I recently purchaced a refurbished planet audio p850d amp off of ebay........I bought it to be able to upgrade my subs to some of better quality....i have an audiobahn abp10 dual 10" bandpass box now.....

......well the p850d has to be cranked way up almost all the way in order to get decent power to my subs at 2 ohms.......I hooked a friends 10" dvc sub up to it wired at 4 ohms and it barley did anything and what sound it did make was a farting sound....>I was not impressed!!! His sub rocks his car with only 150 rms from his mtx and at 4ohms my p850d should be pumping 350rms..............WHAT GIVES??????? DID I get a dud? I tested the amps ohm load with my subs and it reads 2ohms and the amp seems to function completly but it just doesn't put out the power it says it should!!! I am not sure if I should send it back to get it fixed or if some amps just don't push some subs well for some reason...............Has anyone gotten any of these planet audio refurbished amps off of Ebay??? Anyone have the same experience........Im sort of a newb so Im not sure maybe Im expecting too much from this amp....AM I????

Any feedback from anyone who knows more than me would be appreciated.............................PEACE

Are your tweeters amplified or powered by the radio or maybe factory amp? I'd check your wiring for sure, make sure 12v power and ground are both connected properly, and fuses, to be safe...
