According to Chris @ db-r, it is a solid 2kw+ amp @ 1 ohm, and I have found it to do rated or very close to rated @ 2ohms (1700w) and @ 4 ohms (850w). In this respect it sounds like in terms of output we could compare it to a beefed up kicker zx1500.1 or something? One that is also perfectly 1 ohm stable? for what like 350 shipped brand new with warranty? Sounds like a **** good deal to me
Some people have also claimed to have found that they have gotten full rated power @ 1 ohm or close to rated, as I believe OP did, so who knows...with good voltage and enough battery power behind it, it may be possible to get a solid 2.5kw out of it
Some people have complained in terms of reliability, but that is debateable...I've run mine on a single batt and weak alt for months and I beat the hell out of it, dropping to 11's in voltage sometimes, and it usually doesn't even get hot...I have absolutely no complaints about mine, in fact, I bought a second one //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
