    Running a Plat 2 12 with high performance and tall surround on an American Bass PH4000md powered by a Singer 250a and im in love. tight bass and deep lows. cant tell me theres a better sub for the price.

  2. Mitch Mulcahy (verified owner)

    Running 2 platform 2 12s with high performance on 2 psi 2500s strapped. And damn they get down! Have givin them everything they got and still want more! Couldn’t recommend this sub enough! Wont be disappointed!

  3. Nathan Streich

    Had two platform 2 12s in my old impala ran them at 3600rms at 0.5omhs and it slammed by far my favorite system I ever had since then I only run psi subs
    Always quality builds and equipment and would recommend them to everyone!

  4. Aramy (verified owner)

    Good beefy sub good sound quality and gets loud also nice looking to boot

  5. Anthony Petree (verified owner)

    This subwoofer started my PSI addiction. I had it hooked up to a star power 1500 wired to 1 ohm and as long as you feed it clean power it will perform. Of course the boxes you place them in have an effect I had mine in a 2.5^3 ported box tuned to 34. Great excursion to hit the lows and stiff spider to hit the punchy rock music. Great daily driver subwoofer

  6. Ruben (verified owner)

    Awesome sub
    . Have one 12 installed in my mustang. Saving up for a matching amp and soon a platform 5

  7. Mike Leach

    My Platform 2 12″ is amazing in my Drew Jones 4th on a Orion XTR2500

  8. Al

    I bought two of the high performance version, on 2500 watts they are hardly moving at all, yet the whole car is trembling. They play with authority, I can’t wait to double the power going to them. You would not think they’re just two 12s

  9. Ed

    Top quality. I have a platform 2 with the hp upgrade with a skar rp2000.1 in my hatchback and it pounds!

  10. Daddy buddy

    Best thing I could have Asked for I mean the sub it’s just amazing and I could ask for something so loud and clean.
