Polaris Slingshot Fiberglass Under Dash Subwoofer Enclosure (Fits two 6.5" Subwoofers)
If you're looking to maximize sound in your Polaris Slingshot, you may consider adding one of these Fiberglass Passenger Side Under Dash 6.5" Subwoofer Enclosures by Underground Auto. Up until now, the only way to add sub woofers to your Slingshot was by utilizing your rear storage compartments. This hand laid fiberglass sub enclosure allows you to mount two 6.5" subwoofers underneath your dash to give you the bass your stereo system deserves without compromising your storage compartments. These UnderGround speaker pods come standard with a black textured finish. These pods bolt directly into place and do not interfere with your factory glove box.

This is off the hook AWESOME! Does reduce the drop of the glovebox some but who cares!

Pain in the neck Install
If you have a 2017 SL with the STANDARD Rockford Fosgate side panel speakers, this system will work but only with modifications and is a real pain to install. After calling manufacturer direct they stated it will fit but it'll be tight (that's an understatement). Side panel has to be installed but loosened and rotated so enclosure can be slid up behind it (their video shows install without the side speakers installed). Even then, cant fully tighten sub enclosure since both systems want the same space. Poor design, great sound.

Great enclosure!
If you have the DEI heat shield kit installed, the bolts that attached the heat shielding behind the factory muffler location uses the exact same holes as the bracket for the enclosure does. Those bolts hang down maybe a 1/2 in or so behind the glove box preventing the sub enclosure from fitting properly. My solution to this was to remove the bolts and reinstall then from underneath the glove box area sticking upwards into the engine bay and then applying the washers and nut on top to secure the enclosure bracket and the heat shielding on top of the bracket. I then used my Dremel to cut the heat shield back slightly to expose the two center holes on the sub enclosure bracket. Once I made these slight mods, the enclosure went it with a little muscling just fine. I added two JL Audio 6.5 subs and a 300W JL Audio amp and now I have very tight musical bass without sacrificing any of my behind the seat storage.

Great addition, one minor mod to note
Paired with the JL subs and a corresponding mono amp, this really made a huge impact on the sound without compromising storage space.

I did run into an issue where I had to take them out but then the screw kept spinning as I removed the nut from the engine compartment. I ended up having to cut off the bolt and put a new one in. There is a second nut that holds the bolt in place and if it gets loose, you have a problem. Unscrew those nuts and add loctite to keep it secure. It should come from the supplier this way.

JL Audio complete sound system !
Ok so I have the JL Audio Stealthbox Front Pods with 7.7" Marine Speaker set that wouldn't fit with this Sub enclosure but that didn't deter me from performing some work to make it fit and believe me it was well worth it......The JL Audio subs that I have in there with the front pods and my rear JL Audio pods is unbelievable........Also with the added bass switch coming from my JL Audio amp , giving me control over my bass on every single song.....Didn't want to give up my trunk space and thought of the underseat woofer but I'm more than glad I went with this one instead !
