Review: You only need one 12” - This thing RIPS!! I only have an 800watt RMS skar amp on it and everything is wired to 1OHM but I replaced the SLS 750watt rms with this one and the punch is harder, the lows are lower, and there is soo much room for growth in this setup buts it’s just a jeep wrangler daily driver so we will see. Best speaker I have ever owned hands down. Pricy yes but they shipped it fast and packaged it well.
Review: Great subwoofer , small footprint with big sound - Exceeded my expectations, great subwoofer. Ordering another one. Was running 2 8 inch CT SOUNDS subwoofers and one of the solo x 8 inch sounds as loud as the 2 8's i previously had , i want more so going to install dual 8 inch kicker solo x 8 inch subwoofers

### ⭐⭐⭐⭐⭐ BEST SUBWOOFERS ON THE MARKET!!!
*by G***R on June 27, 2025*

Wow! These bad boys are amazing! I burned out my L7s and was determined to replace them only with Solo X. These hit incredibly low, and there’s no comparison between them and any other kickers out there. The price is high, but trust me, it’s worth it. Make sure you have enough power to push them for the best experience. The cones are extremely stiff and flex significantly, showing very high excursion. They weigh about 70 lbs each. THEY DO NOT FIT THE SAME SIZE AS THE L7s. While they can sit in the box, they will leave holes around some edges, so I am working on getting a custom box built. Otherwise, I am really enjoying my new SOLO Xs.
