    These subs bump hard

    Posted by Jerry on Mar 30, 2025

    I replace the Skar EVL 12's with these subs. I'm running 2 of these subs paired with a Sundown SFB 5000 and they can take all the power the amp puts out. These subs sound clean and hits the low notes with authority. I like the carbon fiber cap and it matches the carbon fiber I have in my Jeep. For the price this a budget banger for sure. Thank you JP for offering this subwoofer for us budget bangers.
