Good morning! As the title states I have a couple questions about my sound bar that I'm hoping someone can help me out with? I have a 2015 JK Wrangler Sport I bought it used and had a sound bar already inside and seems stock/have been told is stock. I would like to upgrade my speakers/ add a couple more speakers if possible. I can post pictures to help show/explain it better but there are a couple empty spaces it looks like adding speakers is possible. Do they sell direct replacement speakers for sound bars or just use similar size universal speaker? Any recommendations on speakers? How many speakers are normally in a JK sound bar? I don't want a crazy stereo just something sounds good and loud enough to hear over my roof top tent/awning when installed. Thanks for your time!

 

Those holes are for the freedom panel screws. Can't say I've seen anyone try to put speakers there.

 

I just upgraded my soundbar over my 2 week COVID break. I used replacement speakers JBL from Crutchfield. On YouTube are many clips where you can dampen vibration of the plastic soundbar with an inexpensive ~$17, 1/16" thick foil/adhesive from Home Depot. I rolled it, pressed it with a spoon etc. The other tip is to fill the soundbar with polyfil like that used in pillows $5 at Walmart. All of that did help the bass response some and eliminate some vibration .

"Repair tape" used inside and some outside of front speaker pods for vibration dampening.

 

As to speaker upgrades, MOPAR KICKER speakers are the easiest upgrade - Plug & Play . buy on line multiple sellers &/or local dealer can order. Great sound, have in my 2016 with a 600w amp.. 100 w per channel or 50w RMS per channel.. I did stuff it with Polyfill.
