Hi, ive just finished spending 4 hours installing my fli active sub and fli 800 amp and speakers. I have a small problem with the power cap. It seems that it remains on even though i have everything switched off? It doesnt come with a remote connection and im sure that i have connected it correctly. I have it in parrallel with the amps power supply. Is it supposed to be in series because this would explain how the capacitor would switch off automatically? Thanks
