    • DONT hesitate JUST CLICK BUY!
Style: Singe 12"
IM SO Happy I purchased this subwoofer and at a great price! The sound quality is great and the subwoofer functions as it should! Definitely recommend buying the Amp that rockville SELLS as well but even with any amp the quality of this is amazing!

    • better than expected.
Style: Singe 12"
OK bought the 4ohm as a test speaker and now love it. I had a kicker 400W amp paired with a 2ohm kicker box. Speaker was very loud on bass type music. Really 2 loud. On non-base music the 2ohm just seem lacking and very punchy. Figured I'd buy this one as the box itself is worth 100$. wow this speaker is nice. after testing was going to replace it with some name-brand 4ohm but now it sounds so good I'm just going to keep it. I'll keep my 2ohm Kicker as a backup. Old: kicker 2ohm @ 300W RMS New Rockville 4ohm @ 150W RMS we will see if she last. I did spend an extra 10$ on Amazon 2yr warranty. ... show more

    • Seller is incredibly helpful
Style: Singe 12"
The product is as described, however, it wasn’t what my husband needed. The seller went above and beyond to make it right and help me with returning it so they are very considerate of their customers.

    • Check your ohm when you get it
Style: Singe 12"
It might have been me but I thought I ordered a different one out of the 3 styles you can order, there was one that didn't show ohm one that said 2 ohm and a 4 ohm, there wasn't much a price difference but I always go for 2ohm and I got the lower one. It's a lot of trouble to return items where I live because you have to go to next county. For the price it does decent but a 2ohm there is a difference. If your looking for loud system with thump this is it. The 2ohm would give you more bass. The three stars is for sending the 0ohm ... show more
