W max) and is about 1/3 the size and 50% lighter than the Jensen sub. I mounted it on the inside house wall that connects to the cab behind the driver seat. This location is not on a slide and is fixed (Sub1). In this location the sub can be easily heard when driving and when the slide is out (Sub2) it gives the house radio a much tighter and less boomy bass than the Jensen sub did mounted under the U-Dinette.

Phase #2 will be wiring the house and outside radio's to one one of the lower compartments where I will install and use the Jensen sub as needed for outdoor events. This is officially on the todo list now.

After our 600 mile trip last week, I was quite pleased with the results. I can actually hear the bass from the radio now while driving without having to worry about blowing out the door speakers.

Note - I previously installed a pair of Infinity Reference REF-8632CFX speakers in the doors. While this did improve the sound tremendously, they still did not provide the low end response at a sound level I was looking for. Adding the sub behind the driver seat really filled in this gap.

Quick Update - The final part of this project was to install the old sub in the lower compartment below the TV. I installed it so that is was removable using a quick connect 6 terminal connector and also switchable between the inside house radio (using 6" outside main speakers) and the TV/Radio and smaller 4" speakers. After recently coming back from a 2 week trip where we spent a lot of time outside the RV the results were really good. The sound watching movies, TV and listening to the radio was much improved and even my kids questioned why it sounded so much better now.

We keep it low and at our age now we are ready for bed at 9pm so bothering the neighbors is never an issue.

The 4" speakers outside just don't cut it especially when we are are in a noisy environment such as a tailgate which we do several a year.
