Adding Polyfill to the stock Subwoofer enclosure to make it sound better.

Has anyone tried this on the OEM subwoofer that comes with the Overland?

I know from the F150 forums, I learned about this for the stock Sony subwoofer box under the rear passenger seat. The mod worked great on my F150 for the cheap cost of some polyfill.

I'm not sure whether this is doable with the Grand Cherokee since the sub is mounted in the side wall. Has anyone had a look behind the sub to see if there is room to put in the polyfill?

Re: Adding Polyfill to the stock Subwoofer enclosure to make it sound better.

If I were to tear it all apart, I'd do a whole lot more than that. I'd add more mass to the enclosure (bedliner, sound deadening, fiberflass, etc.), seal it, add polyfill, replace the driver with a real subwoofer, add an inexpensive mono amp, and button it back up. You have to nearly rip the whole rear interior apart to get at it. Adding polyfill is not going to make a difference worth that task.

I haven't heard the Ford Sony systems, but this worhtless OE Alpine sub isn't worth messing with. Most leave it, or replace it.

Ahh OK.....that's too much work to just polyfill it. With the F150, it was easy, just unbolt the sub box & fill it.

Re: Adding Polyfill to the stock Subwoofer enclosure to make it sound better.

Greetings,

The wiser choice is to replace it. But, do take notice, once you have replaced it their is a very good chance you a going to start replacing other speakers and adding additional aftermarket equipment.

Search this forum and will find some good ideas here.

Best for now.
