Ok guys. i have the msr3007 jensen marine head. i have an alpine pdx 4.100 amp. i have 3 thin wires coming down from the head. ground, remote and power.. the ground is grounded to a metal switch. the remote is wired to the remote insert in the amp, and the power leads to a fuse and then to a little box where the battery wires go. I turn the system on but the head doesn't,turn on, the amp just flashes blue. this was in my boat when i bought it and was working fine. i added additional speakers, they worked but now i worked on it today and this has happened. i attached the left and right amp outputs to the amp, just like it was originally. any ideas?? Thanks for your time
