Summary: I have two of these in a sealed box hooked up to a 4x160 watt amp so each one gets 320 watts and they hit hard. Anybody can hear me for atleast 5 minutes away. I want to get 2 more soon and make my system even louder.
Summary: I needed a 2ohm DVC capable of 1000rms. Running 1ohm stable on a Hifonics Brutus amplifier. I bought an Apline Type R figuring its Alpine should be good right? No the sub is over rated. No way it handles 1000 rms. I blew it on day 2.
Summary: An outstanding product needed some something loud and sturdy. It exceeded our expectations.I'm not sure how it compares to others because I have not had to purchase others. This was the best deal.
Summary: Installed 2 in car broke them in properly and 3 weeks later just quit working, checked the amp and signal and there was no problem there replaced the sub and system works good, I wood not recommend at all
Excerpt: running type r 12 with brutus 2000.1 d at 2 ohms so im sending 14oo rms thru these girls once i break them in ill turn the amp up a lil to about 2volts it thumps hard now i notice it gets louder and deeper with the windows down so this summer i should be making some noize yep!
