Hi guys! Really need some help on this one! I installed a FLI active enclosure in to the clio over the last few days and can't get it to work properly:-/. RCAs are running down a separate side of the car to power and remote, it is grounded to where the rear lights ground on the right, when I turn the gain up even past a quarter all I get is very loud pulsing like a heartbeat, my interior lights also pulse with this and my rear wiper goes off? Wtf right? Can anyone help with this?? Also I am using a kenwood kdc-bt41u if that helps. Thanks in advance. Also no power errors on the unit.
