  • Quality speaker
Style: Singe 12"
Great sound and enough bass for price.

  • Excellent box and woofer!
Style: Singe 12"
Very impressive bass for a 12" woofer. Comparable to the old punch 15's from the 90's. I basically stole it on sale for $99 bucks. Worth every penny and more. perfect size for my little truck too.

  • Not bad not great
Style: Singe 12"
Decent build and sound. Found out later i want more rms and volume. If you're looking for average sound like a factor installed system you'd be ok with it. I wanted deeper lows so returned.

  • 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
