my rockord's do not work. I connected the power source to the 12 volt battery terminal, ground to batery terminal also and remote to stereo blue wire. I am not getting any power, protection LED lights on top of the amp to light up. I have a an sony amp also and that lights up. So i know i am getting power to the amp. None of the LED's light up on the amp. I have checked the fuse and it is good. I have checked it with an omh meter for continuity and it works. I think i have blown an internal component somehere but do not see any signs of black discoloration any where. Please help me in determining what might have caused the amp to not work. Thanks
