[QUOTE="pro-rabbit, post: 619879, member: 551878"] In reality this amp will not do 4k @ 2 ohm with 14 volts. It will do more like 3k max. I own a few of these and do testing all the time. Mine are modded and run them on 16V batteries(charged to 18V). I burp at .3 ohms. I have tested these amps against many other amps to see how this amp really stacks up. Amazingly with a 16V+ system this is one of the most powerfull amps you will buy. However, with a 12V setup unless you have a few yellow tops you will not like it. The amp will work at 2 ohm ONLY! with 12V if you drop any lower on 12V(unless burps) the amp will fail. Just for reference the Clif Design CDX-20A(which I owned), Visonik VX4000D(which I owned), and MA Audio HK4000D(wich I now own) are all the same amp. The differnces are minor now with new construction and design. The CDX-20A was geared more towards better sound, but all in all they are the same. I run the MA Audio HK4000D because of the casing it uses. They will never get hot and they use a digital voltage meter which is nice if you need that. The CDX-20A and VX4000D both have solid cases and use 2 fans. One fan blows in and one fan blows out. This is a nice setup, but they do tend to get hot with long term use.
