  • These subs my best friend has owned for six months now and have hooked up to a Phoenix Gold Titanium 600.2 amp. When turned up about 3/4 of volume can quite literally take your breath away. Not Bad for being 16 uh?

  • Can't say anything other than this sub rocks! Using a single 12" wired for 2 ohm off a Phoenix Gold Octane-R 9.0:5 amp at roughly 300 watts in a sealed enclosure under the rear seat of a 2000 GMC Sierra. After buying the new Westside Connection CD and plopping it in the Alpine HU I thought I was in a lowrider in L.A. (being in a 4x4 in Texas). I'm scared to hear what two of these would do. The salesman at the local shop couldn't get me to replace this with a JL sub if he paid me! Magazine reviews constantly hold Diamond at or above JL subs every time and Diamond is cheaper. Great product.

  • These subs BANG!!!! For the money they are completely worth it! I compared these subs to some JL w6's and w3's and they out compete both of them!

  • This must be one of my best buy i've ever comited. I'm running 2 12 at 1500 watts with a 4 guage wire and let me tell you that there is no real way of explaning the real deal. Most of of one of mu buddies got 4 12 impp he also ran 1500 watts and it wasnt as half as decent as mine... if your looking for something that will wang this is it...

  • economic for those who want to rattle the windows out of their ride... im running 2 in a large ported box in my trunk of my neon.... and it rattles my teeth... and i still have the stock head unit... plus only running 1000 watts to subs

  • I'm running two of these with two 1200W MA Mono amps at about 800 RMS apiece in a 2002 Jetta. Jettas are notorious for not being able to bump because of the thick backseat. No problem with these. These are OBSCENE. They handle everything that the amps throw at them. No distortion, no cracking, no nothing. If anything, I should have gotten 10's cause I underestimated what these speakers can do. I've tried alot of subs in the past including Kicker and Punch. These more than hold their own. And they cost less too.

  • The 10's sound great in a box as small as .6 cubes and the 12's sound great in .7 cubes. These subs are amazing... I swear by them. I gladly replaced JL subs with these and will never go back. People are still paying way too much for used JL subs on ebay, and could be getting a new Diamond CM3 sub for less. Sorry for all you less fortunate out there who have not discovered Diamond yet!!!
