I have blown one of the factory speakers in the soundbar twice in my 2013 JK, and have decided that I am just going to upgrade the speakers all around. I am going to take out the soundbar and do some sound proofing to reduce vibration. Can anyone tell me what type of speakers are currently in the sound system, meaning are the ones in the soundbar low range/mid range/full range? I want to use Rockford Fosgate Power speakers without going the full component route. I'd like to just pull the old speakers, swap in some new ones, and be done. I just want some speakers powerful enough that when I turn up that head unit I don't have to worry about blowing a speaker, and also having good sound with the top down. Can I just swap out the tweeters, and then put full range speakers in the dash and soundbar and be done? Or should I try to find mid range for the dash and low range for the soundbar?

 

I just bought a 2014 JKU about 2 months ago, first upgrade i did to it was a new sound system.

Headunit was a Alpine CDE-175BT
Amp Focal AP 4340 for speakers mounted under driver seat
Amp Focal Solid 1 for sub mounted under passenger seat
For the front speakers Focal RSE-130 component speaker I was able to use the stock tweeter face plate and just zip tie the focal tweeter to the back of it. For the knee panel the crossover fit inside the speaker box and used some poly fil inside the box.
For the sound bar Focal RCX-130 2 way coaxial speakers. I used sound deadening mat inside the bar on as much as i could touch, then lightly filled with more poly fil. I also added a piece of sound deadening mat to the outside of the sound bar where it mounts to the roll bar.
Sub is a JL Audio CP108LG-W3v3 that i mounted to the rear door.

I haven't had the full top off yet just the freedom panels, but the speakers are nice and clear and the sub while doesnt rattle the rear door you can feel it through the seat and floorboards.

 

Allow me to suggest LOOK at Kicker's.. They make exact replacement speakers that are plug and play for Wrangler and they have a sub too. BTW I have Kickers in the sound bar, OE in the dash and push all of these with a 600w Clarion Marine Amp & a Rockford powered sub under the passenger seat. Have been in use with the factory head unit for a year and have not blown out a speaker yet. Food for Thought
