    • Easy to Install, Vast Upgrade from 27 year old OE Jeep Sound Bar Speakers Easy to Install, Vast Upgrade from 27 year old OE Jeep Sound Bar Speakers
Review Image by S. Wheeler
Review Image by S. Wheeler
These replaced the crummy old paper speakers in the sound bar of my 1993 Jeep Wrangler YJ. Those had completely deteriorated, with warped paper cones, and foam rubber surrounds that had almost totally disintegrated. So compared to those, these Kickers are fantastic! But what I really like are the fact these are low RMS (15-75 watts), meaning the original Jeep AM/FM tape deck I have has no problem powering it since it produces 20W/channel. I could install an amp, but why bother when these sound so good? No, they don't come with grilles, despite what the product description says. That was no problem for me, since I wanted to reuse the original grilles in the sound bar to keep it looking stock. These Kicker speakers fit perfectly, their low profile size had no problem clearing the factory grilles and the hole spacing lined up perfectly. I didn't have to drill anything! I attached photos to show how discreet they look behind the factory grilles. They do come with speaker wires that has spade terminals already attached, as well as butted crimp connectors for hooking it into your existing wiring. These were a little expensive, but I didn't buy a 27 year old jeep because I thought restoring it was gonna be a cheap hobby. I'm very happy with these speakers overall and am excited to replace the dash speakers with some Kickers this weekend! ... show more

    • Where Price meets Quality - Buy them
I wanted to upgrade the dash speakers on my Tesla RWD Model Y which comes with a standard amp and no sub woofer. Even the headliner tweeters dont work, So picked these speakers. Installed them and they dint ring much on day one. Once they breaked in, the clarity was mind blowing. The vocals, guitars and cymbals came out so distinct and crisp. Buying coaxial due to lack of tweeters really served my purpose. If you are not keen on buying top shelf speakers like Alpine etc, go ahead and get this guys. you wont regret. ... show more

    • Does not fit FJ Cruiser
sure its a solid speaker, but it does not fit an FJ Cruiser D pillar for anyone looking for rear speakers.

    • Great stock speaker replacement.
Used to replace stock speakers in 2018 Jeep Wrangler. Sound is so much clearer.

    • Great sound
Easy to install. For such a tiny speaker very surprised on the quality of sound. Even has good bass tone. Would recommend for the small spaces. Good quality speakers feeling them.

    • Not as good as expected
I bought these to replace sound bar speakers for the rear of my JLU. I had previously purchased a set for the front (kickers but Mopar for Dodge Dart) and they were awesome. These are OK - more high sounds (and maybe volume?)but less bass than the cheap paper cone stock speakers. For the price I'm disappointed. ... show more

    • Sound Great / Flush Face
I was replacing speakers in a arcade unit and I wanted a two-way, flush face speakers and these fit perfect! The tweeter is flush to the frame but it also includes a 1/8 inch spacer to be sure the speaker surround does not make contact with the surface I mounted them to. They sound great & meet what I would expect from a 4 inch speaker- Clear highs down to mids, some bass but a speaker that small is not going to produce much bass. ... show more
