Being a RF employee, I get a chance to beta test some of the units that we have created this year. Right now, I am currently testing the Power T15004: 125 W X 4 @ 4 Ohms RMS 250 W X 4 @ 2 Ohms RMS 375 W X 4 @ 1 Ohms RMS 500 W X 2 @ 4 Ohms Bridged RMS 750 W X 2 @ 2 Ohms Bridged RMS It is 1ohm stable! It is pushing out a lot more than the rated power though...for example: 125W x 4 @ 4 ohms RMS...it is doing 300W x 4 @ 4 ohms RMS!!!!!) The current draw isn't too bad either...(I only have the amp running on 1 channel though.) From what the engineers are telling me though, it is drawing about 200-300 amps at MAX POWER. Here's the kicker: The total RMS (all channels combined) is over 2600 watts!!!!!!! I have 2 RF Punch HX2 2ohm DVC subs in the back of my explorer, wired to ONE channel of the T15004 at 2ohms. I can tell you that they BUMP. I haven't had any problems with distortion, engine noise, or anything else...I have practically no complaints!
