buying amps need input

I would never use Power Acoustik over RF, and I think Power Acoustik has always been overated (I have one of their more recent amps that claims 170 watts RMS and has a 15 amp fuse....it might put out 100 watts but no where near 170). And they might be stable at 1 ohm for half a second before it exploded. I would also argue that RF's newest line of amps is better then the generation before (like they dont get extremely hot unlike the previous generation of RF). I have never heard or used a Hifonics amp but I have heard that their stable to 1 ohm rating is not very accurate and that their older stuff was definitely better (I think they took the same route that soundstream took). With that said I would go with RF. They make excellent, underated amps and they beat everything else in quality that Best Buy sells. You might try the 8002 if you have 4 ohm DVC subs, if you have 2 ohm DVC subs then your out of look with RF at best buy because they don't make a 800 watt punch mono block amp.
