FLI Underground Performance
Getting the most bang for your buck has never been easier. The new FLI Underground line of speakers offers great full range sound for an affordable price. These entry level speakers are a excellent choice for factory replacement speakers, as well as speakers that are powered directly off an aftermarket audio receiver. They feature a electroplated injection molded polypropylene (IMPP) cone that delivers fast and articulate bass. The PEI tweeter and midrange combine to produce outstanding high frequency response. The butyl rubber surround delivers an improved lower frequency. All of these things join together to create a full range sound that is comparable to speakers two to three times the price. For those looking to a cost effective way to get some higher end audio, the FLI Underground speakers are the ideal solution.

  • Power Handling:
    • Peak: 240 watts per pair / 120 watts each
    • RMS: 80 watts per pair / 40 watts each
    • Minimum Input: 20 RMS per speaker
  • Electroplated injection molded polypropylene (IMPP) cone

'99 TJ; Rep from Jeep Beach

I replaced my sound bar and to front speaker with these speaker. I have an after market 4x45W stereo. The a 100 times better than the stock speaker I had I my TJ. I also had to buy the adapter for my front speakers which was well worth the money, even though you can make them yourself with spec from jeep forum online.

CONs: I will say that the speaker covers that came with the speaker are trash because they vibrated which was bothersome. I just use my stock speaker covers.
